I've had an iud for four 1/2 years and I'm due for it to be removed in april of 2011. I've had a lump above my belly button for just about four years. Sometimes it's visible, very visible or not visible at all, but i touch it and its always there. the pain ranges on a scale from 0-10. had the Mirena IUD for almost exactly one year and I had it removed three days ago, and I'm so happy I did! There was no pain at all during the removal process, it took all of 10 seconds and all I felt was a little pinch that was it. I would never recommend getting the IUD to anyone I know.
