Hi dr. Is it okay if i take emergency pills like postinor-2 after unprotected sex during menstrual cycle? I am currently in day 4 and my period usually ends inconsistently on day 5-7. Does the effectiveness of the pill will decrease since I might be on my fertile phase? thanks in advance.

Hi, thank you for your questions.

You are looking for an answer regarding the effectiveness of emergency contraceptive pills taken during menstruation. We will try to help you

For your information, emergency contraceptive pills should be taken within 72 hours after unprotected sex. If taken outside this window time, it is not effective in preventing pregnancy anymore. Therefore, please always follow the instructions before taking any medication to get its maximum benefits.

Besides, you tell us that you had sex during your menstruation, which is when you are still bleeding. Ovulation or the release of the eggs happens usually during the middle of your cycle. Therefore it depends on how long your cycle is. One cycle is counted from the first day of a period to the last day before your next period. Sperm usually can live up to 3-5 days, therefore there are many factors to determine the possibility of you getting pregnant after unprotected sex.

We hope this explanation helps you.
Please talk to us via online consultation if you have more questions so we can help your further.
Thank you.
