Positive or evaporation line?

Victoria

So I took this

test yesterday around 3 or 4 o’clock, and it was negative. Today at 3 o’clock, it showed this faint line. I’m desperately trying to get pregnant and am not sure if this is a delayed positive, which I’ve heard of and witnessed before, or an evaporation line, I know clear blue isn’t the best brand but in the past it proved very accurate. In my opinion it’s blue, not gray, which leads me to believe I’m pregnant, but knowing the ten minute window of opportunity I know it could be incorrect. Any input is appreciated!
