Clomid

I need help figuring out when my ovulation day is after taking clomid. Last period was on Dec. 25-31. Took clomid from January 7-11. Baby danced on January 16, 18, 20, 22. I need help figuring out when is the right time to take a test. I have PCOS so I’m not sure if I should follow the app for ovulation day
