Hi and welcome to MM kv
Were you told whether you are peri or post menopause? If you are post menopausal you shouldn't need progesterone.
It might be worth stopping the progesterone to see what happens before considering any form of treatment.
progesterone cream is unlikely to help flushes.
If you had problematic periods before, having a Mirena fitted and using seperate oestrogen as gel or patch would be the easiest way to have a good non bleed treatment for your meno symptoms.
