first response 6 days sooner

How accurate is the first response 6 days sooner test ? Anyone get a positive 6 days before their AF with it? Or anyone got a negative but tested when their AF was due and got a positive ?? I'm taking it in 2 days and I just wanna be prepared if I get a negative with it that there's still hope if I test a few days after . Please and thank you :)
