"i used yaz before i quit to start a family. i used it for maybe two years with no negative side effects. i have used others in the past and hated them. with yaz i had clear skin, no mood swings, i loved it. about a year later i was losing weight. i was more skinny than i had ever been after high school. i can&#039;t wait to go back on it as soon as i am done breastfeeding."
