Possible to be pregnant and have period on pill?

Miranda

Hey girls or guys, so my boyfriend came in me last Sunday and yesterday would've been a week since then. So I've been on the pill for about two years take it perfectly maybe late this month but no more than an hour or two other than that perfect. Anyways I started me break week and I am bleeding, does that mean I'm not pregnant should I still get a pregnancy test or? I heard if I was pregnant I wouldn't even receive withdrawal bleeding either. It's been a week now so idk if I could tell someone help please
