I had my mirena coil fitted at my 8 week post-partum check after my second child, this was feb 07. I was breast feeding until july so didn't resume periods until last aug. When they did resume they were so heavy blood would drip onto the floor - and occurred every 2 weeks without fail. I was assured this would settle down, but by April this year I'd had enough. I was referred for a scan to check for cysts - nothing, then sent to a gynecologist who decided to remove the coil...except she couldn't find it. Another scan showed it was not there and I'd probably expelled it, but I had to have an abdominal x-ray just in case. Two weeks ago I finally got the results - my uterus has been perforated and the coil now lies in my abdominal cavity just near my left hip. I am in constant discomfort, and sometimes searing pain (I had to miss work today because the pain was so bad it made me sick) Yet I have to wait a full 2 months to have the operation under general anesthetic to remove the damn thing. I just want it out of me, and am unclear as to whether it can do any further damage. The consultant told me they can fit a new one whilst I'm under, but I'm having serious doubts as to whether I want another one. Interestingly I've steadily put on 4 - 5lbs since October but yet haven't changed my lifestyle at all.
