Evap line ?

[Sdrek]

Hello I am wondering if anyone if familiar with clear blue evap lines? Ive read and heard that evaps are usually grey or no color! I took a test with my first pee this morning , I wait two min the test was neg , I put the test away and left . I went back to show my sister the test ! because she loves to look for lines 😂 . when I looked at the test I saw a blue line! I took another test after seeing the line and it was neg. it also did not form a evap line .

any other people experience this ?

Def evap line. It's thin (if positive it would be the same width as the control line). It's frustrating but on these tests evaps have colour.

Thank youu for the reply ! I was def confused by the color ! Lol I probably wont use these again !
