How long does conception last after the act. When does conception occur? Characteristics of male reproductive ability

The birth of a new life is something special. On the one hand, we all learned at school how conception occurs. On the other hand, even scientists have not yet fully explored all the subtleties of this amazing process. For a woman who is preparing to become a mother, it may not matter at all how the fertilization of the egg occurred, the main thing is that the baby is healthy. But for many couples who want to become parents and are unable to conceive or experience repeated miscarriages in early pregnancy, issues of ovulation, conception and fetal development become especially important.

How does ovulation and conception occur?

A woman can give birth to children during the fertile period, which lasts from the onset of the first menstruation at 11-16 years of age until the onset of menopause at the age of 48-55 years. Every month, under the influence of hormones in the female body, one, and sometimes several, eggs mature. The release of a mature egg from the follicle for fertilization is called ovulation. A healthy woman often does not even feel when she has. She may feel a slight tingling in the lower abdomen and a slight rise in temperature. But going about her business, a woman most likely will not even feel that something has changed in her body. But those women who cannot conceive for a long time, specifically try with or.

After ovulation, the released egg waits for fertilization in the fallopian tube for 24-48 hours. And if sexual intercourse occurs, several dozen spermatozoa approach its walls. One of them penetrates her shell. At this point, the chromosomes of the egg and sperm fuse, forming a set of 46 chromosomes, necessary for the conception of a new life. And the formed zygote moves along the fallopian tube into the uterine cavity in order to gain a foothold on its wall.

What happens after conception? When the embryo is attached to the uterine cavity, the formation of fetal membranes begins. One of them, which is called the chorion, forms the placenta at 7-14 weeks of gestation. From the placenta to the fetus there are vessels that form the umbilical cord. Fetal cells are constantly dividing, forming new tissues and organs. And each of them carries information from the mother and father of the child.

What day is conception

This question interests most parents, since many of them want to determine the exact day when their baby was conceived. But if the couple is sexually active, it is difficult to establish the moment of conception. Gynecologists consider the beginning of pregnancy the first day on which she came. But in fact, you can conceive a child only during ovulation. Therefore, you need to look for the day of conception somewhere in the middle of the menstrual cycle. It is important to remember that a mature egg can live for 1-2 days, and sometimes even 5. In addition, it is necessary to take into account the fact that spermatozoa that have entered the woman's genitals live there for up to 5-7 days. And this means that you can already forget that you had sex a week ago, and ovulation and conception will occur in your body at the moment when you go shopping, sit at work or chat with a girlfriend. And it is very difficult to calculate exactly when a new life was born in you.

Many women are also concerned about the question of how to find out if conception has occurred. In the first days after successful fertilization, only the expectant mother herself can feel the pregnancy. Some call it intuition, and some attribute it to tangible changes in a woman's body that begin to occur immediately after conception. After a few weeks, pregnancy can be detected through a baby test, which will show the presence of a special hormone in the woman's urine. And only for periods of more than 2 months, the doctor can feel a characteristic increase in the uterus during.

Why doesn't conception occur?

We have repeatedly discussed this important issue on our website under the topic. If a couple fails to conceive a child for a long time, both partners are offered to undergo a full examination. A woman is checked for hormonal levels, looking for possible problems in the reproductive system (through ultrasound and others), a series of tests are taken to exclude possible infectious and inflammatory processes in her body. A man is done to check for the presence of viable spermatozoa, and they also conduct a study on infections and.

There can be many reasons for women. But often conception is prevented:

• Inflammatory processes in the female genital organs, leading to. If tubal patency cannot be restored, apply the procedure. It is very effective in this case.
• Changes in the structure of the female genital organs, not allowing to endure pregnancy. Then the only way out for the couple is surrogate motherhood.
• Violations in the menstrual cycle, when the egg does not mature, and ovulation does not occur. In this case, hormonal therapy helps.
• The low fertilizing properties of the sperm of a man do not allow to conceive a child.

At the moment, there are many that allow couples to conceive, bear and give birth to healthy children. Therefore, you should never despair. Be sure to contact the experts and make every effort to make your dream come true. But, despite the fact that we are always trying to completely control our body, doing complex tests, drinking hormonal drugs, calculating the moment of ovulation, monitoring the maturation of follicles, the conception of a child is still the greatest mystery that happens in our life. Therefore, it is pointless to study it, you just need to hope.

On what day after conception do the first signs of pregnancy appear? This issue is of great concern to women, especially young people. Behind an outwardly solid and correct question lies the desire to calm oneself down and get an answer to the question - on what day after sex can signs of pregnancy appear?

The first difficulty lies in the fact that conception does not occur at the time of sex, but over 5 to 14 days. It is also worth noting that the hormonal background of the body changes for another 10-12 days. This means that the first tests can show pregnancy no earlier than 15-20 days from the moment of sexual intercourse.

However, the female body can give its own signals about whether the fertilization process is completed or not. We will talk about this and other issues related to manifestations in the first days after conception.

