It is certainly possible that you're entering the next, and perhaps final phase, before your periods actually stop. It is a gradual thing, and you've already noted changes.
I just passed 10 months of no periods.
After being regular, for the most part, most of my adult life, things started to change about two years ago. I had several heavy, frequent periods, like 9 in a 5 or 6 month time frame (nothing like that had ever happened before). Then I skipped about three months altogether. Then over the following four months, I had either a heavy flow lasting a day or so followed by a little spotting or just spotting. Then, I had no periods for the next 3 months. Then one last period last May.
I've always been one who gets cold very easily. I like to be warm and even sleep in warm pjs pretty much year round. Well, that was until last year. Right before that last period, I started getting these internal hot flashes. Not the outright, visibly sweating or soaking wet kind that you sometimes hear about, but rather, I felt like I was being lit up from inside. Like someone flipped a switch and I automatically started boiling inside. The first couple of times, it was really unsettling, but once it dawned on me what was happening, I learned to let them pass by just breathing and going about my business. I found it made it worse when I announced to my husband or friends what was happening. Now, instead, I remain quiet and just remind myself that it will pass as quickly as it came, and so far, that has worked.
I'm hoping this is it for me. If I make it to May with no period, that will be one thing I can check off the list of things to worry about, although I realize the hot flashes can still continue.
Good luck and hope you'll be done with all of this soon.
---------ETA: Doris is right about the layers of clothes. That really helps with the hot flashes.
B! That's not what I wanted to read! You went nine months and then started again? Ugh. I'm so hoping I make it these next two months with nothing.
