Hi can you still be perimenopausal at 59???
Yes.
They call it late onset menopause and it's more common than one might think.

As far as I can see, although interesting, I don't think these references actually address meenaruss's question - about menopause at age 59 and beyond.
Meenaruss - as with every condition there is a range and there will be individuals that fall at either end of the spectrum - so a few women/girls will experience very early menopause - sometimes even in their 20's and a few also in their late 50's. There are studies on this - but one I found you have to request full text and I haven't done that.
The most important points are that whilst it is within the range of normality to experience late menopause, the nearer to 60 you get, the more vigilant you need to be in relation to bleeds etc - and to report anything that seems very abnormal for you, unusaly pains, heavy bleeding etc - just in case there is an abnormal cause.
Some women develop fibroids as they age which respond to oestrogen and these can cause bleeding if they get to large. Also some women have endometriosis, polyps etc
Another point is that once you start HRT it is not possible at all to determine when you reach menopause because the HRT either overrides the cycle if peri-menopausal, or if post-meno can cause bleeding due to imbalance of oestrogen and progestyerone. The only way to determine this when on HRT (presumably) is to scan the ovaries I think and look at follicular count (?), possibly the hormone Anti Mullerian Hormone (AMH) - but this is not routinely measured and I'm not sure anyway what happens to this hormone once you start HRT.
Just realised that you had made other posts before the Q about peri-menopause....
"
Are you going to have the Essure coil removed?" Essure coil - this wasn't mentioned so no idea where that comment came from??
Meenaruss - you'll need to explain about this as it's not clear? Why don't you start a new post on a new thread and we can explore your situation more fully?
Like I said if you are on HRT there is no knowing when you become or became menopausal but an indication will be what your periods were doing when you started HRT and you age then.
If the HRT has caused the thickening then this just means that the balance between oestrogen and progesterone is not right and you need to make some adjustment. There is no need to stop if there is no good reason for this.
That said you could still be one of the outliers and have a natural period at 59 but this is not a likely explanation - but never say never!
Good to have hysteroscopy and biopsy to check all is well and check for any abnormalities which could be causing the thickening (other than HRT imbalance) - then take it from there.
Hope this helps
