When planning a baby or choosing methods of contraception, the first thing to pay attention to is the calculation of the period of ovulation, when a mature egg leaves the ovary under the influence of hormones. Normally, this happens once a month, about two weeks before the onset of menstruation.

There are also cases that go beyond the norms when the eggs do not ripen or ovulation occurs twice within one month. In addition, the determination of ovulation is complicated by stress, overwork, colds and other diseases and hormonal disruptions.

This is worth remembering, especially when it comes to protection. Observing your body and knowing the physiological processes will help you avoid unwanted pregnancy and plan your life. Approximately calculate the time favorable for conception, you can:

  1. using an ovulation calculator;
  2. keeping a pregnancy planning calendar.

What indicators allow to draw a conclusion about reproductive health:

  • The length of the menstrual cycle. Normally, it lasts 25-35 days.
  • The regularity of menstruation. They come at regular intervals, without failures, with deviations of no more than 3 days.
  • The duration of the withdrawals. In a healthy woman, menstruation lasts 3-7 days.

Based on these three parameters, using a calculator, you can calculate and mark potential days of conception on the calendar. To get the most complete picture, it is recommended to keep a conception calendar for several months. This will help the gynecologist to see deviations that indicate health problems and determine the tactics for further examinations.

Calculation of the ovulation period and fertile days

The calculation of ovulation is carried out independently using special online applications (calculators). All of them are made according to the same principle and make it possible to calculate:

  • approximate day of ovulation;
  • fertile period;
  • the time of the beginning of the next menstruation;
  • recommended times for ovulation and pregnancy tests.

As a result of automatic calculation, a table with marked fertile phases is formed. Consider how to determine ovulation at home.

By the method of the last menstruation

It should be remembered that this and other similar home methods do not take into account the characteristics of the body, so you should not trust them 100%. You can only get pregnant when the egg has matured and left the ovary. After that, within 24 hours, it retains its viability and remains suitable for fertilization.

How to determine ovulation using this method:

  1. measure the length of the cycle (for example, 30 days);
  2. mark 1 day of the last menstruation (for example, August 1);
  3. calculate the start date of the next menstruation (1 + 30 = August 31);
  4. calculate the days favorable for conception, counting from the date after the monthly 14 days (31 - 14 \u003d August 17).

Approximately 17.08 there will be a new ovulation. With a regular cycle, it occurs 14 days before the onset of menstruation, and the duration of the cycle does not play a special role. That is, the length of phase 1 is individual for each healthy woman, but phase 2 is approximately the same for everyone.

The ideal period for conception is 4 days before this date and 4 after. In our example - from 13 to 21 August. The method of identifying the possibility of conceiving a child, based on calculations after the last menstruation, is informative only for healthy women. For greater accuracy, it is better to use it in conjunction with other means.

according to the calendar method

The calendar method is one of the most common and affordable ways to plan a future pregnancy. It is more accurate than the previous one, since several cycles are taken into account. It is recommended to calculate the data for the last 4-6 months or even for a year.

The calculation is carried out according to the following algorithm:

  1. select the longest and shortest cycle for the entire calendaring period (for example, 26 and 35 days);
  2. determine the moment of the beginning of the fertile period by subtracting 18 from the length of the short cycle (26 - 18 = 8);
  3. calculate the end time of the best period for conception, subtracting 11 from the long cycle (35 - 11 = 24);
  4. mark favorable days for conception as a segment between the numbers obtained, that is, according to our example, between 8 and 24 days of the cycle.

A correctly calculated period of time (about two weeks) in this way is the most promising in terms of pregnancy. The chances of conceiving in these weeks are 50-70% higher.

This method is easy to use, but it is only effective for regular menstruation. If over the past six months a woman has noticed frequent failures, delays or other changes in the cycle, then it is better to use alternative methods, after consulting with a doctor.

