I had my progesterone levels drawn last week on CD 21. They came back at 86

That was only 6 dpo (and I know exactly when I ovulated because I was being monitored daily by my doctor), and I'm not on any meds. At that point I think they should be around 10-15. He says that they could be high if I am pregnant now. But even if I am pg, that seems like a really high number for that early. Does anyone know anything about this? You'd really help put my mind at ease! I'm scheduled for a beta test on Thursday, but I just don't feel like this is my month. The whole progesterone thing just really throws me off.
