5mm is the highest they wish to see for women on vaginal or topical estrogens, as per my gyn. They used to say the 4mm but that changed the last time I spoke with her. Also the level of thickness is important, no humps or lumps that might indicate problems.

The estrogen stimulated would be from any biopsy done with a D&C.

You might do your own research on polyps and estrogen stimulation and see what you find.

Well, the vaginal progesterone is a cream, compounded at a pharmacy. I had to laugh when I saw the comment about putting the pill inside you. I get the feeling your doctor does not use compounded medications.?

You might call your local compounding pharmacist and ask for a recommendation of hormone doctors that use compounded estriol etc and hormone tests, especially saliva or dutch. Now that you are on a patch the serum test may not test your estrogen accurately; the saliva test or the dutch test is aimed at testing where the hormones are actually used or may show how the body is processing the hormones.
The Saliva test will check at the cellular level to see what hormones are available for your body to use, and the DUTCH test measures metabolized hormones (both free and used/broken-down) in the urine over a 24-hour period, offering a deeper look into how the body is processing hormones rather than just the circulating levels.

Hormone tests have been less than accurate over the years, but all hormone testing is in a state of flux now. We really need some current and accurate research to help us all with our hormone testing decisions.
Here is an overview of the 3 ways of hormone testing and what the strengths are for each one.

Personally, I have used the serum and saliva; for awhile I did both at about the same time, because I had 2 doctors who preferred different tests.
In my experience, any change to my topical/vaginal BHRT showed up quickly in the saliva test; in the serum test it would need to be repeated at a later date to show any change.
I think this is because the saliva showed what was at the cellular level and the serum showed all the hormones whether being used or ushered out of the body and it took some time for this "ushering" number to rise. But I don't know for sure. I would love some good research.
