Femcon FE and workout

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.

Well...I guess I'm not crazy. My doctor assured me this pill was great...I'm finding that not to be the case! I was put on Femcon FE following the birth of my second child via c-section. Since starting the pill I have experienced headaches, depression and MAJOR WEIGHT GAIN. Prior to the pill I was about 3lbs. away from my pre-pregnancy weight. After 6 weeks on the pill I have gained over 12lbs. It makes no sense. I am monitoring my caloric intake which is around 1500-1700 calories per day. I attend a tough "boot camp" style workout 4 days a weeks. How can I be gaining weight? I'm considering just going off birth control all together. I'm 39 and our family is complete. I just can't tolerate this much longer.
