HELP!!! Progesterone check too early??

Shae

So I have a normal 39 day cycle but this cycle I took Clomid. I ovulated on Cycle day 18 and my doctor checked my progesterone on CD 21. It came back at 7.95. They said I didn’t ovulate because it wasn’t 12. I think they checked it way too early. What do you think? What is normal for 3PO to confirm ovulation? Has this happened to anyone before?
