I was on Yaz for aabout a year and a half. I moved to a new state and had to quit that and was on my period for 5 weeks. While on that period, I gained about 40 pounds. I got on a new birth control and absolutely cannot lose any weight. I've been exercising and eating healthier than I ever have before; I talked to my doctor and he said to watch what I eat. Well, I have, and nothing is happening. Any answers for my problem?
