I'm one of the few with a bad experience. Very few people know this - I can't believe I'm sharing it here

I had the Mirena. No kids, was in a stable relationship (engaged!) and my doc really wanted to pull me off of pills to see if that was the problem with my weight gain. I had a *really* hard time with the insertion. It HURT (and I have a relatively high pain tolerance for such things). I had about 2 weeks of really heavy bleeding, and things calmed down for about 6 months. I have *never* had regular periods, so it was hard to tell if it was the IUD or the periodic 6 months with no period cycle.

On our wedding night, we notices something poking out. I spent the first day of my honeymoon getting the IUD removed (which did NOT hurt). It had turned around - the strings were no longer sticking out - one of the little arms was turned down and coming out. OUCH! The poor doc who removed it never even charged me My doc said not to try again with an IUD because it would likely happen again....apparently my body was very active in rejecting it.

So...it doesn't work for everyone...
