Was just wandering how many

Was just wondering how many ladies, who have 31 days cycles, who ovulate around the 12-13th, how many of you didn't get a postive pregnant test til they were a week late? I'm 5 days late and still bfn. Hoping when I test again in 3 days it will be postive if AF doesn't show. Have a feeling she isn't tho. :) thanks for any advice And baby dust.
