Hotandbothered - My situation has a few similarities to yours. I am also 52 and had a Mirena coil for 17 years,am on my fourth one now. The main reason I had the Mirena was because of excessively heavy and painful periods. Contraception was a secondary consideration,as up until 4 years ago,my sex life was non-existent! The Mirena solved the period problems thankfully. When I had the last one put in (just under 4 years ago) I was told that when it was removed in July 2017,that it would be my last one as I would have gone through the menopause by then. So by rights,I must be actually going through the menopause/gone through the menopause by now. But I have no idea if I have! I have had absolutely no bleeding at all since the last Mirena was fitted
but with the previous ones I did have sporadic,light bleeding. So I don't know if the lack of bleeding is due to the menopause or a result of having the Mirena for so long. The ONLY menopausal symptoms I get is hot flushes now and again,and just a general feeling of being too warm a lot of the time. Apart from that,nothing. I did one of those menopause urine tests about 7 months ago,but it came up as negative.
. I asked my GP's advice shortly after that,and he said to wait until I have the Mirena removed next year then have a blood test as this would be he only way to confirm it. So another year of not knowing!
