Did you get a copy and do you know when in you cycle you tested and how that matches up to the ranges?
Ever had sodium and potassium tested? AI is a salt wasting disease so those have to be off.
You need testing, find another doctor. It may or may not be cortisol though.
Def search for an endo that listens to you and your concerns. I'm not a doctor, but it sounds like it could be androgen excess- ask your doc if that is a possibility. Feeling wired, excess hair, lean body, irregular periods and excess testosterone production all seem to point to it. Get your testosterone, free testosterone, DHEA and androsteneidione tested- they vary depending on where you are on your cycle, so ask your endo when you should get them tested. Good luck, wishing you all the best <3
