"i&#039;ve had the mirena for a few months. the insertion wasn&#039;t uncomfortable at all. however, at first i bled for 3 months straight after insertion then one day it just stopped. then i got a light period for a week and a half the following months. i now have acne that i&#039;ve never had, the menstrual cycle lasts longer then it normally did, and i&#039;ve gained weight."
