so my boyfriend and I had sex last Sunday. I just got off my period the week before. We used a condom. As we were having sex I told him to stop for a second so he did.. but as he was pulling his dick out he said he felt the condom rip on the side. Now keep in mind he wasn't even close to finishing, and he NEVER comes close to finishing inside me. He always pulls out and then finishes in the condom. After that happened, I took a Plan B like 3 hours after just to be safe and make sure there's no chance I could be pregnant. Was the plan B even needed?? Should I be okay?? Please share your thoughts on my situation.
