Help- super confused

Mads

I’ve been bleeding during and after sex lately (every time) and have no idea why. I’ve looked up reasons and a lot seem like they couldn’t really pertain to me. I’m thinking that it has something to do with the fact that I started birth control pills a few months ago. But I have no idea. And I’m starting to get superrr frustrated. Any advice ? Alsooo it’s not even just light bleeding. Its becoming heavier.
