Hi I have been taking Yaz since August of 2007. I never connected any of my symptoms with my bc until I recently saw an advertisement on TV for a lawyer who is filing a class action law suit. I then begin to research side effects of Yaz and everything made sense. For the past 1 and 1/2 years I have been to doctor after doctor trying to find out what is wrong with me. It started with fatigue, muscle aches, and a fever that wouldn't go away. I was tested for every disease and problem in the book and sent to doctor after doctor and they never could find out what was wrong with me. Shortly after that in September of 2007 I developed chronic hives that they also couldn't find a reason for. When I asked my dr. if the Yaz could be causing the hives and other problems I was told that it wasn't possible. So I continued to take the Yaz and suffer. I continued to have more and more medical problems. My hair began falling out, I became depressed and tired all the time. I have gained 20 pounds during the time I have been on Yaz. I am only 30 years old and I have always been very healthy and active and been able to maintain a healthy weight with diet and exercise but since being on Yaz it doesn't seem to matter how little I eat or how often I exercise I continue to gain weight. I have been very frustrated. I have had my thyroid tested numerous times because according to my doctors that is what the symptoms that I have been having seem to be but those tests were always negative. I even had doctors and people I know suggest that it's in my head. I just stopped taking the Yaz and I am hopeful that my life will go back to normal. I am now on medication to control the hives and I am hopeful that they will go away once I have been off the Yaz for awhile.
