Does Having Unprotected Sex During Periods Cause Pregnancy?

We had sex on 19th November and my partner took the p2 on 20th but not sure how she took it. And i shd point she was on her last days of menstral period so technicaly she was bleeding,we were intoxicated and the moment overtook us.She has not had he menses till now. How effective is it if both pills taken at the same time. Could she be pregnant and considering she was bleeding on the day we had sex? Thanks.

Hi,

Do not worry. Pregnancy is not possible because:

1. Sex was done on last day of menstrual period. It is completely safe period of cycle. During this period there is no ovulation and so no fertilization will occur.

2. You took p2 on 20th and it is highly effective in preventing pregnancy. It has 95-98% effective in preventing pregnancy. But pill can cause hormonal imbalance. It cause earlier period, intermenstrual period, delayed period by 1-2 week.

So do not worry of if period will delay by 1 to 2 week. If period will delay by more than 2 weeks then consult gynecologist for examination. Meanwhile avoid sex, Take healthy diet, drink plenty of water and do regular exercise.

Hope this may help you. Contact further if follow up needed.

Best regards,
Dr. Sagar
