Drospirenone / ethinyl estradiol
"I have been taking Yaz for a little less than a year, but I love it! I'm 18 and a freshman in college, I barely ever have the side effects, and I can tell you when I will start my period pretty much down to the hour. I have suffered little weight gain (but then again, I'm a freshman). I've noticed that my side effects aren't as bad when I do daily exercise. I don't know if that has anything to do with it, but I love this pill and would recommend it for anyone!"
