birth control
"I have used YAZ for a couple of days now...I'm not entirely sure, but I think I have PMDD. I usually have a super heavy periods that lasts 8 days. I did the Sunday starter and I had my period for only 4 days. I don't know how or why, but ever since I took the pill, I feel very happy and confident. I hope YAZ keeps this up in the months I plan to take it."
