what’s going on with my body ?!

Gabby

i just recently had gotten on the birth control pill, and my period came late this month, but my period is so much more heavier and it’s not just any type of blood, it’s all blood clots every time i go to change my pad. Plus, i’m suppose to be getting off my period by now, but it seems as if i’m not.. idk if i should go back to a doctor or just wait till it ends ?? pls help
