Drospirenone / ethinyl estradiol
"I have been on Yaz for 2 and a half years and it's been the best form of contraceptive medication for me. I have tried other contraceptive pills and have had all kinds of bad side effects, but once I started Yaz I was fine. Originally I started using it as a form of contraception, I still do but it has also helped with my severe menstrual cramps and endometriosis. I can have my period every 3 months without a problem and I haven't experienced any side effects, pregnancy scares, bloating or acne on it so overall it's been great. "
