Hi matildamouse
It's impossible to advise if you are taking non-standard HRT ie the compounded bio-identical HRT which varies so much and is not recommended in UK (nor US come to that!).
It's not recommended in Australia either! You do have to ask yourself why it's so hard to find a doctor who prescribes it in Australia. It's because few doctors support it's use and those who do I'd be very skeptical of (rumours of kickbacks from compounding pharmacies etc). I actually had a couple of appointments with a GP who prescribed compounded hormones in Brisbane and he turned out to be the biggest scum on earth with the way he treated me (he claimed all my menopause symptoms were psychological etc). Have a look at this link from the Australian Menopause Society.
http://www.menopause.org.au/for-women/information-sheets/34-bioidentical-hormones-for-menopausal-symptomsI know exactly the phone company you are talking about matildamouse because I had a "consultation" with them when I started this meno journey, and I was appalled at the way they do things. Talking to a doctor over the phone, whose credentials you just have to hope are legitimate, and then working only on saliva tests, is not a good way to go about all this. Plus they are hideously expensive. It's a bit of a racket to cash in on all the untrue scare tactics women always have thrown at them about regulated HRT.
It is a myth that you can't get "bioidentical" estrogen (estradiol) from a regular doctor. It is readily available as patches, pills or gel, plus because it is covered by PBS the cost is less than $15 per month.
It is true that a regulated progesterone capsule (Utrogestan) isn't available in Australia, and I understand Australia's caution about approving it, although I won't go into that here because MM is very in favour of its use. However, the transdermal progesterone cream you are using is not proven to be safe if needed to oppose estrogen. (See the above link).
IMO you should put aside using this compounded hormone treatment and seek advice from a regular doctor, especially if you have a fibroid issue.
