evap line or pregnant?

So I know this looks pretty obvious BUT this picture has 2 darkening filters on it and that's the only way you can see that super faint line. The original picture to the naked eye looks like a negative result. Has this happened to anyone else? Is it just an evap line? I'm still 7 days from missed period so I'm wondering if that's why it's super faint? Or if it's just the underlying line from the test itself and I'm just crazy?
