L.F.
I just started taking Yaz a month ago and so far have had no problems. I used to have terrible mood swings, bloating and cramps, but I noticed I didn't have it this last month while on Yaz and my period was only 3 days. I also have had no weight gain or loss of libido. My doctor told me to give at least 3 or 4 months before deciding if I want to stay on it or not. I couldn't decide if I wanted to stay on birth control pills or use an IUD. So far, Yaz has worked pretty good for me. Good luck!
