Pos opk but low progesterone? Confused!! Help?

So I’m on cd 14 I got a positive opk today at 11 AM but had my progesterone drawn today at 9 AM and it came back a 0.494 can I still be ovulating in the next 12-36hrs ?? I heard progesterone takes a week to rise after ovulation but Is a 0.4 to low to be ovulating in the next 12-24 hrs ?
