A question about BC

Taylor

I've been on birth control for about 6 months now. It's usually pretty light, a new tampon every 4 hrs on a heavy day. But this month I'm bleeding heavier than normal and I've had really bad cramps. I've also found out that I have to have my gallbladder out because it isn't functioning. Does anyone relate or know what could be happening? Please no rude comments😊
