BFN anxiety

Katrina • Pregnant! Due Sept. 12th
Hello! I am 5 days before AF is due and I had been buying crazy expensive tests just waiting for today. And of course... nothing. I was so sure. Having tons of symptoms. Crazy mood swings. The test said it could detect up to 6 days before. I'm 5 days before with a BFN. Does this mean I'm def not?
