I just want everyone to know I had a Mirena IUD for five years without any difficulty whatsoever! I'm a nurse and I honestly believe some people miraculously develop side effects only when they know what the side effects are 'supposed' to be.Be careful what you attribute to the IUD - they may not be related in any way, shape or form.
I loved my IUD and was totally suprised at how pain free it was to remove. I would definately recommend this form of birth control.
