Trying to figure out when I ovulated

Kaitlyn
Progesterone day 21 is 4.9, estimated mid luteal phase 5.19. How do you you figure out when you ovulate. Is it day 14? I know progesterone should be over 10 but my dr. Said ovulation is anything over 3. Repeat bloodwork in 2 days. If anyone can help explain I would appreciate it!!
