Are these pregnancy tests positive? What’s going on???!!

Okay so I took a clear blue test yesterday and saw a faded line but it looked weird. I tested again today with a digital test and it said “not pregnant” so I took it apart to double check and I heard sometimes they are inaccurate and I see a faint line but darker than last nights. Am I pregnant? I’m 8 days late on my period.
