Mirena and travels

I didn't even relate all these other side effects to my mirena (tiredness, acne, depression, joint & leg pain), so at least I have a clue where all that came from. My biggest problem with the mirena is that at my first checkup, the midwife couldn't find the string, so I had an ultrasound, which did not show it, and then an x-ray which did, but not in my uterus. It's off to the side somewhere, apparently perforated my uterus & travelled to somewhere inside my abdomen, where it is now going to have to be surgically removed, and who knows what other damage it has caused in its travels.
