Progesterone?

I’m going to lose my mind. I called my doctor the day after I got a positive test to check progesterone and see if I needed suppositories. She called back with my results and said “you are pregnant and your progesterone is actually pretty high” I said “can I ask what it is?” And she told me “8, the normal range is point something to something (I stopped listening at that point). I want to trust my doctor but I cannot find anything online to back that statement up. I thought this was considered low? How can it be high? I’m so stressed and worried.
