Hello. I’ve been taking birth control pills on time for 2 years and have always used condom whenever my partner and I have sex. BUT yesterday we had sex and we didn’t use condom for the first time. It was brief and he didn’t finish inside me. Should I worry? Is there a need to do Plan B? Also, I took the pill 12 minutes late the night prior to the intercourse. Is that considered late for the combination pill?
