Irregular Period! Wtf do I do?

Adriana

So I’ve had my period for 14 days already and it’s still heavy! I tempt to go through two-three tampons/pads everyday. Idk if you guys know what this can be or if I should go see a doctor. I’ve been on birth control before but it’s been a little under a year. Idk if me being on birth control at that time has anything to do with this
