I have been in almost the identical situation to you recently.
Please see my thread called 'Still Regular Bleeds age 58'
https://www.menopausematters.co.uk/forum/index.php/topic,64739.0.html I too was having regular predicable bleeds of my own plus the utrogestan withdrawal bleeding - which caused me severe anaemia!
I was sent for a scan because I could NOT be POSSIBLY having my own periods at my age, - yet at the scan I was told my womb was indeed that of a still menstruating woman, that there were no abnormalities and my lining was thin, everything perfect.
Please try not to worry too much about your investigations, they will prob start with abdominal scan anyway, and it may show no further investigations needed.
I was put onto continuous 100mg Utrogestan 5 months ago and I'm STILL having my own regular bleeds with all the PMT beforehand. HRT apparently does not stop your own cycle.
I was offered Mirena but declined for 2 reasons - one was I have heard horrible stories about insertion and two - I am progesterone intolerant. Utrogestan is the only prog I can tolerate.
I've started a few threads lately about this, such as 'Is There An Age where the NHS Will Take you off HRT?' because the doctors scared me so much, and when all looked well, still spoke of taking me off HRT due to my age. Ridiculous as I need the HRT now given I haven't gone through menopause yet and my symptoms if not on HRT make me and my entire life unbearable. (And my husband's!