It is also worth mentioning here that the process of conception means the completion of sexual intercourse. Do not forget that the period of conception can reach several days. Expect the most accurate result no earlier than 4-5 weeks from the moment of intercourse. Earlier attempts to test can lead to the so-called "false negative" result, when the test shows that there is no fact of pregnancy, but in fact it already exists or will occur in the near future.

How long does it take to get tested for HCG?

HCG or pregnancy hormone provides fairly reliable information about the fact of pregnancy in the first days after conception. In the body of a non-pregnant woman, such a hormone is not produced. According to the developed program for determining pregnancy using the hCG hormone, an analysis for its presence / absence is given 15 to 20 days after sexual intercourse, which is considered conception.

Does basal body temperature change after conception?

The change in basal temperature in the first days after conception is that it remains elevated. However, there is a “window” in such a change, when the basal temperature decreases for the period when the embryo is implanted in the uterus. Such a phenomenon has received the definition of "impantational retraction."

Is it possible to conceive immediately after menstruation?

Yes, in the first days after the end of menstruation, conception is not only possible, but these days are considered favorable for it.

For information - the possibility of conception always exists, that is, on any day, even when menstruation is coming. It was written above that the process is not instantaneous and its effectiveness and duration depend on many factors.

Is it possible to conceive after ovulation?

Ovulation itself (the fact that a mature cell leaves the ovary) is necessary for conception. Moreover, without ovulation, conception is impossible.

However, the very first stage - fertilization occurs only on the first day after ovulation. If it does not happen, the egg dies. This fact helps to determine that the highest probability of conception is 1 to 3 days before ovulation, as well as directly on the day of ovulation.

If sexual intercourse occurs after 12 - 20 hours after ovulation or later, conception will be unlikely.

Calculation of favorable days for conceiving a child

The main criteria for the calculation should be the regularity and duration of the menstrual cycle. The most favorable is the day of ovulation and 1-3 days before it. Having calculated on which days of the cycle this period falls, plan conception.

Determination of the date of birth by the date of conception?

It is worth noting that childbirth can occur earlier or later, even by 2-3 weeks, since the body of every woman has soy features. This is not a pathology, only a feature. Many women instinctively feel the first signs of conception and can more accurately determine the date of birth.

Does the date of conception affect the gender of the unborn child?

Every family really wants to give birth to a child of a particular gender, and sometimes two at once. Unfortunately, no modern methods of family planning or calculators for calculating the sex of the unborn child work. The female egg carries only YY chromosomes, that is, only female. The spermatozoon carries the XY chromosomes, both male and female. The gender of the unborn child depends on which pair of chromosomes will merge in unity in the first days immediately after conception. Man has not yet learned to influence this process.

A huge amount of information presented on the Internet that there are methods to increase the likelihood of having a child of the right gender is not true. 50/50 chance.

The only way to predict the sex of a child is to conceive him in the laboratory in the process of artificial insemination.

What processes occur in the female body in the first days after conception?

The body is actively rebuilding and preparing for pregnancy. The hormonal background changes, the uterus increases in size, its walls become thinner, the cervix closes. One of the ovaries turns into a hormonal generator, a corpus luteum is formed in it, which produces hormones to maintain pregnancy.

What are the feelings in the first days after conception?

A large number of processes simultaneously occur in the body, which directly or indirectly affect our physical and emotional state. The fact of conception is not felt by a woman, although many do not think so.

Most of the symptoms presented as symptoms of conception (not to be confused with pregnancy), such as nausea, drowsiness, abdominal pain, mood swings, loss or increase in appetite, and so on, have nothing to do with conception. These manifestations would have appeared anyway, and the woman subconsciously or consciously attributes them to conception. Having studied in detail the process of conception and the first days of embryo development, you will understand that there can be no changes that could affect the state of the body and manifest itself externally or internally.

It is also worth noting that women often try to find signs of conception in themselves immediately after intercourse or in the first hours after it. It was written above that the period of conception from the moment the sperm enters the vagina to the fact of fertilization and the movement of the egg can be several days. Therefore, any sensations associated with the signs of conception are far-fetched or imposed from the outside.

The first signs of pregnancy (precisely pregnancy, when the hormonal background has already been rebuilt) appear in the majority at 2-3 months, and many feel like future mothers when others notice a rounded tummy.

Can abdominal pain be the first signs of conception?

Pain in the abdomen within one to two weeks from the moment of sexual intercourse has nothing to do with the possible conception and, especially, pregnancy.

Two weeks later, in the case of conception, when the embryo is in the process of implantation in the uterus, that is, it is looking for a comfortable place for itself, some (not even most) women may experience mild, pulling pains in the lower abdomen, reminiscent of pain during menstruation.

Similar pains, in a more pronounced manifestation, appearing on the one hand in the ovarian region in the period of 2-3 months after conception, may be evidence of an ectopic pregnancy, when the embryo develops in the fallopian tube or miscarriage.

What does discharge after conception mean?

Discharges of a bloody nature, brown or pinkish, observed immediately or up to 4 days after intercourse, have nothing in common with conception. In this case, they are harbingers of early menstruation or signs of various gynecological diseases.

