I was on Femcon Fe for about 6 weeks and I was always tired. I gained weight while on this bc and had severe bloating. I run on the treadmill for 30 min a day and while on this bc I never had enough energy to workout at all. After I got off Femcon Fe I was peeing like crazy because while I was taking it no matter how much water I drank I would rarely pee. this bc made me retain water. It made my mouth very dry I had leg cramps and shortness of breath with chest pains.