Features of the calculation for an irregular cycle

An irregular cycle is evidence of disorders in the body associated not only with the reproductive system. If such a problem is identified, the doctor may recommend tracking ovulation or determining the reasons for its absence in more informative ways, such as:

  1. Basal temperature tracking. The basis of the method is the daily rectal measurement of body temperature and entering the data obtained into a graph. When ovulation approaches, the temperature rises sharply by 0.2-0.4 degrees, and on the graph you can see a clear jump. From this moment, favorable days begin for the conception of a child.
  2. Using an ovulation test The test is done daily for a week before the possible onset of ovulation. The indicator reacts to the growth of LH in the urine, and the strips become bright. Over the next few days, the chance of pregnancy will increase.
  3. The level of vaginal discharge. Estrogen affects the abundance and consistency of secreted mucus. How to recognize ovulation in this case? The concentration of hormones increases to the maximum when the ovulation stage approaches, and a woman may notice that the amount of secretions has increased.
  4. Ultrasound diagnostics. Folliculometry is the most reliable way to study the work of the ovaries, helping to check the capabilities of the reproductive system.

The female body is unpredictable, so none of the methods described can guarantee an accurate determination. If a woman cannot recognize the signs of impending ovulation in herself and she fails to get pregnant within a year, especially if she has irregular periods, you should definitely visit a gynecologist to rule out pathologies.

Is it possible to predict the gender of a child?

Future parents are wondering if it is possible to somehow plan the gender of the child? There are many calculation methods on the Internet (planning calendars, floor tables, etc.). All of them are subjective and do not guarantee an accurate result.

However, it is still possible to slightly influence the birth of a child of a certain gender. To do this, you need to create certain conditions in the body. For example, Y-spermatozoa, necessary for the conception of a boy, are more mobile, fast, but do not live long. Therefore, the ideal period for such cells will be the period immediately after the rupture of the follicle and the release of the egg. That is, after ovulation, the likelihood of becoming pregnant with a boy will be higher.

X-spermatozoa, which determine the sex of a girl, live longer, but move more slowly than their counterparts. Therefore, to conceive a girl, it is necessary that they enter the female body 1-2 days before the onset of ovulation. Due to their high survival rate, they will be able to wait for the egg and fertilize it with a higher probability than Y-cells.

An ovulation calculator is one of the ways to determine the most favorable days for conceiving a child. After all, it is not always easy for even an absolutely healthy couple to conceive a child, if you don’t “get” on a favorable day, then pregnancy will not occur. Someone is more lucky and pregnancy occurs quickly, while someone has to wait for several months. Our ovulation and conception calculator will help you calculate that exact time.

But keep in mind that the results obtained may not be entirely reliable. The female body is very mysterious, and sometimes phenomena that are not entirely clear to medicine occur in it. For example, ovulation can happen towards the end of the menstrual cycle, or vice versa in its first third (whereas it should be exactly in the middle). On the Internet, there are often stories of women who claim to have become pregnant on absolutely safe days in terms of probable conception. So, an online ovulation calculator should not be considered as an independent means of contraception. It is useful as an additional tool for some categories of women.

As you know, today the most effective, effective means of contraception are combined hormonal pills and the Mirena spiral. But, hormonal contraceptives, unfortunately, have a lot of contraindications and side effects. And not all healthy women are recommended to take them ... For example, if a lady has only one healthy sexual partner, but her sex life is not regular - 1-2 times a month, or even less often, then you can use safer methods - spermicides, and on dangerous days, as an addition - also with condoms. Dangerous days can be determined by doing some calculations. You need to know the length of your menstrual cycle. Moreover, if it is irregular, then it is necessary to first calculate the average value, taking the last 6-12 months as a basis. Next, we calculate exactly the middle of the cycle. This way we get the approximate day of ovulation. We add a week before and a week after - the so-called dangerous time. Thus, half of the month is “dangerous” for a woman, and half is relatively “safe”. If you don’t want to count on paper and trust software calculations more, our ovulation calculator is at your service - you can calculate favorable and unfavorable days for conception right now by entering some data.

Now about the more pleasant - about planning a pregnancy using an online calendar. Here, mistakes are no longer so terrible, even if they happen. With the help of the program presented on this page, you can calculate the most likely days for pregnancy. There are already 9 of these days, or even more! But with frequent sexual intercourse, the number of viable spermatozoa becomes less, which means that the chances of conception are less. Better save your strength. Therefore, we not only use the online ovulation calculator, but also practice the good old way - measuring basal temperature. If material possibilities allow, we buy tests to determine ovulation. The onset of ovulation is indicated by an increased (above 37 degrees) basal temperature (taking into account possible factors other than pregnancy that could give such a reaction) and a positive ovulation test. It is also possible to confirm the release of the egg from the ovary on an ultrasound examination. There are also subjective signs, such as an increase in sexual desire, pain in the lower abdomen or on the part of the ovary and fallopian tube involved in the process, the appearance of transparent, rather abundant vaginal discharge.