If such discharge appears after 1 - 2 weeks, when the process of implantation of the embryo occurs, this is a consequence of this process itself. Such discharge does not last long, 1 - 4 hours.

Brown or bloody discharge observed between 3 and 12 weeks after conception is most often a sign of a miscarriage. Most women do not pay attention to them, taking them for menstruation, because they have no idea about pregnancy.

Bloody or brown discharge that began after 8 to 12 weeks is most likely a sign of an ectopic pregnancy or miscarriage. Such discharge may be accompanied by pain in the ovarian region on one side and pulling pains in the lower abdomen.

What does nausea and vomiting mean in the first days after conception?

A fairly large number of women, especially those who do not want pregnancy within 1-8 days after sex, feel nausea, and sometimes vomiting. They consider these manifestations the result of pregnancy, or rather the toxicosis associated with it.

These manifestations have nothing to do with pregnancy or conception in the period from 10 to 40 days from the moment of sex. Most often these are far-fetched symptoms, sometimes food poisoning. It was described above why the manifestations of pregnancy cannot occur in the first weeks after sex.

For reference. Toxicosis of pregnant women manifests itself at least from the 8th week of pregnancy. Many women may not experience it at all during the entire period, many feel it as a reaction to new foods that are eaten.

How to behave after conception?

There are some rules that should be observed after conception:

After 14 days from the moment of sexual intercourse, consult a doctor to examine and determine whether the embryo has attached to the uterus correctly, whether there is an ectopic pregnancy or other pathologies;

Do not take any medications that have not been discussed with the doctor in advance when planning or confirming pregnancy;

If before conception you were undergoing treatment or taking drugs for chronic diseases (epilepsy, asthma, arrhythmia), do not stop taking them, but notify the doctor about the pregnancy as soon as possible, and the obstetrician who is seeing you about how long, what specific and in what doses of medication you are taking;

Continue to eat everything you ate before, the main thing is not to be zealous with seasonings and spices;

Leave the daily routine and sports activities unchanged, the main thing is to exclude overwork.

Should you continue having sex after conception?

Yes. Continue sexual activity without restrictions, however, if there have been problems with pregnancy or bearing in the past, consult an obstetrician.

Is alcohol harmful after conception?

Definitely alcohol is bad. And in ordinary life, it is harmful to the body, and in the process of conception and pregnancy, when there is a restructuring and hormonal changes, it is doubly harmful. Limit all alcohol consumption throughout pregnancy and breastfeeding to zero.

Against this background, many expectant mothers are very worried that they drank at a party or event the day before or on the evening of conception. Such experiences are absolutely in vain, because while the process of fertilization and conception is going on, any alcohol will already be removed from the body.

What should smokers do when they conceive?

A lot has been said and written about the dangers of smoking in general, and especially during pregnancy. Nicotine is produced by the body and is used to break down certain amino acids. Smoking releases nicotine from the outside and the body stops producing it. Therefore, after giving up cigarettes, discomfort is felt for some time - this is the body restarting the process of producing nicotine.

Pregnant women should definitely stop smoking. If you cannot do this on your own, any smoking pills and patches should be discussed with the obstetrician and therapist before use so as not to harm the child.

In the first days after conception, smoking will be harmless to the fetus, but you still need to limit the number of cigarettes you smoke. Weakness now can come back to haunt a child after many years.

How do birth control pills affect conception?

All contraceptives approved for sale, including pills (oral contraceptives), create a fairly reliable protection against unwanted conception. Such drugs do not have any effect on the body, they bind the hormones involved in the process of conception. At the same time, in the future, when the family decides to conceive a child, the rejection of contraceptives will lead to a complete restoration of hormonal balance, which will in no way affect the woman’s reproductive ability.

Each contraceptive drug has its own recovery time. Most often it is about a few weeks, less often a few months.

Outcome

Early conception does not in any way affect a woman's physical or emotional health. Almost all "symptoms" and "manifestations" are far-fetched or imposed. Soberly assess the situation and determine for yourself the options for its development. Do not pay attention to the advice of friends and acquaintances, especially those who have not given birth.
If conception has occurred, do not rush to have an abortion or be upset. Discuss this with your family, the birth of a child is a gift and happiness for a woman.

How many days after the act does conception occur? We will try to understand this issue further. We will also learn the basics of pregnancy planning. What do you need to know about this woman? And when can you have unprotected sex without the risk of soon becoming a mother? Answers to these questions and more will be offered below. In fact, everything is not as simple as it seems. And even giving birth girls will not always be able to quickly understand the area under study.

About the menstrual cycle

On what day after the act does conception occur? Unfortunately, there is no way to quickly understand this area. It all depends on the specific situation. Therefore, we will further consider theoretical data and real facts. They will help you understand when you can have sex without protection and the risk of becoming parents.

The female body after puberty is faced with hormonal processes. For example, with menstruation. The period between critical days is called the menstrual cycle.

Depending on this indicator, the time of conception and the periods when a woman is more likely to become a mother will change.

The menstrual cycle is:

• normal - 28-30 days;
• short - 15-25 days;
• long - 32 days or more.

