I have been using the Mirena IUD now for 8 yrs (I'm on my second one) and it has worked awesome for me. No period,no cramps,no PMS. All of which I had in spades before I got it. I have a child but had a c section because of complications. The second IUD was a little tricky because the doctors inserting it didn't realize I had a short uterus??? I thought removing the first one would be bad but it was nothing. Good luck
