Frequent use of this contraceptive may have a negative impact on fertility and women's health in the future. Therefore, choose more for yourself safe ways protection against unwanted pregnancy, and resort to the help of postinor only as a last resort.

The principle of operation of postinor

Basics active substance drug - levonorgestrel. One postinor package contains two tablets, each of them contains 750 mcg of levonorgestrel. The first tablet is taken no later than 72 hours after unprotected act, and the second - 12 hours after the first was drunk.

Levonorgestrel inhibits the release of the egg from the ovary, therefore, its fertilization by sperm does not occur. That is why it is important to drink Postinor as quickly as possible, while the egg is not yet fertilized.

If a woman is still late in taking the drug and fertilization has already occurred, but ovum has not yet attached to the wall of the uterus, then contraceptive effect still persists (postinor will prevent the attachment of the fertilized egg). However, if the implementation has already occurred, then the pills will most likely have no effect. That is why it is necessary to take Postinor within the first 72 hours after the act.

Postinor and pregnancy

Despite the claims of many doctors that postinor is an almost 100% guarantee that there will be no pregnancy, statistical data suggests the opposite. According to statistics, pregnancy in women even after taking Postinor occurs in 10% of cases. What is this connected with? Probably, the reason lies in the individual characteristics of the body, or in the fact that the pill was taken too late, when the fertilized egg had already implanted into the wall of the uterus.

The reason for the lack of effect from postinor may be the simultaneous use of certain medications for the treatment of tuberculosis, epilepsy or fungal diseases. Taking medications containing St. John's wort together with postinor can also cause the tablet to not work properly.

If pregnancy does occur, you should definitely undergo an examination to identify possible pathologies in the fetus. Despite the horror stories told by some doctors that after postinoration a sick child may be born, there are many cases where children born after unsuccessful contraception were absolutely healthy, and the medicine did not affect them in any way. Leading experts have long come to the conclusion that postinor, for the most part, only prevents pregnancy, preventing the egg from being fertilized, but if this has already happened, then it will affect the fetus. negative influence does not provide.

To summarize, let's say that after postinor you can get pregnant in very exceptional cases, when its use was combined with the above medicines, or if the tablet was taken after the implantation of the fertilized egg into the uterus. In other cases, as a rule, unwanted pregnancy doesn't come.

Is postinor dangerous for health?

Some women do not use regular contraceptives, so if they are in danger of becoming pregnant, they resort to the help of postinor. If this happens once or twice, then there is no great danger to health, but frequently recurring similar situations are a reason to start sounding the alarm.

You should also remember that while taking postinor in a timely manner will protect you from unnecessary pregnancy, it will not protect you from diseases that can be transmitted sexually. Therefore, it is best to use regular condoms for protection.

How does postinor work?

The effect of postinor is due to levonorgestrel, which is contained in each tablet in the amount of 750 mcg. There are 2 tablets in total - one of them must be taken within 72 hours after unprotected sex, and the other - 12 hours after drinking the first.

Levonorgestrel contained in postinor prevents the release of the egg from the ovary, as well as its fertilization by sperm. If you take the pill late and fertilization has already occurred, then postinor may prevent the implantation of the fertilized egg into the walls of the uterus. However, if the implementation has already occurred, there will most likely be no effect from the use of postinor. This is why it is very important to take the first tablet as early as possible.

Pregnancy after taking Postinor

Doctors put the figure at 98-99%, but statistics show the opposite - for many, taking Postinor does not have the desired effect and pregnancy still occurs. Perhaps this is due to the individual characteristics of the woman’s body, or there were other factors that reduce the effectiveness of postinor - such as, for example, taking medications to treat epilepsy, tuberculosis or fungal diseases, as well as drugs that include St. John’s wort. If pregnancy has occurred, you must consult a doctor and undergo full examination to find out if there are any abnormalities in the health of the unborn baby.

Later, when it is possible to find out the sex of the child, it will also be possible to conduct a complete genetic testing to identify the slightest deviations. Although there are many frightening rumors that postinor has a negative effect on the baby, statistics again say the opposite. In most cases, after “failed birth control” with postinor, absolutely normal and healthy children are born. Leading experts in the field of gynecology claim that postinor only prevents pregnancy, but when it occurs, it does not have a negative effect on the fetus.

In any case, it is, of course, up to you to choose the method of protection. But remember that frequent use of postinor destroys your women's health, and may subsequently affect reproductive function. Well, to the question, is it possible to get pregnant after postinor, the answer is clear - it is possible, but in in rare cases. That's why the best option here you will choose a method of permanent contraception for yourself so as not to resort to such extreme measures, like taking postinor.

Most female representatives who know what Postinor is or have heard about it are wondering: is it possible to get pregnant after Postinor?

There are quite a few methods of contraception today. They different types, effectiveness and impact. But, as a rule, postinor is taken after unprotected sexual intercourse, when they increase.

Postinor is an aggressive emergency contraceptive. Without a doubt, it affects hormone levels.

This contraceptive is available in tablet form. You can purchase the drug at pharmacy kiosk. One package contains a blister with two tablets and each contains 0.75 ml of levonorgestrel.

The active substance levonorgestrel belongs to the group of gestagens. Gestagen is an active biological enzyme secreted by the ovaries. It affects the pituitary gland, provoking the release of releasing factors.

Levonorgestrel does not allow the release of a mature egg from the ovary, which is why fertilization does not occur. Therefore, it is important to take the first Postinor tablet as soon as possible, before the sperm merges with the egg.

The first Postinor tablet should be taken as quickly as possible immediately after sexual intercourse without protective equipment, but the period should not exceed 72 hours. The second one strictly after 12 hours after the first dose.

Also, if the period is slightly exceeded and fertilization has occurred, but the fertilized egg has not had time to implant into the mucous walls of the uterus, the effect of the tablets will remain. "Postinor" will actively help prevent egg implantation from occurring.

However, in the case when the fertilized egg has already attached, everything is there, it is hardly possible to do anything with the help of Postinor. That is why it is important to take the first emergency pill.

Depending on the phase of the menstrual cycle, Postinor can have the following effects:

1. It will slow down or completely block the release of the egg from the ovary in the first phase of the cycle, thereby preventing;
