menstrual disorders
"I have been taking Yaz for 4 years, due to irregular cycle related to ovarian cysts.  I am pleased that my periods are shorter and there is absolutely no cramping.  It has helped alleviate hormonal migraines and my skin has never been more clear.  Prior to birth control, my cycle was completely irregular, such as skipping months altogether, and it was frustrating being so unpredictable.  Now, I know exactly when my period is coming.  The only  negatives: I did gain a little weight and it is expensive since I don't have insurance."
