Postinor in the first half of the cycle. Long periods - why? It is accepted in such circumstances as

Postinor is a drug that is used as a contraceptive in emergency situations, after completed intercourse. The effectiveness of the drug is quite high, however, there are side effects. It includes enough big portion hormones that cause AT similar situation it is worth taking a responsible approach to considering how menstruation can behave after Postinor.

The action of Postinor

If you still decide to use this drug, then first of all you should familiarize yourself with the principle of its action. To begin with, there are two main hormones that are unique to the fair sex: progesterone and estrogen. In a girl who does not have health problems, they are in harmony with each other throughout the entire menstrual cycle.

The composition of the tablets contains levonorgestrel, the principle of action of which is similar to progesterone. It is worth noting that its effect is almost 150 times stronger. In this regard, it is impossible to exclude the possibility of a failure during menstruation after taking this drug. Levonorgestrel is able to cause such reactions of the reproductive system:

Ovulation is delayed - the process of maturation of the egg is inhibited, as well as its exit from the ovary;
A hormonal surge quite often causes rejection of the endometrium;
Spermatozoa that enter the reproductive system of a girl lose their activity and ability to conceive.

Many believe that the use of this medication can cause a miscarriage. This opinion is erroneous. If the fertilized egg has already attached to the wall of the uterus and the development process has begun, then pregnancy is inevitable, and Postinor is useless in this case. It can only prevent conception, but does not terminate the pregnancy.

What is the effect of the drug on the course of the menstrual cycle? If Postinor acted at the right time, then the woman can only wait for the onset of the planned menstruation. If menstruation began after the medication, then the pregnancy was successfully prevented.

The change in the nature of menstruation is explained by the change hormonal balance woman's body. In some cases, changes may extend over several cycles. In this case, you need to seek help from a specialist, as this medication is considered difficult.

They are the reason that, as a result of exposure medicinal product the frequency of contractions of the walls of the uterus increases during menstruation.

Life doesn't always go smoothly and as planned. To mitigate the consequences of spontaneous sexual contact, a woman is sometimes forced to use emergency contraception.

What drug can be recommended today? The most proven is Postinor. It gives fast and reliable results. But there is a problem - menstruation after Postinor goes astray. This is because the body experiences a shake-up from a huge portion of the synthetic hormone contained in the tablets. Caused by this medication hormonal disbalance is the main and most negative consequence for the female body.

The principle and mechanism of action of the drug

In each period of the menstrual cycle, Postinor acts in various ways. Taking it in first half causes a violation of ovulation - the egg remains in the follicle (the process of its maturation is suspended).

In the second part of the cycle(after maturation) Postinor affects the structure of the mucosa, preventing the egg (already fertilized) from penetrating into the wall of the uterus.

In addition, the mucus in the cervix becomes thicker under the influence of levonorgestrel, and it is more difficult for sperm to enter the uterine cavity.

The drug interferes with ovulation or the conception of a child, and also interferes with implantation.

Basic rules of application

It is advisable to drink Postinor after an "unsuccessful" sexual contact in order to prevent an unplanned pregnancy.

The package contains two tablets. Both will have to be accepted. The first - during the day (then the probability contraceptive effect almost 100%). If you managed to drink the pill only on the second day, then the chance of not getting pregnant drops to 85%. On the third day, the probability will be already 50/50%.

The second pill should be taken 12 hours later, otherwise there will be no contraceptive effect.

This drug has contraindications and negative side effects:

Possible symptoms after taking the drug:

breathing difficulties;
repeated vomiting;
swelling on the face;
skin rash;
severe pain;
profuse bleeding.

If you experience severe side effects, you should immediately consult a doctor.

The correct reaction of the body to Postinor

A few hours or days after taking the drug, the woman should go bloody issues. They go with different intensity 3 or 5 days. This is a sign that pregnancy has not occurred (there has been a rejection from the surface of the uterus of the mucous membrane to which the embryo is usually attached). For a full guarantee, a control test must be carried out.

When the danger of an unplanned pregnancy receded, the problem comes to the fore: how to restore the body after Postinor?

