Birth Control
"If I could give negative ratings I would. I have been on yaz for 4 months now and started it as a means of tracking my periods, which were irregular before. Much to my dismay yaz didn&#039;t help in this respect at all, I can&#039;t depend on it at all. My periods are still irregular. I have also experienced extreme mood swings, crying over nothing, getting depressed over silly things that never used to effect me at all. I have now stopped taking yaz and I&#039;m so much happier."
