Any Idea what's wrong!??

So TMI but.. Me and my SO had sex lastnight. We went about 3 times, and this morning/all day my vagina was hurting like really bad. Usually I get sore from sex because we can get a little rough sometimes, but this was different. It almost feels like a burning sensation, like I have a cut down there or something? I busted out an ice pack earlier and that's the only thing that has helped the pain. I just don't know what's wrong... It hurts every time I move!! 
Any clue?? Please SOS!! 
XOXO,
Save my vagina❤️
