Hi there
Post-menopause used to be 2 years without periods if under 50 and 1 year if over 50. However this was changed so that everyone was considered to be post-menopause when 12 months had elapsed since last natural bleed. It followed that any bleed more than 12 months following the last natural period, was considered to be a post-menopausal bleed, at any age and should be investigated This was so that any potential cases of endometrial cancer or atypical hyperplasia were not missed due to the arbitrary definition.
It follows that there will be some women who do continue to ovulate more than 12 months after last natural period and then get a period.
As far as I know if you ovulate you will always bleed if not taking anything to stop it (but the converse is not true ie not all bleeding means you have ovulated), because oestrogen levels need to be very high for this to happen.
The egg-white mucus is a sign of high oestrogen so it could be your own + what you have added due to HRT?
The two years under 50 still applies to contraception, recognising that late ovulations are more likely to occur in younger age groups even after the 12 month time period since previous bleed.
