Just my experience here and I’m no expert. But maybe since you know progesterone is low you could just focus on increasing her progesterone (take progest e and if needed, increase thyroid production, also have the daily carrot salad). When I was having horrible symptoms years ago I did a saliva test that showed very low estrogen and progesterone. I had been assuming I was estrogen dominant and when I got this result I dropped that theory. But now I’m thinking maybe estrogen was still a problem for me at that point …I’ve heard Ray talk about menopause and how the estrogen is accumulating in the tissues so while your blood may show “low estrogen”, the tissues still have excess estrogen. Estrogen becomes locked in the cell and the blood becomes deficient…this is my understanding of what Ray said. Taking progesterone would kick the locked estrogen out of the cells. So perhaps years ago my test results that showed low estrogen actually meant I had high estrogen locked in the tissues, and perhaps this is the same for your girlfriend? Just my current theory