In addition, sometimes there are women whose critical days come in different ways. It is more difficult for them than others to plan children. After all, it is extremely difficult to predict the next menstruation.

How long after the act does conception occur? And when are the chances of success highest? In addition to the length of the cycle, it is necessary to understand into which phases the time is divided between critical days. A lot depends on this.

Phases of menstruation

The thing is that the risk of pregnancy in a woman with unprotected sex is always there. But on certain days of the cycle, it is higher. And this is normal.

There are such stages of the monthly cycle:

• follicular;
• ovulatory;
• luteal.

The chances of getting pregnant increase during ovulation. Within a couple of days, the success of conception will be minimized.

During the follicular phase of the critical cycle, it is almost impossible for a woman to become pregnant. After all, the egg is not yet mature. So, you can not worry about an unwanted pregnancy.

About the process of conception

How many days after the act does conception occur? First, let's talk about this process in general terms.

With the beginning of a new menstruation (or at the very beginning of one or another "critical cycle") in the female body, the egg begins to slowly mature and develop. After monthly bleeding, the follicular phase of the cycle begins. It is characterized by the active growth of the female cell.

During ovulation, the egg is released from the follicle. At this point, she is ready for fertilization. Next, the egg moves to the uterus through the fallopian tubes. This process takes about 48 hours. And it is at this time that a successful conception of a baby can occur.

Having reached the uterus, the unfertilized egg will live for about 2 more days. After that, she dies. The luteal phase begins - the period of preparation of the body for the next critical days.

Fertilization by spermatozoa

When does conception occur? It can take a long time after intercourse. Not every modern girl is aware of the details of the process being studied. This is why sometimes unwanted pregnancies happen. You can try to avoid them.

Consider the general case - when a couple intentionally plans a pregnancy. So it will be much easier to understand the topic under study.

Suppose unprotected sex fell on the period of ovulation. Spermatozoa enter the female body and begin to quickly move towards the egg. She is now ready for fertilization.

Only the fastest and most active sperm can enter the egg cavity. This moment can be considered a successful conception. It takes from 2 to 6-7 hours. So, after ¼ of the day you can talk about the onset of pregnancy.

However, everything is not so simple. You won't be able to recognize it right away. This happens much later.

After fertilization

What changes and processes occur in the female body after a successful conception? What happens to the egg? She begins to divide and move through the tubes to the uterus for attachment and further development. This "journey" lasts up to 7 days.

After implantation of the female cell in the uterine cavity, active growth and development of the fetal egg will begin. And after 14-15 days, a pregnancy test should show two strips.

How long after the act does conception occur? The egg can be fertilized in six to seven hours. After unprotected sex, it attaches to the uterus on about 20-24 days of the menstrual cycle. But the girl should not have problems with ovulation.

Sex before ovulation

How quickly does conception occur after intercourse? This process can take from two to seven hours. That is why, in case of emergency protection with oral contraceptives, it is recommended not to delay taking the appropriate pills.

Some wonder if sex before ovulation can lead to pregnancy. Yes, if he was unprotected.

The point is that:

• ovulation may not come on time;
• spermatozoa live in a woman's body for some time.

So, it is impossible to say with certainty that planning a child is possible only with ovulation. It's just that with sex before "X-day" conception will occur a little later.

About the life of spermatozoa

On what day after the act does conception occur? There are a lot of options for the development of events. But they all depend on ovulation and on the viability of spermatozoa.

Ideally, male cells ready for fertilization can live in the female body for about a week. This means that pregnancy during ovulation can occur even when unprotected sex has been a long time. Such situations are not so rare.

Sometimes sperm live in a woman's body for only 1-2 days. Fortunately, this is an extremely rare occurrence.

Success symptoms

We found out when conception occurs after the act. The symptoms of this event are almost impossible to feel. At least until the egg reaches the uterus. There, as we have already said, there will be attachment to the wall of the uterus for further development. This process is called implantation.

That is what women can feel. During implantation, there is a slight pain of a pulling nature. It is felt in the lower abdomen. Sometimes there is implantation bleeding - a few drops of blood or spotting from the vagina. Bleeding lasts from a couple of minutes to 3-4 hours.

body temperature and conception

How long after the act does conception occur? We have already dealt with this issue. There is no way to answer it unambiguously.

Let's talk a little about ways to determine an interesting position at first. This can be done without much difficulty only for certain categories of girls. For those who keep a chart of basal temperature.

If BBT stays at around 37.5 degrees Celsius for 3-4 days longer than usual, one can judge a successful conception. But this option for determining an interesting position is not suitable for everyone. You will have to wait about 2 weeks before the manifestation of pregnancy in full swing.

The first signs of pregnancy

The process of conception can be carried out both a few hours and a week after unprotected sex. Both situations are quite normal. After all, sperm live in the body of a woman for some time after ejaculation. And they can wait until ovulation with an egg ready for fertilization.

Now consider the first real signs of an interesting situation. We are talking about a situation in which more than 10 days have passed since fertilization. That is, the time of the next critical days is approaching.

