Rough sex

May

So yesterday me and my boyfriend had sex 3 times.Every single time he went super hard and I could actually feel it in my lower stomach area.After we finished i peed and realized I was bleeding.I assumed it was because I just got off my period but today my stomach actually hurts.Is this because of the sex or it’s just period ending cramps? My period is fs over so I think he might have gone a little to hard and made me bleed.Why does this happen.Is this normal pls LML
