Drospirenone / ethinyl estradiol
"I've been on Yaz for about 3 months and so far it has been great. I've suffered from acne since I was 12 (I'm 30 now) to the extent that it's really had a negative effect on my life but now it's almost all cleared up. I barely even need to wear makeup anymore. There has been no weight gain except for slightly bigger breasts and it's great knowing when my period is going to come. Previously it would come randomly. It also doesn't last as long, now only 4 or 5 days when before it could be 7 or 8."