At this point, it is customary to single out the following phenomena:

• an increase in the abdomen;
• swelling;
• toxicosis;
• pain in the abdomen;
• intolerance to certain odors;
• mood swings;
• fast fatiguability;
• drowsiness.

In addition, a clear sign of pregnancy is a delay in menstruation. If the bleeding does not start on time, it is recommended to wait a couple more days and take a pregnancy test. By this time, 2 stripes or "ghosts" should appear on it.

Important: you can take a blood test for hCG. An increase in this hormone in the body most often indicates a successful conception. But the process is best done on the day of the delay in menstruation or after this incident.

What affects ovulation

How long does conception take after intercourse? This process takes no more than a few hours. But sometimes it takes a very long time to wait for "X-day". Especially if a woman has problems with ovulation.

It is important to remember that the rate of egg maturation is influenced by various factors. And so conception can happen unexpectedly. All days of the cycle are conditionally considered "dangerous" in the absence of planning an interesting situation.

Doctors most often identify the following factors influencing ovulation:

• bad habits;
• stress;
• fatigue (emotional and physical);
• change of weather conditions;
• chronic diseases;
• taking oral contraceptives;
• STDs;
• the size of the menstrual cycle.

This is not a complete list of circumstances that can speed up or slow down ovulation. But it is these factors that occur most often in real life.

Anovulation and conception

Sometimes, even with unprotected intercourse, a woman does not become pregnant during the expected ovulation. Why is this happening?

If a man is healthy and has motile sperm, it should be assumed that in one or another menstrual cycle the woman had anovulation. This is a process in which there is no ovulation. With him, critical days can come after 2 complete cycles.

Important: normally, anovulation can occur in a girl no more than 2 times a year. Otherwise, it is recommended to consult a doctor.

Anovulation is not possible under any circumstances. After all, in fact, in the body of a woman, the egg for the studied process will not mature. This means that there will be no pregnancy.

When does ovulation occur

We have studied everything. How many days after the act does fertilization occur? This question won't be a problem anymore. And as you can already see, successful fertilization occurs only during ovulation. This period may start earlier or later than the scheduled time. But when to expect ovulation?

With a normal cycle "day x" you can wait for 12-16 days from the start of the last critical days. Ovulation usually occurs on the 14th day. This is normal.

With a long cycle, the favorable time for conception is 20-25 days of the cycle. If the difference between the critical days is small, you can wait for "day X" for 7-10 days.

Important: There are different methods for determining ovulation. And the principle proposed above is called calendar.

How to determine ovulation

When conception occurs after intercourse, we answered. And we also got acquainted with some features of this event. A few words about how to determine the favorable time for conception.

At the moment, there are such methods for determining the "X day":

• calendar;
• test;
• medical;
• physiological;
• according to the BT schedule.

We have already dealt with the calendar reception. Now let's explore other scenarios.

If you determine ovulation according to the basal temperature chart, then it is worth keeping records of several menstrual cycles. BBT is measured daily. The indicators are plotted on a graph. During ovulation, body temperature reaches 37-37.5 degrees Celsius.

The physiological method of determining the favorable time for conception does not differ in its effectiveness. But women often observe in themselves during ovulation:

• increased sexual desire;
• increase in vaginal discharge;
• pain in the ovaries and in the abdomen.

This method, as already mentioned, should not be relied upon. It is better to give preference to other methods of determining a favorable day for conception.

For example, test. It involves conducting a rapid test at home. The measuring device resembles a pregnancy test. The woman should urinate on the test strip and wait for the result. One line - ovulation will not come soon, two - it is a favorable time for conception. It is recommended to do the test in the middle of the menstrual cycle.

The most reliable method for determining ovulation (including pregnancy) is a medical way to translate ideas into reality. It is based on an ultrasound examination. The operation is performed approximately in the middle of the menstrual cycle.

On ultrasound, the specialist will see not only the position of the egg, but will also be able to report the onset of pregnancy. To accurately "catch" ovulation, it is recommended to carry out the procedure every 3-4 days from the middle of the monthly cycle.

Results

How long after intercourse does conception occur? Ideally, this process takes several hours. But in exceptional cases, sperm in the female body can wait up to 7 days for the right moment.

We have studied all the features of planning pregnancy and determining ovulation. Now there shouldn't be any problems with it.

It doesn't show up right away. And even doctors will not be able to say for sure whether a girl will be able to become a mother at one time or another. You'll have to be patient and wait a bit. For example, before the delay of menstruation.

How many days after the act does conception occur? It only takes a few hours! If a woman does not want to become a mother, she will have to carefully choose contraceptives.

Collapse

Healthy women ovulate regularly. How to find out if conception occurred after ovulation? Neither a pregnancy test nor an ultrasound will give any result immediately after ovulation, because hCG is not produced in the pre-implantation period. After the fertilized egg attaches to the uterine wall, and hormone secretion begins, a test can be done. Up to this point, a woman can record the initial signs of pregnancy, which are far from always objective.

