“I see it on ____”

ABS19

So I’m guilty of this, if a pregnancy test was positive, wouldn’t you be able to tell it on all of them? I’m really guilty of saying, “I see it on the first one”’or “I see it on the second and third”. Cause I’m over here with mine saying, “I see it on the third”. If it were a true positive, I feel like it should be somewhat noticeable on all?
