I am 46 and had Mirena fitted in 2007. Apart from the initial setting in period I have been fine with the coil until may 09. I have constant terrible lower back pain. I have to wear a towel everyday and I have gone to no lose every month to back to losing heavily each month, which us what I had it fitted for in the first place. I was at the hospital last week and was told I have fibriods and that the consultant is going to remove the Mirena next week and put in a new one in. If after 6 months I am still having problems they are going to remove the lining of the womb. I am now wishing after many years of problem periods, wish they would just take the whole lot away because despite what they say, nothing seems to work and I suffering more and more the older I get.
