Drospirenone / ethinyl estradiol
"I would rate this above 10 if I could.  This is the best birth control I have ever taken.  I suffer from PMDD and my time of the month without yaz I feel like I could hurt people for no reason at all, just because I didn't like the way they looked at me or what ever. Anyways Yaz has helped that out so much.  My husband is so happy with the results.  I have had no weight gain, no cramping and only 3 day periods with very little bleeding and the best part is no irritability or major mood swings."
