menstrual disorders
"I'm a teenager with a family history of endometriosis, and has had severe problems with my menstrual cycle. I have gone through many birth controls to find Yaz being the best at controlling all of my symptoms, as well as being an effective birth control. I have been on Yaz for two years, and just this summer, I was switched to Gianvi. My body is very touchy and picky about pills and did not react to Gianvi well, even though it was a switch that shouldn't have made a difference. It did not control my previous menstrual symptoms. I found out I had gotten pregnant, even with other contraceptives, and just went through a horrible miscarriage. If any other women out there have problems, I would recommend switching back to Yaz just from experience"
