Help on an awkward sex issue?

Last Friday, I went to my first frat party at school and got really, really drunk (by mistake. I didn't plan on getting drunk). Let me also say that this is NOT me. I rarely party, have a 3.9 average and am a very good, honest girl. I had saw this guy, Devin, who I know through my Abnormal Psychology class that I've always had a secret crush on. He was pretty drunk too, and before I knew it, we were up in his room making out on the bed. At this point, I started to black out and don't remember much. But I know I lost my virginity to him that night. I don't know if he wore a condom, I am not on the pill, and don't have his number or last name to look him up. It is going to be so awkward to confront him in person before class on Friday. Any suggestions, please? I'm so nervous and need all the help I can get.
