"i am 26. i have two boys. i had no problems with mirena. easy enough procedure, usual spotting, then no periods. i loved it, until after 1 year i realized i gained like 30 lbs...*note* i did nothing i usually dont do...i ate the same...i exercised even more. i&#039;ve never been heavy, ever. now i&#039;m almost 200 lbs. that&#039;s the only problem i had. i got it taken out 1 month ago. if i don&#039;t lose my weight in 3-6 months i might put it back in and blame it on something else, but i doubt it."