If you had only part of the evidence of ovulation, and conception did not occur - do not worry. According to statistics, a very small number of couples get pregnant in the first 1-3 months of trying. And doctors generally say that you need to start worrying if pregnancy does not occur for more than 10-12 months of sexual activity without contraception. The fact is that that very auspicious day does not happen every menstrual cycle - so, calculating ovulation calculator is only half the battle. Psychologists recommend that in order to achieve a quick result, simply relax and stop counting and calculating something, making love in certain positions and by the clock, etc. Stress has a too negative effect on our body. So, if you're in a hurry to become parents, just go on vacation and enjoy each other's company! And the printed ovulation and conception calculator will then become one of the pleasant reminders for you related to the planning period for the baby.

Calculating ovulation online is a simple, understandable and affordable method to help couples dreaming of a baby.

The ovulation calculator service shows the most suitable days for pregnancy. But there is a small nuance. This method will work for women who have a normal menstrual cycle and record their start and duration each month. It is these data (the beginning of menstruation, the duration of the cycle and the duration of menstruation) that must be entered into the calculator to calculate the most suitable time for conception.

To get the most accurate results, we must not forget about the characteristics of the body, as well as various factors that affect the maturation of the follicle.

When does pregnancy occur

Not every sexual contact without the use of contraceptives should lead to pregnancy. It is the right phase of the menstrual cycle that determines conception.

Physiological processes in the female body depend on the phase of the cycle. The hypothalamic-pituitary system is responsible for the work of the reproductive organs. Releasing hormones produced by the nuclei of the hypothalamus are responsible for the functioning of the pituitary gland. Gonadotropic hormones secreted under the action of releasing factors control cyclic changes in the organs of reproduction, including ovulation.

Ovulation occurs approximately in the middle of the cycle, the egg, after the rupture of a mature ovarian follicle, moves into the fallopian tube. Within a day, the egg can be fertilized. In order not to miss this moment, you can use the ovulation calendar.

There are three phases of the cycle:

  • follicular phase. It starts on the first day of menstruation and lasts an average of 14 days. It is characterized by an increase in the blood follicle-stimulating hormone FGS. It is he who regulates the maturation of the follicles. Subsequently, one dominant follicle remains, which is preparing for the transition to the next phase.
  • ovulatory phase. During this period, the follicle ruptures and the egg is released. That is, ovulation occurs. You can calculate this phase using the ovulation calendar.
  • luteal phase. Duration - from 13 to 14 days. It is characterized by the appearance of a corpus luteum that secretes estrogens. During this period, the uterus is ready for the implantation of a fertilized egg.

If conception does not occur, the corpus luteum ceases to perform its functions, as a result of which the endometrium exfoliates, menstruation begins. From this day on, the beginning of a new cycle is considered.

Reliability and benefits of ovulation calculation

What are the advantages of the calendar:

  • easy to use;
  • safe and fairly accurate method with a regular menstrual cycle;
  • fast result.

Important: Whether pregnancy occurs or not depends directly on the mobility and viability of spermatozoa. If sexual intercourse occurs too often, the relative number of spermatozoa in the semen decreases. Therefore, a couple who “strives” for conception with all their might should wait for a favorable time for conception, and thereby increase their chances.

An ovulation calendar also helps prevent unwanted pregnancies.

This method should not be used by women who have problems with the hormonal background and the regularity of the cycle. In this case, the results will not be reliable.

Other pregnancy planning methods

It is possible for a woman to become pregnant even after one sexual intercourse, but for most couples it is important to plan and prepare for pregnancy well in advance. In addition to the online calculator, there are other methods to determine the ovulatory period in a woman:

Body temperature measurement

Immediately after sleep and before the start of physical activity, the temperature is measured. Its indicators allow you to assess hormonal homeostasis. The onset of the ovulatory period is characterized by an increase in temperature by 0.25-0.5 degrees. This method requires constant monitoring, attention, and regular recording of temperature readings.

