I had a Mirena coil fitted two weeks ago with the hope that it would sort out endo. After 9days of pain and cramping I had it checked - it fell out. I had a copper coil fitted the following day. I have had sharp cramping pains since then, and spent last night in horrific pain, where I could barely move (4days after fitting). I have been in some reasonable pain since last night, and I am concerned the threads have got longer since this. Am I just being paranoid or is it possible my body is rejecting this coil too? Feel at such a loss and I don't know what to do! Has anyone had a similar experience?
