Hi, I was interested in your post at the bottom of the page. Your story sounds a lot like my daughter. She also has signs of low estrogen like very light periods; however, she has never complained of hot flashes, in fact she is usually cold. But she also tested in the carrier range. We are still trying to figure out her medical problems. Right now she is on 2 mgs of prednisone, which dropped her testosterone level very well, but she continues to feel poorly, especially with fatigue. I'd be interested to hear more of your story to compare notes. Thanks!