Favorable period for conception

Is it possible to get pregnant before ovulation or after it? The maximum chance of conception exists on the day of ovulation. Favorable time after it is calculated in hours and averages less than a day. This is due to the fact that the oocyte lives only 12-24 hours. The potentially dangerous period is about 8 days (7 days before the release of the oocyte and 1 day after it), since the spermatozoa live from 2 to 7 days. That is, they can penetrate the tubes even before ovulation occurs, and wait for the egg there. In this case, conception occurs on the day the oocyte is released.

Ovulation

To calculate ovulation, you need to divide the average cycle time by two, the error is three days in both directions. This method is not very accurate because ovulation may occur earlier or later than the middle of the cycle. The test for LH (luteinizing hormone) in the urine can accurately determine the output of the oocyte. An increase in the content of LH indicates the approaching ovulation. The test allows you to find out about ovulation a day before its onset with an accuracy of 99%.

Signs of pregnancy

To understand that conception has occurred, specific signs will help, signaling a change in hormonal levels. Pre-implantation symptoms of conception and fertilization are not reliable, but sometimes they accurately indicate the presence of pregnancy.

Bloody issues

Minor spotting that appeared after ovulation may indicate conception, this is implantation bleeding that accompanies the introduction of the embryo into the uterine wall. These discharges are often mistaken for menstruation. But you can not ignore the spotting, which repeatedly appear during the day or more. This could mean a threatened miscarriage, a condition that requires medical attention.

Bloating

Long before the onset of toxicosis, a woman may complain of increased gas formation and bloating. These symptoms can be considered a sign of pregnancy if they occur towards the end of the cycle.

Some note intolerance to certain foods and smells, unusual food addictions. These phenomena disappear with time, but having become pregnant again, the woman already clearly knows what the occurrence of these symptoms indicates.

Cramps in the abdomen

Also, many women indicate such signs of pregnancy as heaviness in the lower abdomen and cramps, sometimes tingling and pulling pains. These symptoms may also indicate an increased tone of the uterus, so if they last a week, then you should consult a specialist.

Changes in the mammary glands

Soreness, enlargement and engorgement of the breast, enlargement and darkening of the areola are the main signs that conception has occurred. These phenomena occur before menstruation, but at the beginning of pregnancy they are more pronounced and can last longer. Also, a woman may notice a light discharge from the nipples, this is the mammary glands begin to produce colostrum.

High basal body temperature

If fertilization has occurred, then the entire second half of the cycle should remain elevated basal temperature. Sometimes the sensations when the egg is released are mistaken for the onset of fertilization, since the symptoms that occur during ovulation are similar to the signs of conception. It is more reliable not to rely on subjective feelings, but to wait for the 10th day of the alleged pregnancy and take a test.

After fertilization, the basal temperature rises. If the thermometer is 37 degrees, this allows us to conclude that pregnancy is possible even before the delay. After ovulation and fertilization occurs, increased production of progesterone begins. It is he who gives an increase to 37 degrees.

Normal temperature after fertilization is an unfavorable prognostic sign and indicates a lack of progesterone. This condition poses a threat of miscarriage and needs treatment.

Fatigue

The initial signs of pregnancy include increased fatigue, sleepiness and a constant feeling of malaise, which is caused by hormonal changes. The body after ovulation and conception adapts to a new state for it and provides protection to the embryo. If pregnancy occurs after ovulation, immunity automatically decreases so that the mother's body does not reject the embryo, which it perceives as a foreign body.

Irritability
An informative sign of pregnancy is severe irritability and emotional lability, which is also a reaction to hormonal changes taking place in the body. If a woman is nervous and annoyed for any reason, then this may indicate a conception has occurred.

Increased PMS symptoms

Unpleasant sensations after ovulation and conception may resemble discomfort before the onset of menstruation. They are evidence of the onset of pregnancy. Severe and prolonged pain may indicate abnormal attachment of the egg, so if they continue for more than 14 days, then it is worth visiting a doctor.

Stomach ache

In the first days after conception, sometimes there are mild pains in the sacrum and discomfort in the lower abdomen. More pronounced pain appears with a threatened miscarriage or ectopic implantation, in addition to it, blood discharge occurs.

Gastrointestinal dysfunction

Sometimes the first signs of conception after ovulation are associated with dysfunction of the gastrointestinal tract. If more than a week has passed since the expected moment of conception, then a woman may experience the following symptoms:

• nausea, urge to vomit;
• heartburn;
• increased gas formation;
• heaviness in the stomach;
• taste perversion.

These symptoms occur when conception occurs after ovulation and the egg is implanted in the thickness of the uterus. Before this happens, the hormonal background remains at the same level and any changes in the functions of the gastrointestinal tract are not informative.

Cystitis

The early stages of fetal development in many women are accompanied by inflammation of the bladder. The reason for this phenomenon is not so much that the growing uterus presses on the bladder (it still has a size no larger than a chicken egg), but rather in the hormonal changes in the body. Immune defense is weakened, as a result, the infection penetrates into the organs of urination and cystitis develops. Problems of this nature can haunt a woman all the time of pregnancy. Treatment is carried out with antibacterial drugs that do not have a negative effect on the fetus.

