thank you very much too all the women that made post about yaz. I'm only 17 yrs old and im on yaz and i'd the same side effect i've had some hair lost and crying fits and breast pain . I thought I was losing my freaking mind, and this have been very scarey since this is my first birthcontrol. THANKS TO YOU ALL you have been so much help. I'm going to get off of yaz asap.
