"i have been on yaz for over a year now and i love it. i have not gained any weight. i don&#039;t feel moody or &#039;off&#039;. i actually feel great! i feel like my moods and pmdd are more under control then ever. i used to get very emotional while having my period and now i feel normal. i don&#039;t have cramps or feel tired while on my period and it is very light and last only 2 or 3 days!"
