when is o day with positive OPK

mo
can someone help guide me?
I got a positive OPK on June 3 (CD15 for me) Glow is counting June 3 as the day I ovulated making today (June 12 and CD 24) 9 dpo. I was under the impression you ovulate 12-35 hours after a positive OPK which would make today 8dpo for me? Am I understanding that correctly?
