I might sound really paranoid, but last night I was with this guy and we were fooling around. We were at a party and he started fingering me. I didn't think anything of it because I'm not a virgin and I've been fingered before. But I woke up this morning with blood in my underwear, I don't know if this is like what I've experienced before or if this is something different. Also, I don't start my period for another week. And I'm not scared as much as I am confused.
