I have something that Yaz does..its kinda embarrassing but I know it has to be the Yaz. In November I noticed this funny discharge. It didn't smell. but I was wondering if it was a yeast but then I figured it might be the Yaz so I quit taking it and it went away. Well this month I decided to start taking the yaz again and sure enough my discharge is back. What is that? also I have chest pains, leg cramps, overwhelming nausea, brain fog, and breast tenderness. But unlike most the others it did help my sex drive which was very little, helped my PMDD, and periods became lighter. I also don't think I gained weight on that but I don't know. I have been craving a lot of sweets and am afraid to check my weight..lol.
