Advice!?

So AF was supposed to show up on the 25th of December. In my TWW I took about 6 PG tests including one on the 24th. All of them were BFN. I haven't taken one since. Now I am a week late. I don't want to test agian just because I have had no symptoms and multiple negative tests. Has anyone tested the day before their missed period and gotten a positive a week later with no symptoms at all?
