Gianvi
"My pharmacy switched me to Gianvi a little over a year ago from Yaz. I had no negative side effects on Yaz (it was also the first birth control I've ever taken). Since switching to Gianvi, I get severe headaches that lasts 1-2 days a week before my period starts, which force me to sleep in bed all day. My periods also start early, late, and trail on for a few days after they're usually supposed to end. My acne cleared up at first, but recently it's only my acne medication, Benza-Clin, that clears up my face. (Yaz did the opposite of everything Gianvi does, despite it being the "generic" equivalent). I'm switching to a new birth control this week. I'm going to try Beyaz."
