When I did it I could swear I see the faintest of line but the original doesn’t show it...the only way I can see anything was when I messed with the brightness and contrast to show a faint red line.....I shouldn’t have caved and tested at night after weeing all day 😂 help!!

Original

Messed with the contrast and can see the faintest line....

So messed with something else and swear I can see something....
