Hey Stargazer
I think first I'd say please don't panic- it's VERY early days for you!!
Maybe you will need a bit more oestrogen or perhaps it's even a testosterone thing?? certainly us ladies who have had oophorectomy have our testosterone cut dramatically even if we're post meno- not sure it would affect you so soon, though, but might be wrong
I had ovaries removed November 2020 and, like you, was 1 year into menopause (2 years after last period)
I definitely felt different after but it's all been muddied by the fact that i've been coming off an antidepressant too- hard to know what's what!
for some reason I can no longer tolerate oestrogen- I was on it prior to the op but in all honesty wasn't tolerating it well then.
keep posting- you will get through this and if you need a bit more oestrogen then so be it
