Ok so last night me and my boyfriend were messing around and things got a little too heated and we sort of started to have sex. I say sort of because he didn't really get all the way in and it was only a couple of minutes before i freaked out and told him to stop. I wasn't sure if he had any pre-cum or anything when he was going in me so this morning about five and a half hours after we kind of had sex i got Plan B and took it. He didn't use a condom. I am on the tail ends of my period as well, as in I had I still was bleeding during the day and early evening before he started to go in me. I am so so so scared I could be pregnant...I can't stop worrying about it. Please help me...is it possible/very likely that I could get pregnant?
