The pill

Hey y'all. So im.writing because I want to get on birth control. But it hear so many negative things about it. I have a very small build. I don't want to get on a birth control and gain a bunch of weight or get bad acne(which I hear happens alot). So what I'm looking for it advice on what birth control works but won't make me gain a ton of weight or have bad acne or anything like that?
