A couple nights ago my boyfriend and I had sex. Before he went to finish I checked the condom was still on completely and it was, he went to finish and right when he did I knew something was wrong so I made him pull out. It was on my vaginal opening and then went all over the couch (a lot of it). I am on birth control and take it everyday just not at the exact same time everyday. The next morning, he went and bought me plan b and I took it. Should I be scared that u might be pregnant?
