Currently on Evorel 75 and 200 utrogestan. I'm perimenopausal and using it sequentially. For various reasons I'm looking to reduce my dose to Evorel 50. How much progesterone do I need with this? I have Conti patches containing 170 micrograms of norethisthorone. Are these ok to use for 2 weeks followed by 2 weeks of the evorel 50? Presumably they would not be enough if I need to go back to the 75s? Any thoughts?
