"i&#039;ve been on yaz for about 8 months now and i have not one thing bad to say about it. i&#039;ve lost 10 pounds on it, i no longer suffer from pmdd, my periods are short and regular, and it cures my headaches. i don&#039;t know how i&#039;d live without it. the only days that are hard are the days when i have to take the sugar pills- i love this birth control."
