I had that same problem. My doctor did hormone levels and we found that it wasn't the usual estrogen/progresterone levels so much as other hormone levels that were down (vitamin D, DHEA which is a precursor to estrogen etc.) So maybe ask him to expand his list of tests to include as many hormones as possible. I am now on hormones and cannot even express how much better I feel and look not to mention that everyone around me is happier now too :)
