Almost a 5week period!😩

I’ve been on my period for almost 5weeks now! I think it’s because of my birth control tbh. I got on the pill and I bled for 3weeks. So I switched to the shot. Now I’ve been bleeding going on 5weeks. It’s super super light though. I don’t know what to do🤦🏼‍♀️ should I wait it out and see if it regulates after a few months or is there something really wrong?! My boyfriend is super understanding but like I know this has to be stressing him out as much as it is me. Help!😂😭
