When to blood test for progesterone?

Sarah • 32 years old; married
I got a positive OPK last Monday night and Tuesday am. My obgyn said to come in for blood test to check progesterone once I ovulated. I went in Wednesday morning and the blood results came back low at 1.8 - she said I didn't ovulate. Did I just go in too early for blood work? I have long cycles (35-40 days) and went in on CD28. I got positive OPK on CD27. Thanks for any help!

They told me I have to wait 7-10 days after I ovulate to do the blood test

that way he knows if the 100 mg doesnt work the first cycle he will up the dosage the second cycle

21 days after day 1 of your cycle. The easier was of saying that would have been day 21. I just had that convo with my dr today.
