"i have been taking yaz for a little less than a year, but i love it! i&#039;m 18 and a freshman in college, i barely ever have the side effects, and i can tell you when i will start my period pretty much down to the hour. i have suffered little weight gain (but then again, i&#039;m a freshman). i&#039;ve noticed that my side effects aren&#039;t as bad when i do daily exercise. i don&#039;t know if that has anything to do with it, but i love this pill and would recommend it for anyone!"