When will the cycle return to its original state?

Regular monthly bleeding after Postinor should begin at the usual time. because of individual reaction of each organism for a “lethal” dose of hormones, it is not easy to wait for their onset. Some may have periods immediately and abundantly, while others will have to suffer in anticipation.

During this period, all women are very nervous and worried. How many days you have to wait, and when the cycle after taking Postinor is restored, not a single gynecologist will say. Sooner or later, menstruation comes. Anyway, in a few months healthy body recovers on its own.

If menstruation does not start

Delayed menstruation after taking Postinor - common occurrence. The hormones contained in the preparation have a very strong effect on reproductive system. A woman's body after such a hormonal shock can go on strike. If the expected menstruation after taking Postinor does not begin in any way, then this may have the following reasons:

Alcohol consumption. Is it possible to drink Postinor at the same time with strong alcoholic drinks? Acceptance of any hormonal drug gives heavy load on the liver, and additional exposure to this organ can lead to the development of toxic necrosis of hepatocytes and other fatal consequences.
Incorrect deadlines. Only by taking a pill within 3 days after an intimate relationship, you can count on positive result. Otherwise, the embryo will successfully attach to the uterus, and the pregnancy will develop. A delay in menstruation may indicate the completed conception of a child.
Preparations. Taking medicines such as HIV medicines peptic ulcer stomach, epilepsy, strong antibiotics, barbiturate-based drugs, can weaken the effects of Postinor and cause other negative effects.
The period of early puberty. At this age, the menstrual cycle and general hormonal background not stable. Their violation often ends with a long failure of the cycle, and bleeding can begin, which can only be stopped surgically.
Pregnancy. It is still possible with absolutely correct reception of Postinor. If after a month menstruation did not come, then there is a chance that the embryo managed to gain a foothold in the uterus. To check, you should do an analysis for hCG ( chorionic gonadotropin person). Reuse of Postinor in this situation is unacceptable.
Nausea, vomiting or diarrhea. These side effects weaken the effect of the drug as its concentration in the blood decreases.
Diseases of the liver and gallbladder. An organism weakened by these diseases can react not just with a delay in the menstrual cycle, but with an exacerbation of chronic diseases.

A fetus that has experienced a strong hormonal surge in the mother's body and is entrenched in the uterus is definitely healthy and viable. Active substance Postinora affects exclusively the activity of germ cells (male and female). Therefore, if after consulting a doctor there is no risk, and a decision is made to keep the child, then the woman can be sure that he will be born healthy.

When the delay in menstruation after Postinor is more than two weeks, then a visit to the gynecologist is inevitable. Only a doctor can figure out why menstruation does not start, exclude pregnancy and various pathologies caused by this drug.

Other deviations

Violations in the menstrual cycle are not limited to delaying the onset of bleeding. There are other signs of atypical behavior of the female reproductive system:

There are periods of an unusual dark brown hue in a smaller amount than usual. This phenomenon occurs frequently. Levonorgestrel has a thickening effect on the blood. It curls up and slowly leaves the vessels of the uterus. You should be worried if recovery does not occur in the following cycles.
Allocations for a period of 7 days or more are also common. This is affected by the day of the cycle on which the woman took the drug. If menstruation does not want to stop even on the 8th day, you need to see a doctor to rule out internal bleeding and learn how to recover from Postinor.
A large amount of discharge can also indicate pathological changes in the uterus. If the pad fills up more often than 2 hours, you should immediately go to the doctor.
If there is a delay after taking hormonal pills Postinor, and the test is negative, then hit on reproductive system turned out to be too strong. It remains only to wait for the body to recover from it.

You can take Postinor during menstruation. This will cause the cycle to pause for a few days and then continue. How after Postinor during menstruation? This issue will have to be resolved together with the gynecologist.

Why can't you take Postinor regularly?

If in a row vital reasons healthy woman took Postinor, then pathological changes will not occur in her body. But regular (more than 2 times a year) taking these pills leads to hormonal failure, causing infertility.

