What are the chances of pregnancy after having unprotected sex on 12 th day of the cycle cycle despite taking contraceptive

Hello,

Welcome to icliniq.com

I read your query and understand your concern. I do agree the sex was very close to ovulation or maybe right on the day of ovulation. But you have rightly taken the pill within 24 hours (the highest success rate of the pill if taken within 24 hours). So I do not see much of a chance of pregnancy. With your weight being slightly more than expected, I do not think your periods are regular, so ovulation is not occurring on time. In that case, pregnancy chances are even lower. The contraceptive pill has a high dose of Progesterone hormone, the same hormone which is produced in your body in the second half of the period after ovulation. This pill will suddenly increase the thickness of the inner lining of the uterus, making it unfavorable for a possible pregnancy to implant. As it is a single dose, it has no strength to stand on, so it falls off and you get period or bleeding of the increased thickness within seven to ten days of taking the pill. This bleeding will be thick, fleshy pieces, dark red or brown, with slight lower abdominal pain till the bleeding is really reduced. I hope I have clarified your query, do write back if any more queries

Thank you.
