when did I ovulate?

Hi guys! Been TTC since my miscarriage in May. Was put on Metformin this month for my PCOS. (1000mg dose) I got a peak test on CD 22 and CD 23. Usually I dip the day I get a positive O. This time I didn't dip until CD 24. On CD 24 you can see my temp had a dip, then keeps rising. Not sure that I should count that as the actual day of ovulation to count DPO. What do you guys think!? Do you think my egg released on CD 24? Here is my chart too.
