Perhaps you have an infection, I don't mean to scare, it's just that you said the discharge was green, which suggests more than just mere irritation.
We have to get on the case with anything down below as it can turn nasty quickly. Again, I don't mean to scare.
I take vagifem, I believe it's similar to vagirux pessaries.
My Dr suggested prasterone.
I know it's the gold treatment, but it's expensive, my GP said primary care cannot prescribe, but I think that is not true. It might be my next move.
Biologically, there are receptors of testosterone and oestrogen down below, and while vaginal oestrogen is a godsend for this sort of thing for many, it stands to reason we need all hormones down there replacing topically.
I would speak to a GP, quick style, even if for peace of mind, as I am not a Dr.
Dr Louise Newson has loads of free education on this (and more) she's good while you wait to see your Dr.
