Positive or not

Hello yesterday (Friday) I tested with rapid first response 1 min result and got a faint line I was 8dpo, Saturday 25th at 9dpo I used clear blue and got a faint line so I thought it was safe to use the clear blue digital but it said not pregnant, is it still to early do these tests look promising? I believe I am but I want to see darker lines and get a digital to say pregnant.