Functional Tests

These include:

  • Eye symptom. To determine the phase of the menstrual cycle at this stage, evaluate the degree of expansion of the external pharynx of the cervical canal. The maximum expansion indicates a favorable time for conception, and indicates that the concentration of estrogens is at its peak.
  • Evaluation of the viscosity of cervical mucus. The nature of the mucus changes under the influence of estrogen. During the ovulatory period, the maximum concentration of estrogens leads to the greatest viscosity of the mucus, which is seen when stretched (about 12 mm).
  • Ovulation test. Depends on the phase of the cycle and shows the level of luteinizing hormone (LH). The maximum value of LH is reached before ovulation.
  • Karyopyknotic index (KPI). A smear microscopy is done, and the ratio of pyknotic (keratinizing) cells to intermediate ones is revealed. The ovulatory period of CPI fluctuation is 60-80%.
  • Fern symptom. Examine cervical mucus on a glass slide under a microscope. When in contact with air, a pattern becomes visible, in the form of a fern branch. The most pronounced and clear pattern is noted precisely in the ovulatory period, when the amount of estrogen is maximum. If there is no characteristic pattern, estrogen deficiency is noted in the body.
  • Ultrasound examination (ultrasound). Allows you to evaluate the work of the ovaries and the size of the endometrium.

You can also determine whether ovulation has occurred or not by the following signs:

  • dull pain in the lower abdomen, sometimes localized on one side;
  • more liquid mucus from the cervical canal, for better penetration of spermatozoa into the uterine cavity;
  • increased sexual desire - the so-called reproductive instinct;
  • soft cervix, painful mammary glands;
  • changeable taste, improved sense of smell;
  • surge of energy and strength;
  • slight weight gain due to difficult fluid removal.

The most simple, convenient and free method of determining is a specially designed calculator. A woman does not have to visit a doctor regularly or look for an ovulation test, she just needs to enter the data online.

If we talk about the greatest reliability of the results, it is still better to undergo an ultrasound scan. During the study, the doctor will see the presence of a mature follicle and determine the beginning of the ovulatory period. Ultrasound is the best research method when planning a natural pregnancy, IVF, and when monitoring an existing one. It is recommended to carry out it several times after a certain period of time. If a woman does not have any pathologies, then an ovulation test can also determine the body's readiness for conception.

How to know if conception has occurred

Immediately after the fertilization of the egg in the female body, hormonal changes begin. Pregnancy may be suspected if the following signs are present:

  • pain in the lower abdomen, sometimes in the side;
  • breast augmentation and nipple halo;
  • pain when touching the chest;
  • small bleeding;
  • flatulence, toxicosis;
  • a slight increase in basal temperature.

Over time, all these symptoms become less pronounced or disappear.

The above signs cannot be called absolutely reliable. Often these same symptoms accompany problems with the organs of the abdominal cavity and small pelvis. Also, they can occur against the background of stress and anxiety associated with the absence of a long-awaited pregnancy.

Therefore, in order to find out whether pregnancy has really occurred or not, it is better for a woman to wait for the expected date of menstruation, and, if there is a delay, to conduct a regular pregnancy test at home. This test is virtually infallible.

If the result shows pregnancy, an ultrasound can be done after two weeks. During this period, the doctor will be able to detect the presence and number of embryos, determine the position of the fetal egg in the uterus, and viability.

Online calendar and contraception

This service will be useful for couples not only when planning a child, but also for preventing unwanted pregnancies. If pregnancy is not included in the plans, then it is worth protecting yourself for three days before the ovulatory period, and the same number of days after. This method is not 100% reliable, as there may be hormonal deviations and cycle disorders. It is more reliable to combine this method with other means of protection (condoms, hormonal contraceptives, intrauterine device).

If you feel good, are planning a pregnancy, but it still does not occur, do not despair. The specialists of the AltraVita clinic have been successfully dealing with problems with the onset of pregnancy for many years.

There is all the necessary equipment for a comprehensive examination, and you can apply for an examination and identify the reasons for the absence or failure of pregnancy. For each specific pair, a diagnostic scheme is developed, and recommendations are issued depending on the result.

