A couple days ago my boyfriend and I didn't completely have sex but this is what happened. We started to for like a few seconds no more than 5 and he wasn't even all the way inside me. We wer not using a condom so we stopped but he might have had precum yet. This was my first time and my hymen is still not broken but im still woried that I might get pregnant even if he wasn't all the way inside me and it was only pre cum. Can someone tell me if i could be pregnant and if I could what are the chances.
