birth control
"Yaz is the WORST birth control I have ever been on!! Other birth controls would stop my period for like a month but then everything would straighten out and my period would be perfectly regular. I've been on Yaz for 4 or 5 months now, taking it at the same time every day and I never know when I'm gonna have my period or how long it's gonna be. I've been having a period every other week! That is not right!!! Also one period lasted 15 days. This is unacceptable. I am done taking Yaz. Will not recommend to anyone, ever."
