Suspected cervical polyp but mirena coil missing

Hi, 

I've been referred to see a gynaecologist (2 week wait) as I've had some bleeding, discharge and  twinges. I'm 46, perimoenopausal and on HRT. I saw a nurse today and she thinks that I have a polyp but the surrounding area is inflamed and very red. She asked another nurse to come in and have a look so alarm bells were ringing, by this point. In addition, neither of them could see the strings to my coil so that seems to have disappeared! I'm beside myself with worry, I'm trying to be rational about it all but my mind is in overdrive.

Has anyone else had something similar happen to them, especially with regards to a missing coil?

Thanks in advance,

LL
