Drospirenone / ethinyl estradiol
"I have been on Gianvi around three years. I had always had extremely painful periods with clotting that would last 7 days since puberty, and really did not know how abnormal what I was experiencing was. Suddenly, in my mid twenties, I started having two periods a month, then they would last almost two weeks at a time. I was either having horrible pms or bleeding 100% of the time. Originally, dr had me on Apri. After 6 weeks of nonstop bleeding, dr switched to Yaz, which switched to Gianvi a few months later. The bleeding stopped, and each period got lighter and less painful. However, it did take two years for my periods to actually fall on inactive pill days."
