I am a 51 year old mother of 7 year old twins. One month after I stopped taking the pill, I gained 10 to 15 pounds. My doctor put me on bioidenticals. My main question is why I simply CANNOT lose this excess weight. I have never had a weight problem and exercise 5 to 6 days a week. I spend at least an hour a day at the gym, where I either lift weights, spin or jog. My diet is, and has always been, very good. Any suggestions?
