I dont know what happened 😳

ok so , me & my bf had sex & he noticed my wetness felt sticky . So he asked me if i was ok & i said yea so we continued then after we got done we noticed a puddle of blood under me , he gave me his shorts then i went to the bathroom . my lower stomach really hurts & we had sex alot in the last day really hard . he was in deep , which means he was in my stomach . it seems like my period on but its not due no time & before we had sex i wasnt discharging or cramping or spotting or nothing . later on that day i felt myself very lightheaded & tired & the pain in my lower stomach became more severe . he drove me home & we got out the car & i fell hard down on the street because of my lightheaded - ness . he picked me up & took me in the house , i was all bruised up & my stomach literally started becoming more painful , like contractions but idk if im pregnant . im confused .
