Could this be a sex injury?

s

I had sex Wednesday last week. During foreplay the guy used his thumb on my clit and it kinda of hurt. He was a bit rough and it was really sensitive. (I like that ish) After a while I started to bleed from my vagina (start of my period). I could tell it was period blood cause of the uterine lining that was on his fingers LOL but since that day I’ve been in pain. Like it hurts to pee, stand up straight and it doesn’t feel like a burning sensation but more like a pinch. Can this happen? I tried checking to see if it looks weird but my stomach gets in the way. My mind goes straight to thinking that I have herpes…
