late ovulation

hello all! i have a question if any one could help? i have attached a screenshot of my last fertile section and then you can see a date i have circled...my partner and i happened to have unprotected sex on that day..i also took an ovulation test as i felt like i had pains and the test showed i was ovulating. im now on day four of what should be af but it hasnt showed. i feel like i can see a faint line on the pregnancy tests but it wont show in photos. when would be a good time to test?
