What’s your thoughts?

Hi all! So I’m 10dpo..I think! And done these tests with fmu. The first picture and the test with the smaller window frame is a Asda pregnancy test where a faint line appeared straight away. The bigger one frame (the one on top in the second photo) is a one step test and nothing on it😢 I’m worried this is a false positive since there isn’t anything on the other one. What’s your thoughts?
