Did I ovulate?

Ze

Hi!! I’m 26years old with pcos. So I have irregular periods all the time. Last month doctor gave me medroxyprogesteron (similar to provera) to start my period. I had 6 day period and I started to use opks on day 10. The question is did I ovulated before day 10 or on day 19 or didn’t I ovulated at all?? What do you think??
