menstrual disorders
"I have really bad cramps on my period and usually end up taking a day off of work each month. Since I've started Yaz I now have almost all the symptoms of PMS/PMDD which I hadn't had before. I had bad cramps and bloating for a couple of days during my period, sure, that's normal. But now I have mild cramps, bloating, headaches, irritability, muscle aches and trouble sleeping EVERY DAY since I've started! The doctor says it may take 3-6 months for my body to get used to the hormones but if this continues after 3 months I'm getting off them! The only bonus: my period is regular unlike before."
