I’ll share my story on the chance it might be useful.
I am 47 and in December (I was still 46 then) I had a period and not another until April. I have always been regular even through incredible stress, although the last two years my periods have been closer together. Ages 12–44 I was every month 26 or 28 days and then I went to sometimes being every 24 days in my mid 40’s, but still at time hitting the 26 even 28 day cycle, but rarely in the last few years. My periods became a day shorter and then two days-ish shorter.
My mom, when she was approaching menopause, missed her period for 9 months, had one more, and then never again. I thought maybe I would be similar to her, but I actually had a period both in April and May. We’ll see what happens going forward. I’m a little younger than I expected to actually stop my period in total, but it’s hard to predict. I have not had any hot flashes.
