Further update. I went to get my mirena taken out but the doctor couldn't find the threads, she fished about for a bit while I laid in agony, still couldn't find them. I was then given a scan and they couldn't see it on the scan so I was sent up for an x-ray. Thankfully it showed up on the xray, it has got lodged somewhere in my pelvis/groin. Been sent away to wait for the gyny to call me to get me in for surgery, she isn't there until Monday so I have to somehow get through the weekend, they didn't even give me any pain killers. Please let me know if you know of anyone who has experienced this. I do think I've just been unlucky with the whole mirena experience, sadly its not over yet though!
