SOS PLEASE HELP

My boyfriend and I have been having sex daily since Sunday.. I'm on the pill but last Wednesday I took it one hour and half later.. Next day I got my period and it's been a week now and I'm still bleeding.. Spotting to be exact. Last night he finished inside me and I'm scared cause I don't know if it's nothing to be worried or if it's because of the sex or because of the period. HELP ! opinions are appreciated .
