Super light / almost invisible line

Does everybody else get super light like invisible test line on their OPK's very early in their cycle? Is that normal? How long does it take for the lines to get darker? I know it depends on when I get my hormone surge. I'm just confused lol I can see them more in person. I'm on cycle day 14.
