For a couple of years I was getting gradually less frequent periods, struggling with focus, sleep and motivation. I had a couple of months of really awful hot flushes, which coincided with when my periods seemed to stop altogether.
Then I seemed to get "myself" back, the flushes stopped and I thought it was all over. Yay.
Then, over Easter, I had my first period in nine months. An ordinary period, same amount of bleeding, same number of days as they always were.
Since then, the flushes are back and so are the problems with focus etc.
I'm 56, surely it should be done by now.
