Okay so Friday night/saturday mourning I was loaded drunk at a friends house with a few other friends who were also loaded out of there minds. One of my really close guy friends were there and long story short we ended up having sex. But the bad thing is.. we were SO drunk we didn't use anything, no condom no nothing. And on top of all that he was really rough and my vagina is so sore it hurts to pee. I also don't think he realizes we didn't use anything. When can I tell and find out when I'm pregnant? I need to asap!
