I want to participate, but my dates are different. I did not receive a hormone test before starting HRT. My tests will represent 2, 5, 8, 11 months. I still believe that they will be usable. I should have something to add in a few weeks. Also, my doctor is following the Callen-Lorde protocols and that will give some information that you may need. I take Spironolactone and the Patch.
