Weird peri menopause symptom?

[Stripyseagulls]

I am 46 and peri menopausal. One of the symptoms that I seem to have developed recently is being really horribly hungry and empty about 2-3 days after my period ends. It’s such an empty feeling that it’s like having really bad indigestion too & it’s like nothing fills me up- I have eaten loads today including eggs to fill me up.
But I feel dreadful still- hollow and empty with a knawing feeling inside.

It seems to happen every month a couple of days after my period has ended.

Aibu to think this is yet another weird mid life thing or something else?

Anaemia? I get like that occasionally. A good multi-vitamin seems to help, I take the women's 50+ chewable ones in a purple bottle.

Anaemia?
Like you I get the really empty feeling but about half an hour after eating breakfast. Like I've not eaten for weeks. I'm also bone crushingly tired.
