How many days past ovulation am I? HELP!!!


okay so I had my period on November 12th till the 15th. glow predicted that I was to ovulate on the 22nd. however I believe that I ovulated either on the 19th or 20th due to having a ton of ewcm since the 18th till the 20th (at night). if I ovulated either of those says how many days past ovulation would I be? Also how do you calculate dpo? please help.
