Hi, my periods, after coming off coc, then a brief try of Cerazette, and Femulen were:
9 weeks, 20days, 46,21,24,19,37,8,14,25,27,24,11,12,25,16 (spotting, 15(spotting),24(spotting), 11,38,27. Somewhere amongst that, I tried Norgeston for a week, and bled afterwards.
I found a paper on the internet, after much searching. It was trying to find a pattern of periods for perimenopause. I can't remember how many women they studied. The pattern that they came up with was: periods getting heavier and/or closer together, then lighter and missing some until they stopped. I can't remember the time period this was over, but probably 2-3years.
In actual fact, this was true for only 20% of the women they studied. There was such huge variation, that this was the nearest they got to an actual pattern. I didn't bother keeping a note of which paper it was.
So in the words of the locum I saw when I first started with this - anything goes in menopause.
