Hi Wenj27
Sounds like you weren't post-menopause when you started. The thing is at 54 it's not a question of we're all menopausal but apparently 80% of women are ( in the west) though of course many of us have no idea when we reach menopause, because once you start HRT you cannot be certain when your natural cycle stops! It's a good idea to have a rule of thumb like this though to ensure that those who need investigtion are not missed.
Sheila99 - I haven't heard of women in their 60's not having reached menopause - not sure if the research has been done - (though I haven't looked!) as it would need such women to have had a natural menopause and told their doctor. And as above it's important not to think a late menopause or an extremely rare very late menopause is normal even if it is, because it is at the limit of the normal distribution, and women need to go to the doc with bleeding that goes on into late 50s for example, especially if heavy, just to check all is OK. At some point a late menopause may actually become endometrial cancer so bleeding at 58 for example if it has been very sporadic, even in the absence of 12 months without bleeding, I feel should be queried, just in case. Nothing to lose! Not wanting to be alarming but wanting to make sure late (50's) (natural) bleeding is not dismissed, even though in most cases nothing will be amiss. Maybe I'm overcautious!
Sorry Wenj27 I digressed....
I'm also surprised that you were sent for a scan after only 6 weeks of continuous combined HRT. It could also be that your lining was thickened before you started the hRT because you are not yet menopausal and the 6 weeks of conti was not long enough to thin it down..
Keep us posted and all the best anyway