Carbohydrate-fat metabolism also suffers greatly from taking Postinor. A woman runs the risk of gaining a lot of weight.

The ovaries cease to function, become exhausted and fade away. Hormones are not produced in the right amount, which knocks down the menstrual cycle, and infertility may occur. Even treatment by a gynecologist will not restore the lost reproductive function.

Frequent thickening of blood in the vessels from the action of hormones additionally causes the formation of blood clots. With partial coverage circulatory system impaired blood and oxygen supply internal organs, and with a complete blockage, this can result in hemorrhage and a fatal stroke.

Planned pregnancy after emergency contraception

If everything went well - after Postinor menstruation went and regular cycle recovered, which means that in the distant future, no complications can be feared. 3-6 months after using the drug, a healthy woman can become pregnant and give birth to a desired and planned child. Ovulation occurs without problems after Postinor.

For this drug, all the necessary tests and trials have been carried out. It is officially approved and sold in pharmacies without a doctor's prescription.

Each emergency contraceptive, when used correctly, helps to avoid pregnancy, but it also causes harm to the body quite strong. Use it regularly - inflict one hormonal blow after another on your body. Before using Postinor as an ambulance for "bad" sexual intercourse, a woman should carefully weigh all the consequences and arguments for and against.

It has long been proven that none of the types of contraception used will give one hundred percent protection against unwanted pregnancy: the condom can break, and not on time taken pill, lead to conception.

Postinor - drug emergency contraception

If the probability of becoming pregnant is high, then in the first three days after unprotected intercourse, you can use the drug Postinor. It belongs to the group of emergency contraception. Its main purpose is to start menstruation. But the question often arises when menstruation will come after Postinor. Let's try to figure this out.

About the drug

With this drug, many are familiar firsthand. It prevents unwanted pregnancy and is a contraceptive. It is based on the hormone levonorgestrel. Postinor does not belong to the group of oral contraceptives that must be taken daily. it medicinal product which can help in some emergency situations. An example is the case when a condom bursts at the most inopportune moment.

One tablet of the drug contains almost twice as much levonorgestrel as the body normally produces. Less of it is contained in oral contraceptives for daily use. According to the instructions, you need to take two tablets within twelve hours. Large quantity taking the drug at a time will not affect the final result, but it can easily lead to hospitalization.

The action of Postinor is based on the fact that the body accumulates a large number of gestagen after its application. It is able to slow down the process of ovulation and lead to corresponding changes in the endometrial layer of the uterus. After using the drug, the attachment of a fertilized egg in the uterus is also impossible. The time of the arrival of menstruation is affected by the phase of the cycle in which the tablets were used.

In the case of sexual intercourse in the first half of the menstrual cycle, taking Postinor will have a blocking effect on the ovulation process, which will prevent conception. In the second half of the cycle, the action will be associated with a change in the uterine mucosa, which will make attachment of the egg impossible. In the first case, the action is associated with a decrease in the synthesis of estrogens, in the second - with a decrease in progesterone and luteinizing hormone.

Under the influence of levonorgestrel, the mucus in the cervical region becomes viscous and does not allow sperm to pass through. The probability of conception drops several times. For maximum effectiveness, the drug should be taken immediately after unprotected intercourse or in an unforeseen event. In advance, before the planned sex, such procedures are not recommended.

Postinor does not allow a fertilized egg to gain a foothold in the uterus

Correct Application

Tablets must be drunk no later than seventy-two hours after sexual intercourse with the outpouring of sperm, if pregnancy is not planned. Two tablets must be taken at least twelve hours apart and no more than sixteen. It is on how quickly they were drunk that the result of the onset of menstruation depends. Statistics show that conception will occur with a probability of:

5% - if you use the drug after twenty-four hours;
15% - if twenty-four to forty-eight hours have passed;
42% - if you take the pills after forty-eight hours.

When in the genital area a woman has no serious problems, then the arrival of menstruation after taking the drug is not delayed, they come on time. If they arrive one or two days later or earlier, then there is no cause for concern. If they are delayed for five days or more, there is a reason to conduct a pregnancy test or contact a gynecologist.

