Im bleeding?

So I'm currently ovulating, & my bf and I were getting intimate. He ended up fingering me, then basically fisted me. I came, then we noticed how wet I was... He went to the bathroom to wash up & the wetness was BLOOD! I rush to the bathroom & wipe... Yeah definitely a good amount of blood. I pee & it hurts! Wipe again & it's a strong tinge of blood. Not clotty or gushing. But its an alarming amount. Maybe he just scratched me inside?? Idk has this happened to anyone else?
