Da Rosa, parts of your story sound similar to mine, minus the PCOS. I stopped ovulating for several months and so I got FSH and LH tests done to find them normal. Then I ended up getting saliva tests done (which are more accurate at testing the free hormones, not bound hormones) and my estrogen levels were sky high.
My TSH was initially 2.05 with low normal FT3 and FT4 like you as well. My doc went with thyroid replacement and now I belive that after 8 years of struggling with my health that I'm finally onto something. Don't give up. Nat's right (as usual). Find another Doc who will treat you. Here's a link to help you:

Nat, I'm no expert on DHEA, but I can relay my experience. I'm not sure how I feel about DHEA-S blood tests. Mine showed my blood test levels equivalent to a 70-79 year old.
It didn't use a specific lab range based by age for some reason. But my saliva tests (testing the free hormone, not bound hormone) showed normal levels.
I think the reference ranges for DHEA-S are skewed, just like so many of the other lab tests so it's hard to sort out what's normal and what isn't. I've also heard that DHEA should be tested by age group, not lumping everyone together since DHEA declines with age. Women also need less of it.
BUT, if DHEA is low, it's a fairly good indicator of adrenal fatigue. I just don't know how the results are interpreted on a blood test that doesn't really have adequate reference ranges. I'd be more inclined to get a 4 point cortisol saliva test to determine adrenal function.
