Drospirenone / ethinyl estradiol
"I have absolutely loved being on Yaz! I have taken every kind of birth control you can think of, and had terrible side effects. I have tried at least 5 different kinds of pills, the shot, an IUD. ( I'm also allergic to latex so yay for me). All gave me terrible mood swings, weight gain, and acne. Although, gaining weight when you only weigh 103 pounds shouldn't be an issue. It still bothered me enough to make me stop taking other things. With Yaz I had none of these side effects and felt better than before. "
