Ovulate late??? Anybody??

Had anybody had glow tell you that you were gonna have your fertile days at a certain time period and the. Just kept getting those negative ovulation tests. I am so upset. I have been getting them for 4 days. So now glad has like given me a "grace day" and added an extra day onto it by moving down the fertile week by 1 day. Which is nice but what do I do if I don't ovulate anytime this week? Am I out?
