I love Mirena! No more periods! I could not take birth control pills due to high blood pressuref and the iud was my chosen alternative. Due to nasty periods, my dr. recommended Mirena. I did cramp for about 2 days after insertion, but they told me to take ibuprofen right before the procedure (and I can't take ibuprofen), so if you can that will lessen it. At firt, as the lining of the uterus thins out I did bleed (not periods, just bleeding) for awhile, 6 months. Nothing too bad, it isn't like it was profuse. Worth it to not have periods for years to follow. I don't feel it at all. Make the choice that is right for you, Mirena is right for me. I'm older (40's), had my last child at 40, so I can't addres the issue of removal and getting pregnant again.