It is especially important not to forget that Postinor is approved for use at the age of sixteen years and older. It is not recommended for the category of women who have a strong hormonal imbalance.

More than once a month, Postinor should not be taken. And it is worth remembering that if the implantation of the embryo has already taken place, then this drug will not help here.

Over time, the effectiveness of the drug decreases.

In case of delay

Postinor, according to the instructions, leads to a failure of the menstrual cycle. Menstruation comes one, two days later or earlier than usual after using the drug. The next menstruation is also shifted by this period. The result of taking the pills is a weak spotting that lasts one or two days and resembles menstruation. They can repeat one more time in one cycle.

There can be several reasons for the late onset of menstruation:

pregnancy;
crash in hormonal system;
lack of a regular menstrual cycle;
infections in the genital area;
drug allergy.

Ovarian dysfunction recovers within two or three cycles. If the fourth and fifth periods in a row came late or did not come at all, then consultation with a specialist is required. At frequent use Postinor ovaries may not be able to cope with their intended purpose. The result can be infertility.

Only a doctor can help with pregnancy. The only thing that can be done at home is to conduct a pregnancy test. The final answer can be obtained after gynecological examination and taking an hCG test. If the results are positive, then there is no cause for concern in terms of the full development of the child. Postinor does not adversely affect the fetus and its full development.

Before using Postinor, you should take a pregnancy test.

Possible deviations

If a woman has an irregular menstrual cycle, hormonal disruptions, then some deviations are possible as a result of the use of Postinor for emergency contraception.

These include:

Profuse bleeding. Is the result of receipt powerful dose gestagens into the body, which causes a decrease in progesterone levels and pituitary hormones. Rejection of the mucous membrane in the uterus becomes the result hormonal changes, and bleeding occurs, which cannot be stopped on its own. If a woman changes two pads in a three-hour interval, then there is a reason to see a doctor.
Increased duration and intensity of bleeding. This problem typical for women with disruptions in the hormonal system. That is why it is not recommended to take this drug for this category of women.
Iron-deficiency anemia. Occurs as a result of heavy bleeding.
Painful and scanty menses. This deviation is quite rare.
Interruptions in the menstrual cycle. Occur in response to interruptions in the work of the pituitary gland or ovaries.
Allocations Brown color. They are quite an adequate response to taking pills.
Increased blood clotting. It occurs with repeated use of Postinor and threatens the formation of blood clots in the vessels, which can lead to a stroke or heart attack.

After taking the tablets, vomiting, swelling and pain in the chest, headaches are possible. Urgent help should be sought if there is shortness of breath, difficulty breathing, swelling of the face, unbearable pain in the lower abdomen and repeated vomiting.

Particular attention to the use of the drug should be paid to women with fibroids and other tumors in the gynecological field. Taking Postinor is also not recommended for those who smoke.

Postinor is recognized as a completely safe contraceptive that works well in unforeseen situations if you follow the instructions correctly and do not abuse it. Treatment after its use is prescribed only in cases where menstruation is delayed or does not come. And only when, after a thorough examination, the final cause is revealed.

Blood clotting when using Postinor can increase dramatically

But one of the main questions remains the one, the answer to which will be the period of onset of menstruation after taking the pills. As always, everything is individual and largely depends on the state of health in the female genital area. This drug tried on themselves thousands of women whom he helped to avoid conception.

Therefore, Postinor should not be considered a magical remedy for unwanted pregnancy and its use should not be abused.

A remedy for preventing unwanted pregnancy - Postinor, is known to many women firsthand. This is an emergency contraceptive drug that provokes hormonal failure. Therefore, the delay after Postinora or, conversely, unscheduled menstruation is a common thing.

The basis of the drug is large dose a synthetic hormone called levonorgestrel . Therefore, even one tablet causes not only a violation of the cycle, but also changes in the entire body of a woman.

Characteristic features of the drug

To understand how long the next regular discharge will come after taking Postinor, why there is no menstruation or it came too early, it is necessary to study the essence of the action of the remedy.

