Just that really, have had a copper coil for the last 20+ years, but had to have it removed for a medical investigation. All AOK, but now I'm a bit thrown, I'd been told when the last one was installed that it could just stay in place.
Obviously, at 51 my risk of natural pregnancy is very low, but I would like it to be zero - I REALLY don't want to have a baby 
I had actually thought I'd been through menopause, but in the process of investigations as above I was told that my hormone levels suggested peri-menopause only. I've not been having regular periods - but then have had one recently - so if I did get pregnant I wouldn't know!
I've got a drs appt booked, but it's always nice to have a think about this & know what others are doing.
