When to test for ovulation?

Bianca? • 23 years old glow and fertailaid helped me conceive my first love👶💕
I am trying to see if I even ovulate. I was told I have mild pcos and need to start temping and charting opks. I'm a bit confused as to when I should test I am currently on cd2 had a 29 day cycle and which is normal its in between 28-30 days. Any advice ladies? Oh BTW I am 21 ttc#1 not on any fertility meds as if now my gyno wants to see charting bbt and opks first I have an appt in 3weeks with him so we will see?
