I have to have Mirena fitted in a couple of weeks and am dreading it. It will be done at the consultant's clinic using ultrasound to check it's in properly. The last one 'disappeared' which now explains why I was feeling so awful and bleeding so much for the last few months. Seems it probably came out without me realising! The one before that was so lodged into my messed up uterus that it could barely be seen on ultra sound and then took ages to remove by hysteroscopy while I was under general anaesthetic. So even though the Mirena really helps to keep me going I haven't had the best of experiences putting them in or getting them out.
