I have an irregular period. On June 10th, my boyfriend and I had sex. We used a condom and I took the pill 10 hours after we had sex to minimize any possibility of a pregnancy. Today, there are 31 days after my last period. Am I or am I not pregnant!?
Plan B is said to be 89% effective if taken within the 12 hours after sex. Less reliable than the regular birth control pills. It's efficacy is based on it being able to delay your ovulation. Do you know what day of your cycle it was when you had unprotected sex? Day 1 of your cycle is the first day of your period.
