My fiance and I had sex the day that she forgot to take one of her active birth control pills. She took the missed pill the next day along with her next one as usual. The missed pill was day 15 of her packet. She had been taking them perfectly up until now as well. I understand that there is always a small chance of getting pregnant while on the pill but I was wondering how much her odds may have been increased. Also, should I be more worried about sex within the next seven days or is it the fact that we had sex on the day she missed a pill that I should be worried about?
