menstrual disorders
"I was on Yaz for about 4 months. In the beginning, it was terrible.  I've never been so depressed, moody. I almost lost my fiancé because of it.  Even now, while I'm still on it, I cry often and feel depressed and insecure.  However, it didn't make me gain weight, which was my issue with other birth controls in the past. I just switched today to Reclepsin, so we'll see how it goes, but the SEVERITY of my depression on Yaz can't be stressed enough. It killed me! (And caused me to bleed out on my wedding, honeymoon, and for two weeks after... so much for sex, right?)"
