No. In research where they put 50 women on the pill and 50 women not on the pill. The women on the pill LOST on average 1 pound. NOT a pound a week, NOT a pound a month, just 1 pound. I think this is b/c the women NOT on the pill have menses and they bloat up and bloat down and weigh 1 pound more b/c of bloat.
Some women experience the munchies with the pill and others do not. Each individual is different. If you think your pill is making you gain weight, then try a different formulation. There are like 7 different progesterones you can try and it might be the dose of estrogen, which can be lowered.
