Pregnancy test - faint line and then negative 😢

So I posted on here the other day, about my test I did on Thursday and asked if anyone could see a faint line.

I then did a clear blue digital test the day after (Friday) and my result was ‘not pregnant’ .. 😢

Did another test this morning (Sunday) and I’m sure I can see a faint line ...

Advice please?!

Which test is more accurate? The clear blue digital?

Picture 1 is the first test on Thursday

Picture 2 is the third test I did this morning.

Can anyone else see a line??

Thank you ladies ☺️
