The reason for the 12 months cut off for investigation of "post-menopausal bleeding" is a conservative one, to ensure that all women are investigated if they bleed after 12 months without a natural period, so that no potnetial cases of cancer are missed. It is not to say that having a period more than 12 months after going without one is anyway abnormal and likely to be cancer. As with everything there is a spectrum of times when women may ovulate after a long time without one and as a result of studies this has been set at 12 months.
From what I recall, the Stages of Reproductive Ageing Workshop (STRAW) referred to I think in a previous post, highlighted that in women with premature ovarian failure ie premature menopause, ovarian activity may be more likely to resume spontaneously than in older women - but the same 12 month cut-off for investigation stands.
I was responding to Uptick's post: my post-menopausal bleeds are perhaps less a cause of concern to the consultant I saw because they are responding to the HRT as 'periods' with the premenstrual symptoms associated with those, rather than there being something more sinister causing the bleeds.
I hope, anyway.
If you are on HRT then the term "post-menopausal bleeds" is actually not strictly accurate. If you are on cyclical HRT then a withdrawal bleed is normal. If you are on continuous combined HRT - this is designed as a no bleed regime but only if you are post-menopausal. Any woman who is post-menopausal and who does bleed beyond the 6 or so months settling in time after starting this type of HRT - should report this to the doctor, as well as any woman on conti HRT who has settled down and does not bleed - and then suddenly has a bleed. While likely to be due to an imbalance of progesterone/oestrogen due to the HRT, nevertheless it is as important to check as a genuine post-menopausal bleed.
It is absolutely crucial that any bleeding after 12 months without one, should be investigated in women not on HRT to rule out potential hyperplasia/cancer.
Bradenton - hopefully in your case it's a late ovulation (the lack of sweats are a bit of a give away - indoicating that maybe oestrogen was rising and you ovulated?) - all the best and let us know

I hope this is helpful.
