Worried

According to glow I am in my fertile window, however I have been taking ovulation tests and checking my temp, cm, and cervix and nothing indicates that I am in high fertility. My fertile window started monday so with it being friday I am worried that I wont ovulate this month. Normally I would have gotten a positive test by now so its so weird. I am due for AF according to glow on the 4th of August but theres no way if I wont ovulate. Has anyone ovulated late before and was still able to get bfp? Idk what is going on I normally dont have this issue.
