Hi Deborah, yes that sounds exactly like me !
Started having the hot sweaty nights a few days before my normal monthly period last year, then the periods increased in frequency for about 6 months, to every 2 or 3 weeks, with the associated pre-period sweats at night only.
Then I had a few, very few, day flushes, which started in the stomach and spread up and down arms and nearly blew off the top of my head off and left me gasping like a fish on the shore ! Only lasted a minute but felt longer.
Then periods have sort of petered out, and so have the night and day flushes really, in both intensity and frequency.
Hope that helps !
I'm 52.
