The main issue (in the UK) is that the NHS do not offer a wellness or therapeutic service. They offer the pill to prevent pregnancy and oestrogen for post menopause. The Utrogestan is available to protect the womb for those on ERT who still have a womb.
For perimenopause and those post hysterectomy, who both need progesterone therapeutically, to help with mood, sleep, anxiety etc. progesterone is unlicensed so has to be sought privately. I believe some NHS docs will twist the rules and I have been offered it because I was diagnosed with high oestrogen which has caused liver growths. This is where I think NICE are being ignorant as high oestrogen in peri can cause oestrogen driven breast cancer.
Like anything, it's about balance and whichever one you're low on, you'll feel better on it and worse on the opposite.
