I don't want to accuse him of rape but

I went out this weekend & got really drunk. I was with a small group of friends. I remember one of the guys helping me and cuddling me in bed but I also remember saying no sex cause I was on my period. We messed around but clothes stayed on and I was too drunk to give head or anything like that. I hardly remember the night, really. I don't remember falling asleep but obviously I did. I woke up feeling so disgusting, only one pant leg on & in a lot of pain. I thought the pant leg thing was weird so I went to the bathroom. I was bleeding & I know I had a tampon in the night before but it wasn't in when I woke up. I have bruises on my knees and hickies on my boobs. Only one side of my vagina is really sore & has a bruise. Do you think he fucked me in my sleep or was it me being really drunk but I don't remember? I would never want to accuse him cause he seems nice but I genuinely don't remember anything
