losing my virginity

Me and my S.O have tried to have sex and we thought maybe we have already stretched my hymen, but during those times he only went inside me maybe twice. The other night we had sex, and I bled so much. We both think he actually stretched my hymen fr this time, but it feels like now i’m just on my period? Friday I bled, Saturday I had cramps and all the other symptoms of my period, and today ( Sunday) i’m still bleeding. Can anyone shed any light on my situation? Is this normal or ?
