Hi Jemima,
I am not sure about HRT stimulating anything in terms of pregnancy, but a woman is still treated as fertile for 2 years after her last natural period.
Also, there are a lot of instances where women on HRT still conceive, hence birth control needs to be in place and if conceived HRT must be stopped immediately.
Even at beginning of menopause (that's not peri) there are still eggs remaining that could potentially ovulate.
As the ladies said HRT hormonal dose is low in comparison to body's natural, however our own hormone production still continues as well...so I guess u never know.
The pill has different strength and type of hormones, the pill is given to women to override natural cycle, not to compliment.
This 'rests' our own bodies and ovaries.
There are new studies carried out especially for early menopause. They suggest that all young women should go on the pill.
I looked that up after I discovered that every lady who I know and who entered early meno seems to have that in common: not been on the pill!!! A very high coincidence if you ask me.
I also think that any question we have is worth asking and ALSO answering.
