Need help with ovulation tests

Ok so I only recently decided to track ovulation with tests. I did miss a few days but I’ve been trying to keep up. I just feel confused because I feel like I should’ve ovulated already based on when I last had my period which was the 5th-9th. But every test doesn’t appear to be positive to me or the app premom. From what I read it’s positive when the test line is as dark or darker than the control line. I just feel stressed bc the longer I don’t ovulate the longer it’ll be before I get pregnant. I’m trying to relax but I can’t help but to stress.
