Ok, so me and my girlfriend were fooling around and she started giving me a bj, but she says she didn't taste anything out of the ordinary (precum or cum). anyways, I was rubbing the head of my penis against her clit but I didn't precum and i had no cemen on my penis what so ever because I hadn't masturbated in the recent times and had a shower before I seen her (I also don't precum), But, it is time for her period and it is late and she still hasn't had it yet (2 days late) and we're scared there is a possibility she is pregnant. She is also new to being sexual active entirely so i was wonder, what is it that could have caused her period to be late, is it the very slim chance of her actually being pregnant, or just her hormones / it just being late and us being both paranoid. Btw, this Happened a week and 2 days ago from now.
