This is going to be a bit long but I really just want answers. Okay so the other day, Sunday at 1 AM to be exact me and my boyfriend had sex. It hurt and I bled a little but I wasn't a virgin and it had been 2 years since I'd had sex. This was weird because I didn't bleed the first time I ever had sex. Today, I went to the bathroom to poop and I noticed that blood was gushing from my vagina along with clots. I freaked out a little and tried to feel if I had scratched it or something but nothing. And my period doesnt come for another week or so. Before I had gone to the bathroom, I had and still have a bad stomach ache, I'm tired all of the time, nauseous and I get dizzy when I stand up. If it helps, I took Plan B 16 hours after we had sex. Could something be wrong up there or is it just the Plan B? Could I be pregnant?
