Can I get pregnant?


Because I was going on a trip, I visited a doctor beforehand and received medication to delay my period (I took it until June 19).
I had intercourse once on June 17 without a condom, but there was no ejaculation inside.
However, since stopping the medication, my period still hasn't arrived.
Is it possible that I could be pregnant?

Hello, emergency contraception is not the same as birth control pills, and the chances of pregnancy are low.
However, it is best to take preventive measures beforehand and not rely on the calendar method.
If your period is more than a week late, it is advisable to see a gynecologist.
Wishing you good health.

When it comes to the possibility of pregnancy after taking delayed menstruation pills, it's important to understand how these medications work and the implications of unprotected intercourse. Delayed menstruation pills, often containing hormones such as progestin, are designed to postpone the onset of menstruation. They can be effective in delaying your period for a short time, but they do not provide contraception.

In your case, since you took the medication until June 19 and had unprotected intercourse on June 17, there is a possibility of pregnancy. Even though you did not ejaculate inside, pre-ejaculate fluid can contain sperm, which means that there is still a risk of conception. The fact that your period has not arrived yet could be a sign of pregnancy, but it could also be a result of the hormonal changes induced by the medication.

If you suspect you might be pregnant, the best course of action is to take a home pregnancy test. These tests are designed to detect the hormone hCG (human chorionic gonadotropin), which is produced shortly after a fertilized egg attaches to the uterine lining. For the most accurate results, it's advisable to wait until at least the first day of your missed period to take the test.

If the test is positive, it is essential to schedule an appointment with your healthcare provider to confirm the pregnancy and discuss your options moving forward. If the test is negative and your period still does not arrive, it would be wise to consult your doctor. There could be other reasons for the delay, such as stress, hormonal imbalances, or other health issues.

In summary, yes, it is possible to become pregnant after taking delayed menstruation pills, especially if you had unprotected intercourse shortly before stopping the medication. If you are concerned about the possibility of pregnancy, taking a home pregnancy test and consulting with your healthcare provider would be the best steps to take. Remember, understanding your body and the effects of medications is crucial for reproductive health, and open communication with your healthcare provider can help you navigate these concerns effectively.
