ovulation dip today?

I know that it can’t be “confirmed” until 3 days past, but does this look like a dip right before O? I got a positive ovulation test CD 15, peak result yesterday on CD 16, and no more peak today CD 17 but still positive. if this was an ovulation dip, would I count ovulation day as today?