Signs of conception by day

For the fusion of gametes, it is necessary that a full-fledged egg comes out of the follicle. The mature cell is capable of fertilization and subsequent division. On what day after ovulation does conception and fertilization occur? Most often on the same day, the life of the egg is short - about 12-24 hours.

First day

Spermatozoa must travel a certain distance to enter the fallopian tube, where the egg is waiting for them. This process takes about 2-6 hours. After the struggle, the sperm penetrates inside and fertilization occurs. Signs of conception after ovulation before implantation in most cases are absent. A woman does not feel anything on the 1st day of pregnancy.
Second day
The immune system perceives the fertilized egg as a foreign body, therefore, on the 2nd day of pregnancy, the production of antibodies begins, the so-called immune attack. From this, the expectant mother feels tired and weak. In addition, on the second day, there may be a change in taste preferences, bloating and nausea, as well as signs of fertilization of the egg, such as engorgement and soreness of the mammary glands.

Third day

The first few days, including day 3 of embryo development, take place in the fallopian tube. A woman may lose her appetite, experience nausea and dizziness. Starting from the third day, the woman's body begins to rebuild and prepare for implantation.

Fourth day

On the 4th day after the fusion of gametes, thanks to the peristalsis of the tubes, the embryo enters the uterus. Signs of pregnancy on this day: increased gas formation, bloating. Sensation of a foreign body in the abdomen.

Fifth day

Implantation means the process of attaching the embryo to the uterine lining, which occurs between the 5th and 9th day from the moment of fertilization and lasts about 40 hours. If the embryo does not move into the uterine cavity, but continues to develop in the tube, then an ectopic pregnancy is formed. On the 5th day after the fusion of gametes, the temperature may rise, dizziness and chills may occur. The woman feels like she has a cold.

Sixth day

On day 6, there is an increase in basal temperature, which must be measured without getting out of bed in the morning. Drawing pains are felt in the lower part of the abdomen, as before the onset of menstruation.

Seventh day

A sign of pregnancy on the 7th day is: slight light brown or pink discharge. They may occur between the fifth and seventh day after gamete fusion, corresponding to the implantation of the embryo.

eighth day

The beginning of the second week of embryonic development corresponds to the first critical period of formation. During this period of time, teratogenic factors lead to the death of the embryo. But if he survives, then he does not have any malformations. On the 8th day there is a feeling of constant fatigue, headaches and dizziness. The expectant mother looks pale.

Ninth day

The embryo, which is at the stage of crushing, reaches the uterus and begins to sink into the mucous membrane. This sometimes causes minor implantation bleeding. Until the 9th day, the signs of pregnancy are very scarce and similar. Due to the fact that the hormonal background begins to change, the expectant mother feels very tired, therefore, on the 9th day after the fusion of gametes, the woman feels drowsy.

tenth day

On the 10th day, the embryo is finally implanted in the uterine mucosa. Now you can determine the presence of gonadotropic hormone in the blood. A biochemical blood test, which can be done from this day, objectively confirms the onset of pregnancy. After 10 days, you can use a highly sensitive test.

Eleventh day

In most women, the approach of menstruation is accompanied by some characteristic sensations: mood lability, pulling pain in the back or lower back, migraine, engorgement and breast enlargement. And if on the 11th day these signs are absent, then it is possible that it is no longer worth waiting for menstruation.

Twelfth day

On the 12th day of embryonic development, dyspeptic phenomena may appear: changes in taste, nausea, vomiting, rejection of certain odors. These symptoms of fertilization occur in the vast majority of expectant mothers. At this time, the body itself can suggest what it needs for the proper formation of the fetus, so women note a change in taste preferences. They may be attracted to those foods that before pregnancy seemed tasteless to them, and previously favorite dishes cause disgust.

Thirteenth day

Changes in the mammary glands begin to occur immediately after conception, in parallel with the processes taking place in the uterus. On the 13th day of pregnancy, a frequent sign of fertilization is discomfort in the mammary glands, and in some cases even slight discharge from them. The body is preparing for breastfeeding, the result of changes may be darkening and swelling of the areola around the nipples.

sixteenth day

From the 16th day of pregnancy, the neural plate is formed in the embryo, the ends of which are connected and form a tube. This is how the nervous system starts. After this, the skeletal system of the embryo is laid.

Conducting a test

How to find out if conception has occurred and whether pregnancy has occurred after ovulation? The accuracy of the test results depends on the time of the study. In order for him to fix the pregnancy before the onset of menstruation, it is necessary to purchase a test with high susceptibility. Some products are able to show the concentration of hCG starting from 10 mU / ml and fix fertilization already on the 10th day. The second type of test has less susceptibility and notes the presence of hCG only with 15-25 mU / ml, that is, after the first day of menstruation delay.

It often happens that conception occurs, but the test is negative. One of the reasons for this phenomenon may be the failure to follow the correct sequence of the test specified in the instructions. Also, the objectivity of the study can be affected by the use of excessive amounts of fluid and the test in the evening, which affects the concentration of the hormone in the urine.

