Drospirenone / ethinyl estradiol
"I've been on Yaz a year now and love it. I'll be honest, my first 2 months were difficult. Spotting, painful breasts, depression, exhaustion. But now I'm so glad I allowed time for my body to adjust. No mood swings or depression, my sex drive has increased, my skin looks great and my periods are highly predictable. I will always get it on a Tuesday night and lasts only 2-3 days with light spotting and very little cramping. I've also dropped a good 15lbs! My doctor said it's rare, but possible, to bleed every month and still be pregnant while on the pill. So I do take a pregnancy test every few months to be on the safe side since I rely on the pill as my only form of contraception and my periods are so light. For me that's the only drawback."
