Within my first 4 weeks of Yaz I had extreme thoughts of killing myself. I even came close to stepping out in front of a large bus on an avenue in my city. I called my gyno and she took me right off of it. It was my fourth birth control I've taken. I've tried Mircette since and had ZERO sex drive. Literally none (where as when I was on Lutera I actually became obsessed with sex and couldn't go a day without it). So now I'm on Femcon Fe. Hope it works well.
