Question about ovulating on Femara


On my first cycle with Femara, I got positive opks 2 days in a row on CD 18 and 19. Today is CD 22, I had a blood test yesterday to see if I ovulated. She said my progesterone was a little low so I may or may not have ovulated. I'm nervous now, but would I have still got positive opks if I did not ovulate?
