I'm thinking about taking birth control, but I'm not sure on which one to take. I was reading about ortho tri cyclen lo but all does side affects about dark spots on face, blood spotting,dizziness and more. But the one I'm most worried is about weight gain. I already am having trouble losing weight I don't want this pill to make it even harder. I would really like to know what everyone opinion is about the birth control and also what ladies are on. I would greatly appriciate it.
