I had the Mirena IUD for 3 years. My husband and I thought we felt something during sex, so stopped until I could get in to have my Dr. take a look and see if the IUD was where it should be. I asked him to please remove it, regardless of where it was (right or wrong), as I didn't want to have any more worries about it. The Dr. couldn't find the threads to remove it there in his office, so told me to reschedule a new appointment in a few days to allow for more time for him to try and get it out with a hook to try and catch the IUD threads on the hook. He prescribed one Valium pill for me to take before this new appointment. He tried 4 times unsuccessfully to get to the threads that had gone back up inside of the Mirena IUD. Now, I needed to go get an ultrasound for him to make sure that the IUD was in fact in the correct place. I did this a few days later, and found that yes - the IUD was where it should be. So, the next step was to schedule an appointment at the hospital to have a D&C and Hysteroscopy so he could see what was going on and remove the IUD while watching the procedure on a monitor screen. My doctor suggested that it would be a good time to have a tubal ligation done in addition to this appointment. We've already had a child and are both 42 and are definitely done having children, so this was a no brainer. I had these two procedures done on Saturday (it's Monday now), and am so glad to know the IUD is out of me and that I don't have to worry about birth control any longer. I was put under for these procedures, and it was much less painful than the appointment with the hook in the office. I'm not bleeding today, and had light bleeding from the removal on the day of surgery and yesterday only. I really did like having the Mirena IUD. I only had light spotting, rather than heavy periods. The spotting would often last for 2 weeks sometimes though, so I never felt I could pin-point the start/end of a period. I don't think I noticed any hormonal imbalances over these 3 years, as others have posted. Still, I'm glad I tried it. I just wanted to point out that this problem with the threads going back inside of the IUD is more common than I knew. Not so fun to have it taken out the way it was for me.
