bleeding but not period bleeding ???

Sav

so May 5th i had sex with no protection (rubber or birth control) he wasn’t inside for long, mostly because i’m still new at sex and he definitely didn’t cum inside of me. so fast-forward to two days ago, we started getting it on and he hadn’t cut his nails in awhile so we both thought he cut me. i go the bathroom and it’s a lot of blood, like not a lot like period but definitely a lot. also yesterday i’m supposed to be on my period but no more blood and even today. i’ve had cramps mall night and day. i’m just worried that i’m pregnant 😭
