I had n issue with my Mirena a few years back, the strings disappeared so I had an internal scan to find it. It was where it was supposed to be but they also discovered a few polyps as well.
I went into the woman’s clinic for my appointment, a female gynae and 2 nurses attended.
Wide awake, advised to take paracetamol and ibuprofen an hour before appointment.
You lay with stirrups, and they use loads of water to assist seeing things. My mirena was removed first. Then she did the polyps and took biopsies. I wasn’t in pain, but felt a bit bloated and stretched.
Took maybe 30 - 45 mins max. Sat up afterwards and stayed 20 mins to make sure I wasn’t dizzy or faint etc,
I walked to the car but wasn’t driving. Take a tena lady, you seem to leak for a while lol.
Honestly, I have health anxiety and it was ok. One of the nurses stayed head end with me for the whole thing chatting etc.