Efficiency

The action of the drug is aimed at suppressing ovulation. This makes it impossible for the cell to be fertilized when sexual intercourse has taken place. However, after Postinor, there is a strong shake-up and a cycle failure. No one can predict when the period will come. Maybe it will happen in a week, and sometimes it happens much later. Sometimes a pregnancy test shows a negative answer, but regular discharge does not all come.

Efficiency pharmaceutical agent guaranteed only if the first tablet is taken within the first 72 hours of unprotected intercourse.

In this case, Postinor will lead to the desired outcome in 80% of cases. If the woman took the medicine (the first pill) after two days, then her probability of not getting pregnant is 50%. After 72 hours, taking the drug will be useless.

The first tablet is drunk as soon as possible after intimate contact. The second should be drunk exactly 12 hours after the first.

The action of the drug

If there are no periods after Postinor for more than 2 weeks, you should consult a doctor, and after 5 days of delay, take a pregnancy test.

A negative result indicates that the drug has fulfilled its purpose, but serious complications could occur. The action of the tool is carried out in several directions:

Causes a delay in ovulation, due to which the female sex cell remains in the ovary. She cannot be fertilized.
After applying Postinor, the structure of the endometrium changes. The influence is directed to the functionality of the uterus. Changes in its ability to reject and build up the inner layer. When there is no menstruation and occurs slight delay, should be regarded as a normal occurrence in this case.

Thanks to these directions of action of the drug is achieved Great chance avoiding pregnancy. A test performed at home will confirm this.

Effect on the body

When the girl drank the required dose of Postinor, which the manufacturer indicated in the instructions, side effects may occur. The action of the drug causes diarrhea, headache, nausea. The most striking consequences are the failure of the cycle, hormonal disorders.

If there are no periods 5 days after their expected start, you must take a pregnancy test. However, if critical days did not come 2 weeks after application pharmaceutical product, you need to pay attention to the layer of the endometrium. After Postinor, various deviations in its development are possible.

Sometimes there are no periods long time. Even after a month, the normalization of the cycle sometimes does not occur. Therefore, it is necessary to take this remedy only in last resort. If menstruation does not start, you should immediately consult a doctor.

Contraindications

Not every woman is allowed to use Postinor. There is a group of people for whom taking the drug is contraindicated:

It is forbidden to prevent unwanted pregnancy with the help of the presented remedy for women whose menstrual cycle is irregular. The consequences of hormonal failure are extremely serious.

Therefore, you can use it only as a last resort, no more than once every six months. And it is better to never resort to such means at all.

Menstruation after drug use

Critical days after taking emergency remedy must go at their usual time. However, no doctor will answer how long to wait for this event. Due to the individual nature of the impact on the body, menstruation after the use of Postinor sometimes begins even after a few days.

it normal phenomenon, when a small amount bloody secretions. This phenomenon is called intermenstrual bleeding. It is caused by changes in the inner layer of the uterus.

If the menstruation did not go, they are all gone, although the test gave a negative result, then there was a hormonal failure and the restoration of the cycle sometimes takes quite a long time.

Prolonged absence of menstruation

After taking Postinor, sometimes there is no menstruation for a very long time. If regular allocations did not go in due time for them, this is due to a number of reasons. The main factors are the following:

Disorders in the female reproductive system. There is a serious hormonal failure.

In case of unusual copious discharge, you need to see a doctor. Perhaps there was an overdose or the drug adversely affected the endometrium of the uterus.

Effect on the fetus

If, after taking Postinor, pregnancy nevertheless occurred, then a series of examinations should be carried out. If the fetus is fixed on the wall of the uterus, survived the strongest hormonal shake-up of its mother's body, then it is likely that it develops normally.

A number of studies have confirmed that negative impact on the fetus pharmacological agent not not set .

The drug changes the structure of the endometrium and affects the degree of functionality of the egg, sperm. The child is born completely healthy. Therefore, if a woman has decided to endure and give birth to her baby, she may not worry about the correctness of his development after she takes Postinor.
