Progesterone

I got a blood test & it was determined I had a chemical pregnancy. I was put on Clomid then day 21 I went in for blood work. Results came back that I did NOT ovulate and my progesterone was low. The Dr. said he wants my progesterone to be at a 10. I don’t know what that means or what it should be at. But they gave me 400mg of it to help start my period. I’m irregular & I don’t ovulate so I’m going to take Clomid on day 5-9. Has anyone gone through something like this?