Our reproductologists have extensive practical experience in the treatment of infertility associated with various causes. Phone numbers for appointments with a specialist can be found on the clinic's website.

Any symptoms can be decisive, so every little thing is important in the diagnosis. During the diagnosis, the doctor will be able to determine fertility (the body's ability to reproduce healthy offspring), and then, prescribe the appropriate therapy, the purpose of which will be to establish a normal cycle and reproductive function. The sooner the problem is identified, the sooner it will be resolved by gentle conservative methods. And if necessary, you can use assisted reproductive technologies.

The reproductive system of a woman works to prepare for conception, gestation and childbirth.

This is a complex process that involves the internal genital organs - the ovaries and uterus, as well as the endocrine system, led by the hypothalamus and the anterior pituitary gland. The most important thing happens in the ovaries - the maturation and release of the egg under the influence of follicle-stimulating and luteinizing hormone (FSH and LH).

When and how does ovulation occur?

The process of ovulation is the culmination of the complex work of all systems of the female body, aimed at procreation. The essence of the process is the release of the egg - oocyte - from the ovarian follicle.

Follicles are small vesicles of connective tissue that are contained in both ovaries from birth in every girl. With the onset of puberty, the monthly process of follicle growth begins, giving every woman the opportunity to become pregnant.

In healthy women, the release of the oocyte occurs in the middle of the menstrual cycle. If we take the standard 28-day cycle as an example, then the release of the egg occurs approximately 13-14 days after the first day of menstruation. If the cycle is 33-35 days, the timing changes accordingly.

How does the process of follicle maturation and ovulation occur:

  1. The follicle grows during the first half of the cycle under the influence of follicle-stimulating hormone. In the process of active growth, it produces a large amount of estrogen, which activates the pituitary gland.
  2. In the pituitary gland, the active formation of luteinizing hormone begins, whose concentration reaches a maximum to the so-called. ovulatory peak. Under the influence of LH in the follicle, the egg matures.
  3. During the ovulatory peak, the follicle vesicle, reaching a size of 2 cm, ruptures, the egg comes out of it and begins to move along the fallopian tube into the uterus towards the sperm.

The period of time from the ovulatory peak to the release of the egg takes up to 48 hours. After ovulation comes the so-called. postovulatory phase, in which the corpus luteum plays the main role, which is formed at the site of the bursting follicle. The corpus luteum produces the hormone progesterone, which stimulates the growth of the uterine endometrium in preparation for the implantation of a fertilized egg.

It is interesting! It is generally accepted that ovulation occurs in women steadily every month. But in fact, this is far from the case: during life there are menstrual cycles without ovulation, which does not affect the reproductive system of a woman and her fertility.

Why determine the days of ovulation

Ideally, every woman who has a regular sex life should know the time of the ovulatory phase. Monitoring the menstrual cycle is important both for planning a desired pregnancy and for preventing conception.

The calendar method of contraception is based on determining the days of ovulation, in which a woman should avoid sexual intercourse during the ovulatory peak, but is allowed to have intimate relationships on all other days of the menstrual cycle.

If a couple is having trouble conceiving, by calculating the ovulatory peak day, they will increase the chances of a successful pregnancy by having sexual intercourse during the woman's ovulatory peak.

How to calculate ovulation - proven methods

The most effective - with the help of special strips with an indicator, with the help of ultrasound, measuring basal temperature and observing your feelings.

Method 1: Test strips

Pharmacies sell special test strips. Like pregnancy tests that respond to human chorionic hormone (hCG) levels, ovulation test strips respond to elevated levels of luteinizing hormone (LH). The increase in LH concentration is determined using test strips using a daily portion of urine.

Method 2. Ultrasound

With the help of ultrasound, folliculometry is performed - measuring and monitoring the growth of follicles in the ovaries. Using transvaginal ultrasound, the gynecologist will determine the stage of maturation of the vesicle in the ovary, and also assess the condition of the endometrium of the uterus.

In combination, this allows you to establish the fact of the release of the egg, predict the timing of the ovulatory phase, or determine the causes of insufficient ovarian function.

