birth control
"I was put on Yaz earlier this year by my regular doctor. Within a week of taking yaz, I had severe pain in my abdomen, I couldn't breathe without being in excruciating pain. A week later I was worse, I was in the worst pain I'd ever felt constantly. I went back to the Dr and after a week of testing and hundreds of dollars found out I have a Gall Bladder Infection and may have to have surgery to remove my gall bladder.  Luckily, medication cleared it up after a few days. Since then I have found out that there is actually a number of class actions, in a number of different countries including Australia & Canada, against the maker of Yaz due to the immense number of adversely effected women. Dont go near it!!"
