"i&#039;m 26 and had it inserted in nov last year. the procedure was not painful but afterwards i had some cramping, but nothing i couldn&#039;t deal with. the first 6 weeks i had constant spotting and swelling. it got to a point where i had to go and get a sonar done, to find out whether it has moved (i went for a few jogs afterwards). well it didn&#039;t move at all. my husband does not even realize that i have it in. but my weight has been my biggest issue. i gained weight and i have been exercising more and eating healthier and my weight does not decrease. whether it is the mirena or maybe something else, i cannot be sure. but it started after the mirena was inserted. my mood swings are so much better and i just decided to even exercise harder."
