Negatice test 5 days before AF

So I got a negative test 5 days before AF, the only reason I thought I may get a positive this early is because with my first I got it a week early and my second I got it 4 days before AF. Since I got them this early before could I still be pregnant or is it a true negative? I ovulated sometime between the 14-17. I used a first response early result.
