Confused

Ok so i just lost my virginity like 3 weeks ago and hadn't had my period (it was unprotected but was too painful so i made him stop before anything came out) WELL, today did it again. a lot. with and without protection BUT im on the pill and he felt like he was going to finish so he came out before getting super close to doing so. 
now i've been bleeding since like 1 (its 7:30 now) and idk if its my period or what???? help!!!!