Method 3. Basal body temperature (BT)

The method of determining ovulation by measuring basal temperature is used as an effective way to monitor ovarian function. BT also underlies the physiological method of contraception.

According to him, during ovulation in women, the basal temperature (BT) rises - the temperature in the rectum and vagina. During the growth of the follicle and the maturation of the egg, BT is kept within 36.6 degrees.

With the onset of the ovulatory peak, the temperature rises to 37.6 and persists throughout the first trimester of pregnancy. If fertilization does not occur, BBT decreases to normal values ​​after 24-48 hours.

Important! To correctly measure the basal temperature, you need to in the morning, without getting out of bed and without making sudden movements, insert the thermometer into the rectum or vagina for 10 minutes.

If you do this every day for several months (you can keep a special diary or chart with a schedule), you will set the features of the menstrual cycle for planning conception or preventing unwanted pregnancies.

Method 4. Sensations and selection

Theoretically, the work of the ovaries should not cause any discomfort and specific sensations in a woman. But gynecologists call several physiological signs of ovulation.

Some women who observe their well-being also highlight similar sensations and phenomena in the body:

  • discharge from the vagina of a brownish color due to the admixture of blood released during the rupture of the follicle;
  • pulling sensations in the lower abdomen in the region of the ovaries;
  • increased libido.

Method 5. Online calendar

Calculating the day of ovulation online is the same calendar method that is taken as the basis for the algorithm for calculating the day the egg is supposed to leave the ovary. The computer program simply calculates the middle of the cycle, based on the date of the last period and the length of the cycle. For the calculation, you need to enter the necessary data in the special fields.

Here you can watch a video about the available methods for determining ovulation in women:

Which method is the most accurate

Methods based on physical examination (ultrasound, measurement of basal temperature), as well as the use of urine for the test, are considered to be sufficiently reliable. In the first place in terms of accuracy is folliculometry, when a gynecologist assesses the condition of the ovaries and follicles.

Basal temperature is also considered an accurate way to determine ovulation, but on the condition that the woman does everything right. To verify this, you need to measure BT for at least three months: this is the only way you will see the overall picture of the cyclical increase in temperature.

Test strips using urine can be considered conditionally accurate, because. they respond to the concentration of luteinizing hormone. But different women have different physiological norms for the content of this hormone, as well as conditions caused by dysfunction of the ovaries or the hypothalamic-pituitary system.

The online calendar is a less accurate method because requires a stable cycle day to day. In women with irregular menstruation, it will not work, especially since in different circumstances and under the influence of various factors (stress, excitement), the release of the egg occurs earlier or later.

Observing physiological sensations to determine ovulation requires experience from a woman. She must monitor herself very carefully for many cycles in order to identify patterns and differences in the functioning of the reproductive system.

Discharges, pulling sensations in the abdomen and increased sexual desire must be interpreted in conjunction with other data (day of the cycle, hormonal levels).

Conclusion

For the desired conception, you need to plan your sex life during the so-called. ovulatory peak, when a mature follicle bursts in the ovary and an egg ready for fertilization comes out. The ovulatory peak is determined using ultrasound, test strips, basal temperature measurements and observation of physiological phenomena.

Many of the women are familiar with the concept of ovulation. Who does not know, ovulation is a relatively short time period at which the probability of fertilization reaches a peak. Calculating this gap is extremely important for couples trying to have a baby. But at the same time, even the most accurate calculations are not a 100% guarantee of conception.

So, ovulation is the period between the phases of the monthly cycle, lasting about two days. What is so special about this process that regularly occurs in the female body?

At ovulation, the egg (mature and formed) moves from the ovary to the uterus. If the egg is fertilized, it will attach to the walls of the uterus and begin to develop. Therefore, women trying to conceive need to make the right calculations. Pregnancy, as well as ovulation, in each case occurs differently, individually, because it depends mainly on the menstrual cycle. Consider how the duration of this cycle is calculated.

How long does menstruation last

Ideally, the cycle should consist of 28 days. Menstruation should be regular and last about 3-5 days, but in reality their duration can vary between 19-35, while the monthly cycle itself can take up to 9 days.

Menstruation is a complex process that is directly related to hormonal balance. The slightest balance changes, sudden jumps caused by bad environment, medication or stress, in any case, affect ovulation and the day of conception.

