Hi Elaine
We are all a similar age on this thread, I think Sparkle is the youngest and I'm the oldest at 57 and it is utterly amazing that we seem to be experiencing almost the same things happening. None of our friends appear to have reached meno in the same way.
My peri has gone on since my early 40s (kill me!) and as I am really sensitive to hormone change, my records show a clear pattern of my reactions to changing hormone levels. Are you seeing changes in your mucus as that is an indicator of what your hormones are doing? We've all found that aside from the usual cervical mucus (slippery, fertile egg white type) that appears just before ovulation, if anovulatory it then reappears and goes on for lengthy periods of time. If this continues into a bleed or spotting it is an indication that it is an anovulatory bleed where the body is just clearing out any endometrial build up from the oestrogen highs. Therefore it may be that the light periods you are having are just slight anovulatory bleeds.
Unfortunately my oestrogen surges are usually through the roof and I seem pretty adept at shedding any buildup despite not having ovulated since last Oct. Machair and Sparkle are both having very very light spotting instead of a proper bleed now but my last bleed in June was like a light/medium period though only 2 days long, definitely anovulatory and I had gone 6 months without one.
Poor Sparkle has problems with her gut but I think Machair's and mine are only really affected by low progesterone, historically with a period bleed. I don't know whether you have read through this thread but you may find that you are in a similar situation and it may therefore be relevant for you.
Ask anything, we are usually around to support each other. It really helps to have someone to talk to about it, just makes you feel normal! (Well normal for us!) I think my poor husband could write a book with his knowledge of a woman's anatomy and hormonal responses!! Poor man!!
All good wishes to you.
