I thought your progesterone was checked 7dpo 😐?

Soo I got a progesterone test and I know for sure I either ovulated on October 29th or October 30th my doctor did the test on cycle day 22 which was November 2nd for me and it was at a 16 and she said that means I ovulated which is true but the thing is mines wasn’t done on 7 dpo it was done at 3 dpo and it was at a 16 I wonder if that matters ? 🤔
