Turns out after a ct scan the orher day a coil that i had places in 20 years ago is in a place in my body called the pouch of douglas.. 20 years ago i had an ultrasound as doctor couldnt find threads and it didnt show up on scan so they assumed it had fallen out. Latley i have had blood in urine bad back so my doctor sent me for a ct acan. This is what showed up.. has anyone else had a migrated iud and if ao what ended up happening to yourself? I have been referred to gynaecology department so await their reply, will it need removing?
