Have you ever been diagnosed with PCOS or had any other ovarian cysts?

I would suggest going to the doctor (Maybe even an endocrinologist. My endocrinologist changed my life.) for a professional opinion. It may not be the birth control at all.

The only birth control that I am aware of that certainly causes weight gain is Depo-Provera (i.e., the shot). I've heard of people gaining 30-60 pounds easily on that.
