Hi K.! I got the Mirena a year ago this month and it has worked excellent for me. I was told that there may be some cramping and a little pain after the procedure but i experienced no pain. I had a friend that had mild pain the day of and that was it. It is a painless precedure. You may feel a little pinch but nothing major. It has actually made my periods lighter too. I can only wear tampons for lite flow now too but the majority of the time i just wear pantyliners. Hope your results are as good as mine.
