So my boyfriend and I had sex Saturday. We didn't have access to condoms at that time, I thought it would fine since I take birth control pills regularly. An event occurred where I had to jump off of him and he came everywhere, I'm not sure how much he did inside of me. It wasn't until after that I found out I was behind on my pills by a day. I took the Friday pill and hours later I ate and  took the Saturday pill. I was scheduled to start my period Sunday and it hasn't come, today is Wednesday.