Basic calculation methods

There are many ways to calculate ovulation, but, alas, none of them can guarantee that on this day the egg will leave the follicle. The fact is that this process depends on a number of factors, including irregular critical days, various diets, hormonal failure, diseases, and so on.

  • test strips;
  • ultrasound examination;
  • basal (rectal) temperature;
  • sensations, secretions;
  • special online calendar d.

Let's take a closer look at each of the methods.

Method number 1. test strips

Now, to calculate the day of conception, you can use special test strips that can be purchased at any pharmacy. These strips are used in the same way as pregnancy tests and respond to luteinizing hormone, which appears 1-1.5 days before the egg leaves the follicle.

Note! If the cycle is regular, then the test should be done 17 days before the onset of menstruation, and if not, then it is unlikely that it will be possible to determine the period of ovulation using test strips, because the woman will not be able to find the right time for this.

In this case, it is better to resort to ultrasound.

Method number 2. ultrasound

Ultrasound allows you to accurately determine the time of release of the egg. In addition, this method is also suitable for women with irregular menstruation. Thanks to the study, it is possible to determine the development of the follicle, as well as find out exactly when the egg will leave it.

If the cycle is regular, then ultrasound should be done three to four days before the planned ovulation, and if not, then egg monitoring should begin four days after menstruation and be carried out every few days.

Method number 3. Basal body temperature (BT)

The lowest temperature in the human body is the basal temperature, which is observed during sleep. Its measurement makes it easy to determine ovulation, since the latter increases the performance by approximately ½ degree.

In different periods of the cycle, women have different temperature indicators. So, in the initial phase, BBT is quite low, the reason for which is the effect of estrogen. And such conditions are ideal for preparing the egg for fertilization. The average temperature at the initial stage varies between 36.3ᵒС and 36.5ᵒС, although it can vary in one direction or another by about 0.1ᵒС. But during the period of ovulation, this indicator rises and can range from 37.1ᵒС to 37.3ᵒС. This temperature will be kept until the most monthly. And if they have not started, and the temperature continues to stay at this mark for more than 18 days and without any delay, then the pregnancy has already begun.

Note! When measuring BBT, you need to follow a number of rules that allow you to calculate ovulation with the utmost accuracy.

  1. For all measurements, you need to use one mercury thermometer. It should always be kept at hand (preferably under the bed), because getting out of bed or sudden movements are unacceptable before measuring BBT.
  2. The procedure should be carried out every day at the same time - after waking up.
  3. The measurement process itself will not cause any difficulties: the thermometer is inserted into the rectum, after which you need to lie down quietly for five minutes. Then the received data fit into a special graph.

For the indicators to be reliable, BT should be measured only after a long (at least 6-hour) night's sleep. Distortion of indicators can happen not only if these rules are violated, but also under the influence of other factors - diseases, medication, evening sex, fatigue, alcohol consumption, etc. All this should also be indicated in the schedule.

Note! A correctly drawn up schedule will be able to show the absence of ovulation or its onset. If pregnancy planning occurs, then BT is measured during three to four cycles of menstruation. All this will determine the cherished day of ovulation.

Method number 4. Sensations and discharge

Sometimes the period of ovulation can be determined without resorting to any calculations. For some women, it is enough to listen to your body for this. During this period, you may experience:

  • short-term aching pain in the lower abdomen;
  • change in vaginal discharge (those become viscous and more abundant);
  • breast augmentation;
  • high sexual activity;
  • mood changes.

Discharge during the ovulatory period becomes abundant, transparent and viscous, reminiscent of the consistency of egg white

Method number 5. Online calendars

Today, on many resources, you can use special programs that allow you to determine the most favorable time for conception. These programs are based on the so-called calendar method in contraception. According to them, if the cycle of menstruation is normal, that is, it lasts 28 days, then 12-16 days from the beginning of menstruation are optimal.

To compile an individual ovulation calendar, enter the duration of your menstruation cycle (usually 28 or 29 days) and the exact date of the last menstruation in the required fields, and then click the "Calculate" button.

Do not forget that the beginning of the cycle can only be considered the first day of menstruation.

Video - How to calculate ovulation and the day of conception
