:-( , I have the birth control, mirena and have had it in for about 1 1/2 years now, I don't want to take it out because it is a great birth control..It's just one thing that has been bothering me since 1 month after I got it put in: I started gaining weight like crazy, I have gained 50 lbs. in 1 year. and still growing. What can I do? I have tried dieting and it does not help.
