Progesterone Testing after LH Surge

Lissette • Married - 30 years old - TTC #1 - PCOS diagnosis.
Hi! I have Pcos and am on the journey to figure out if I'm ovulating. My doctor wants to test my progesterone 7 days after I detect an LH Surge with an ovulation test (detected on June 19th in the evening, blood work scheduled for tomorrow morning). But online I keep reading about that usually being done 9 days after the surge because that is about 7 days after ovulation. Anyone else experience this?
