Thank you so much for the welcome, and for the kind comments and advice.
I was writing in a rush yesterday and forgot to mention a couple of other things in my history which may be relevant.
I started menstruation very early (age 9!). Absolutely hated it then and all the years afterwards, too. I had bad period pain, totally unable to function without a lot of ibuprofen. So it was a huge relief to finally get suitable hormonal contraceptives in my 20s and not have periods. (Having to have progesterone bleeds on HRT has been a bit of a disappointment! Especially since I cannot now use a mooncup or tampons like I used to because it is too uncomfortable, so back on the old pads, which feel bulky and messy. But hey ho. I get cramping but nothing like as intense as I used to.)
I also don't have children (out of choice).
I understand both are possible factors in making early menopause more likely.
I have a family history of DVT (mother, when she was in her 40s) so that rules out some forms of hormones, I believe, but patches are considered safe?
At the most recent menopause clinic visit, I have also been referred for a bone density scan.
The pelvic pain - from what I am reading it seems similar to what is described as 'Protaglia fugax' - a cramping pain across the whole pelvic floor from tailbone to pubic bone, sometimes quite intense but comes on gradually and the lasts about 10-15 minutes. So I don't think it is bladder-related, and I have luckily not had any bladder issues so far. Pleased that whatever I am doing right with the diet is helping, though.
And yes, I had seen that Dr Newson blog about internal tremors and mentioned it during the recent consultation but I felt like there was a bit of a roll of the eyes ... is she not considered an authoritative source? Or is it just general contempt for people doing too much of their own research?

Thank you, I am a little concerned now that even the higher dose patch won't be enough. My next menopause clinic appointment isn't until January but could raise this question (and possibly the testosterone) with the GP in the meantime. My other hormone levels came up as:
Free Androgen 0.9
SHBG 97.4
Testosterone 0.9
Which all seem to be within the reference range given on the report, but I would appreciate any insight on these numbers.
Thanks again!