If the second strip is poorly visualized, it is recommended to conduct a secondary test after a few days. Sometimes hCG rises slowly, and the test will fix a false negative result up to 3 weeks after the fusion of gametes. In this case, a woman can focus on subjective signs of pregnancy.

The issues of conception concern all women, regardless of whether they plan to have children or vice versa - they are afraid of an unwanted pregnancy. And if there was sex without using a contraceptive, the woman will be worried about the questions: “When can I find out if conception has occurred? How long does it take after intercourse to get pregnant? As a rule, this is 7-8 days after sex, and here's why.

How does fertilization happen?

The birth of a new life is a complex process, and in order for it to occur, it is necessary that all stages of fertilization be observed:

• ovulation (release of a mature egg);
• fertilization (penetration of the sperm into the structure of the egg);
• cell division (the fetal egg begins to divide into cells, creating the basis for the development of the embryo);
• implantation (fixation of a fertilized and cell division of the fetal egg on the uterine wall).

Ovulation

In the middle of the menstrual cycle, the ovarian follicle matures and the egg is released, which at this moment is ready to meet with the sperm. This readiness lasts from 12 to 36 hours (depending on the female body and on the totality of the influence of external factors such as nutrition, stress or climatic conditions).

If during this time the fusion with the sperm does not occur, then the cell dies and is expelled from the uterine cavity along with the menstrual blood.

Sometimes there is an almost simultaneous maturation of two eggs, and if both were fertilized, fraternal twins are born. Such a female feature of the body is hereditary.

There was an ejaculation after intercourse, and millions of tiny spermatozoa rushed to the goal - to the mature egg. But the path of a tiny cell is quite long, because in order for conception to occur, it must go through many obstacles in the female body:

• 1-3 cm of the vagina to penetrate the cervix;
• 2 cm of the uterine cervix;
• 5 cm from the cervix to the fallopian tube;
• 12 cm down the fallopian tube to the ovum released from the follicle.

The distance is indicated approximately, it can vary depending on the physiological characteristics of the body and on the time elapsed after intercourse, because the egg, after leaving the follicle, moves through the tube to the uterine cavity. On average, this distance is 17-20 cm.

But the male sex cells do not just have to go this distance, they pass it in the aggressive environment of the female organs, and the seminal fluid contained in the sperm, as a rule, ceases to protect them after passing through the cervix.

Many spermatozoa die after 2-3 hours (approximately the time required for male germ cells to make their way to the fallopian tube), the rest successfully reach their goal and meet the female germ cell ready for fertilization.

But you only need one sperm to conceive, right? This is true, and such a huge amount is needed because natural selection occurs, which contributes to the conception of a healthy child and the normal course of pregnancy:

• Weak cells die in the aggressive environment of the vagina, not reaching the fallopian tubes.
• More viable sperm under the influence of fluids in the body of a woman acquire mobility.

But when the spermatozoa reach the fetal egg, this does not mean that the conception has almost occurred and after that, after 9 months of pregnancy, the birth of a child can be expected. The egg is covered with a hard shell, and the spermatozoa, with the help of enzymes produced on their head, try to dissolve it. When this happens, only one mobile cell penetrates inside, after which the fertilized egg changes its chemical composition, making it impossible for enzymes to dissolve its membrane.

The process of conception itself is not fully understood. It is not known by what principle the sperm is selected, it is only known for certain that at this moment the sex of the child is laid, depending on which carrier enters the fetal egg:

• X chromosomes - a girl will be born.
• Y-chromosomes - you should expect the birth of a boy.

How long does it take for the egg and sperm to meet? From several hours to 1 day, and then the division process begins.

cell division

After the fusion of the male and female cells, a zygote is formed, which divides and turns into a fetal egg. A morula is created, the cells of which divide after every 12-15 hours.

Cell division by day goes like this:

• 1-2 day: the zygote divides into 2 cells - blastomeres. It is in the first days that a singleton or multiple pregnancy is laid. How many embryos will be in the zygote depends on the hereditary predisposition of one or both parents. After 2 days, the zygote blastomeres formed, it laid down how many embryos will develop, after which the next stage begins.
• Day 3 When the 3rd day comes, the zygote has 6-8 blastomeres, sometimes more (depending on how many embryos develop). After 3 days, the fertilized egg begins its movement through the tube.
• Day 4 Cell division continues, sometimes at this time the embryo attaches to the wall of the tube and an ectopic pregnancy occurs.
• Day 5 This is the time when the fertilized egg usually enters the uterine cavity, continuing to actively divide. In the uterine cavity, it moves freely, but can be fixed both after a few hours and after a couple of days. Which part of the uterine wall will be chosen, it is never possible to reliably predetermine.

After the 7th day, the embryo is already firmly entrenched with the help of the chorion (the rudiment of the placenta), where it will be for the next 9 months of pregnancy.

Fertilization of the egg after intercourse is not conception. Many different factors can affect the fact that an embryo that is not fixed or poorly fixed in the uterus may die. Therefore, the pregnancy countdown can be started from the 7th day after having sex, if in the future a pregnancy test confirmed the desired conception.
