I stopped taking this pill a couple of weeks ago because of nausea and breast soreness. The side effects started right away but since the pamphlet said they should subside within three months I tried to stick with it. The nausea wouldn't be so bad if I took the pill in the early evening but it was still bad. I lost my appetite and subsequently lost some weight ( I know - why complain about that). The breast tenderness got to the point where I was actually scared I was pregnant, that's how sore they were. Once I stopped the pill the side effects were gone within a week. Never again with Femcon.
