Ok here it goes...me and my boyfriend had sex a while ago, both of us losing our virginity. My period started November 15th, it ended on the 19th, and we had sex on the 23rd. We used a condom. The scary part is, he pulled out before he came. The condom stayed inside me. We checked it for holes by filling it with water, and it was fine. He definitely did not ejaculate inside me, I'm just worried pre-ejaculate could have gotten in me. So based on when we had sex in my cycle, and everything else i've explained, what are the chances i'm pregnant?
