Okay so this dude who's been trying to get with me came over and needless to say we had sex. I thought I was fine since I thought I had just ended my period but it turns out I was in day 2 of my fertile window. We used a condom at first, then he took it off but he didn't ejaculate because I was bleeding from the sex. I was drinking that night and passed out and when I woke up he was gone... I'm kinda scared he might have done stuff to me while I was asleep. I was going to take plan b but I had taken it the previous month and I know it's not intended as a regular means of BC. I know my chances are low, but I'm kinda spooked.  Pls help.
