Update - Just wanted to thank all you lovely ladies for helping me by 'listening' to me and replying in my time of need. You are all fabulous!
Went for an appt in response to our complaint letter.
Was surprised to find it was just a doctor and not practice Manager as we had expected.
I was all geared up to go into my complaint and then argue against needing a scan - - - but straightaway Dr told me she was happy to let me try 6 months on increased utrogestan (200mg) instead.
I am HAPPY with that, as that was my wish - but feel more anxiety after the event now because I have been worked up to fever pitch for 3 weeks.
I mean, WHY could that not have been suggested 3 weeks ago? I have been through hell!

I just didn't have the mental bandwidth to go through my complaint after that, and it was the same Dr so a bit hard to complain about a Dr when it was same Dr.
Anyway, I'm HAPPY, but also a bit let down at the same time? Makes sense?
I am trying to relax a bit now, but its hard, being wound up so long. i'm always like that after a period of stress - I get worse for a while AFTER it!? weird.
My periods ARE coming to an end, just had a very light 4 day period, so happy about that too, either its the increased utrogestan or a continuation of my own periods declining...
THANK YOU all once again for all your help . You really helped me through xxx
