"i have only had the mirena a couple of days but i really wanted to comment on the pain of insertion. although it is very very uncomfortable type of a feeling, it was not excruciating pain like some people had. i&#039;m 26, have had no kids, and am overweight (if that helps). it is over with fairly quickly, no longer than a minute or two. i felt some intense cramping and a couple of pinches of pain, but it the pain spread into just a bad cramp. just breathe and you&#039;ll be okay. i got this put in because i was sick of breakthrough bleeding on the pill. i wasn&#039;t on my normal period when i had it inserted, but i was bleeding a fair amount. this made insertion easier."
