Could this faint line be an evaporation line on my test?

[Alc24]

I did a test yesterday evening and it showed negative, I’ve checked it this morning again and it shows this line. Are you able to advise if you think this an evaporation line as I am unsure?

its impossible to say as it’s out of the testing window so can’t be taken as reliable. I’d say retest and only check the result in the time frame

Yes as it’s thin

Could be! Same happened to me with my eldest.

Negative CB pit in bin and checked it that night with similar line to you.

Went to get another and was positive
