I found your post interesting Flo.
i too have been 'lied to' by my GP, you know, the people we are supposed to trust.
my surgery , (they said the whole of my NHS area but I do not believe them) stopped prescribing utrogestan because it was apparently SOOOOO dangerous for women, even though I explained it was the only progesterone I could tolerate because of progesterone intolerance to synthetic progesterones, and was continuing to be prescribed elsewhere they stuck to their script.
When we dared to ask, given that we had seen that it was so much more expensive than cheap harsh synthetic progesterones, if it was down to cost, we got NO NO NO, It's because it's DANGEROUS!!!

This was only a couple of years ago as well, meanwhile everyone else in nearby areas, all over Scotland were continuing to be prescribed it, let alone the rest of the UK and many parts of the rest of the entire WORLD.
Anyway they cut me off cold turkey. Because they wouldn't prescribe utrogestan they cut my estrogel too.
I had to buy it online at my own cost.
Shocking.
Because we complained to the practice manager about this I feel my surgery dislikes me now, paranoid? maybe, but that is how I am now made to feel. With good reason.
I have an awful relationship with my own GP surgery, just for trying to advocate for myself.
I am still having regular predictable periods and they have never stopped, but because I'm 61 - they flat out do not believe me, even though a scan 2 years ago proved it, that I was menstruating, and nothing has changed since still having periods that are getting lighter and hopefully moving towards finishing.
Meanwhile, I am being treated as a woman with post menopausal bleeding! Being sent for scans etc which I feel may not be necessary.
Consequently, I have zero trust or faith in my GP surgery
