I agree with you Hurdity.
It would be an interesting experiment to see how it would feel to be on separate oestrogen 200mg patch with just 7 days of Utro.
I suspect it would make me feel almost permanently slightly stoned, as this is how I used to feel during ovulation before peri menopause started, and even once or twice during peri. It was an amazing feeling but you feel so blissfully happy and relaxed that nothing ever gets done.
On the BCP when I'm getting the good days I feel unusually contented and fulfilled, and even get an inordinate amount of pleasure from doing very mundane tasks like folding laundry

I'm aware that this is an un-natural mental state, albeit rather lovely, and can only think that somehow my body is producing a surge of its own oestrogen coupled with the high dose of oestrogen from the BCP creates this enormous sense of happy well being.
But everything I ever been told by GPs, and read myself, tells me that the BCP very effectively stops my own ovaries doing anything at all, so they can't be creating a surge of my own hormones???
