I've found this thread Machair.
I'm 56 and will be 57 next January.Last period 5 weeks ago very very light spotting. Before that erratic for 18 months longest gap 4 months. Dr thought I had post meno bleeding when my longest gap was only 9 weeks! So had to go through scan and biopsy. .All ok. I knew the bleeding I was having were periods as they felt like periods always had. I'd been to Dr with something else and the discussion just somehow arose. She's a lovely Dr and very thorough but a bit too hasty in this case. Obviously I was worried and it was a horrible few weeks.
Having meno symptoms. .hot flushes, not sleeping well, tired, no energy and little motivation at times, foggy brain, low mood and some anxiety although I have had health anxiety since my teens. My anxiety had been better but last few months seems to be a little worse.
Had a course of CBT which I did find very useful for health anxiety and some other issues concerning the mental health of my daughter...long story.
I do think a later meno fools me into thinking I'm younger than I am.
