Doctor checking progesterone a week before ovulation 🤔

So I’ve already had my progesterone checked privately last cycle and it confirmed ovulation. But I went to my doctor today because I wanted my hormones checked to see if I had a hormone imbalance and my thyroid checked because I’ve been struggling ttc. He said my thyroid already came back normal 2 months ago but said he’d do the blood test anyway.. he also said progesterone is the main one hes going to check. I did say will this check if my hormones are imbalanced and he said yes, But he never mentioned any other hormones he was checking. I’m not due to ovulate for another week so my progesterone is going to come back low anyway, and he didn’t even ask me where I am in my cycle. I’ve already had confirmation for ovulation, I wanted to see if I have a hormone imbalance not to see if I’ve ovulated which I haven’t yet anyway. How can he see from checking my progesterone a week before ovulation if I have a hormone imbalance? 🤨 Is progesterone meant to be a certain level even before ovulation?
