bid, you won't be menopausal yet, you're far too young!
Not necessarily. Bid could be going through the peri-menopause. That is the time that leads up to cessation of "periods".
I went into the peri menopause when I was 42 years old. For me, it started with subtle changes such as diminished libido, forgetfullness and my periods began to get lighter and shorter. I stopped menstruating when I was 47. No one is the same, we will have different symptoms as some will get "heavy and longer" with a libido they can't control !
The other thing to consider is that some autistic people may have Fragile X . One aspect of this condition is early menopause but if Bid is experiencing menopausal symptoms , I would say she is still within the normal range.
Bid, have you asked your mum when she went through her menopause, because they say that daughters tend to stop around the same time as their mothers. That was certainly true for me, as my mum ceased menstruating when she was 48yrs old.
