Although it is rare; it is still possible to get pregnant when you are menstruating and you have an unprotected intercourse, especially when you have an irregular menstrual cycle or when the cycle is less than 28 days old.

In a regular cycle of 28 or 30 days, these chances are almost zero because, after the end of the menstrual period, there are still about 7 days until ovulation and the sperm survives, at most, 5 days inside the woman’s body, not even having contact with the released egg. In addition, even if fertilization occurred during menstruation, the uterus is no longer ready to receive the fertilized egg and, therefore, the chances of becoming pregnant are very low.

However, if unprotected intimate contact has occurred, the best way to confirm whether you are pregnant is to take the pharmacy test, which ought to be done from the first day of menstrual delay.

is it possible to become pregnant during a short or irregular menstrual cycle?

Contrary to what happens in a regular cycle of 28 or 30 days, ovulation in a shorter or irregular cycle can happen within 5 days after the end of menstruation. That is why there are greater chances of some sperm that survives and gets to the egg, leading to pregnancy.

So, ideally, women who have a short or irregular cycle should always use a contraceptive method, if they are not trying to get pregnant, even during menstruation.

What are the chances of getting pregnant before or after menstruation?

The chances of becoming pregnant are greater when unprotected intercourse occurs and, therefore, it is easier to get pregnant after menstruation. This is because the intimate contact occurs closer to ovulation and, thus, sperm can survive long enough to fertilize the egg.

If intimate contact occurs immediately before the menstrual period, the chances are also almost zero, being even lower than what happens when the woman is menstruating.
