I'm now on 275mcg of Estradot patches plus 6 pumps of Oestrogel each night. This gets me to between 650-850pmol. I am also on 500mcg of utrogestan vaginally, day 15-26. (300mg before bed and 200mg in the morning.) I need to test again this month to see if this is getting my progesterone levels up a bit higher, as on 300mg only (vaginally) it was in range but on the low side. Since I am taking a high estrogen dose, I take care to be sure I am getting enough progesterone as well. And I'm also on testosterone.
If you have thyroid antibodies, you probably should trial thyroid medication. Things will only get worse as your thyroid is further destroyed by the antibodies. I see Dr Momi from Functional Thyroid Care - he sees people online via Zoom so you can work with him anywhere in the UK. He prescribes levo but also T3 and he doesn't go by TSH but by your other levels. He's been my saviour. I am finally about right with the thyroid, on 75mcg T4 plus 30mcg T3 (split 10/10/10 - 3 doses each day). I have bloods in 2 weeks to check but, going by how I feel, I think I'm just about there.
The final thing to say is that I did my DNA via Ancestry. I mainly did it because thyroid people advised me to check and see if I had any relevant thyroid gene polymorphisms. You need to download the raw data after you've done the test, which is just a string of numbers and letters. It turns out I do indeed have the DIO2 conversion problematic gene, which means I can't convert T4 into T3 very well. This explains my low T3 and my previously high rT3. I feel like I have some evidence to show doctors in future, should it be questioned whether I need T3. BUT ALSO....
It turned out that I have SNPs that mean I don't convert beta carotene to vitamin A very well. I have a 69% reduction in ability to convert. PLUS, I have another SNP which causes low serum levels of vitamin A. All this means that I was very likely vitamin A deficient, especially given a rubbish diet most of my life. So I got some vitamin A and started taking it and I noticed an immediate improvement in sleep. I'd previously been too scared to take vitamin A as it's one you can overdose on, and end up with toxicity - so I needed the DNA test to encourage me to give it a go. ChatGPT gave me a list of neurological vitamin A deficiency symptoms which sounded very much like what I was experiencing. Which is all to say, if you are trying to plough through symptoms and casting a wide net, I do think the DNA stuff can throw up things that are useful to try. It's also not very expensive compared with 65000 blood tests....
