I started YAZ in September of 2006. I went on it to moderate my moods before my period and help clear up acne (I had pretty bad cysts on my back consistently). I noticed that I lost my appetite and was nauseous for about 3 months, but that went away. YAZ was great in that my acne cleared up and I didn't feel so irritable before or during my period. However, my period actually became more erradic than it was before I started the pill—coming 2-7 before I started the placebo. My cramps were still severe, and they lasted a lot longer into my period. Painkillers didn't really seem to help like they did before I was on the pill. Bleeding was less though. By April 2007, I started bleeding and cramping in between periods. I finally got fed up (by this point I felt like I was ALWAYS having a period), went to my doctor today. He didn't seem too suprised at my problems and started me on Yasmin for the higher dosage of homones. Hopefully this will be better.
