Can a HOME PREGNANCY TEST tell if you are pregnant at 2 12 weeks?

I am not entirely sure what you are asking here but...According to the ClearBlue pregnancy test accuracy results they are: 4 days before expected period= 51% accurate

3 days before expected period= 82% accurate

2 days before expected period= 90% accurate

1 day before expected period =95% accurate

the day of expected period =99% accurate
