How many days after af till positive test?

How many days after AF was due did you get a positive test? I am anywhere from 4-9 days late according to multiple apps (I was curious which one was the most accurate.) I have taken 2 tests 5 days before AF and another 1 day after AF due (If I remember correctly) and both were negative. I am trying to not get my hopes up. I have only one symptom of AF coming, tender breast but I normally have more first. Any suggestions would be greatly appreciated! TIA!
