Hi Daftun - as Dancinggirl has said. The Mirena can stop periods well before menopause so the period you experienced is most likely because you are not post-menopausal. personally I would not be worried at all about this as it is less than a year after the Mirena was removed so would be classed as a normal period. It is bleeding after 12 months without a normal period that needs checking - and lack of periods on Mirena do not count as part of this. You might like to consider HRT as you are not yet at the average age of menopause of 51/52 so your bones and heart will get extra years of protection, and this will also help with vaginal/bladder symptoms - although local oestrogen is also the best way to target this area, often needed in addition to full HRT.
