period problems!

Darrian

I started birth control 3 weeks ago, and the lady said i needed to start it that day because my period was a week away. well, now my periods here and it’s been 12 days of nonstop heavy bleeding. is this normal? i’ve taken the pill at the same time every night (expect 2) and i thought it was supposed to help with it. i take the combination pill, if that’s helps.
