jobeckett - I said that you have been given the wrong prescription by the sound of it.
You either need to stick to the Evorel sequi (which is two weeks of Evorel 50 mcg followed by two weeks of Evorel conti which contains the progestogen), or you need to have Evorel 50 mcg together with the Progesterone - which for someone who is peri-menopausal should be 200mg x 11 or 12 days - at least to start with.
You do not need to go and spend £300 + with Prof Studd and you haven't been given a one-size fits all prescription. There are many different types of HRT and it is possible to adjust the doses as it is with private specialists.
You can change what you do without going back to your doctor but it would be sensible to go back to her to tell her you've looked into it and it looks like you've been given too much prog. Maybe she intended to give you Evorel 50 rather than sequi? Even so the Utrogestan should be taken for max 12 days only if taken on a cycle.
The only thing I can think of is that she is trying to lighten the bleeding but at what cost to your sanity?!
So it's your choice - but if you want to go down the separate oestrogen ( ie Evorel) and progesterone route - you will need another prescription because half the pack will be wasted. Just to be absolutely clear - you do have half the pack with Evorel conti patches in it?
Hope this helps and you find a way forward
