"i&#039;m 33 and just had my first my baby in september. 8 weeks after i had her i had the mirena inserted. when it was put in, i weighed 162 - i had lost 8 lbs after my daughter&#039;s birth. since then, in the last 5 months since having the mirena put in, i have not lost a single pound. not only am i breast feeding, but i&#039;m training for a marathon. i am eating about 1600 - 1800 calories per day (about 500 lower than my normal consumption while training for marathons) and i cannot lose the weight. 
has merina made me gain weight? no. but it is clearly a factor in not allowing me to lose baby weight. needless to say, i&#039;m going to have it removed. i believe there are better alternatives to something that keeps me 30lbs over my normal weight."
