I don’t know what’s wrong?

Hello.

My period is three days late. The app is accurate for my period. I already have a one year old. I took a test yesterday and it clearly is a negative.

But I took another one when I first woke up.

It looks negative but at an angle , I think I see a very very very faint line or my eyes are playing tricks with me. Can you help me out if I’m seeing things? If I’m not pregnant, idk what’s going on.
