Faint line or am I losing my mind? 😅

Hey y'all! So I've been having some pretty frequent symptoms these past 3-4 weeks, with nausea being a BIG one lately. To the point where I've actually been feeling like I'm going to vomit + I have to rush over to the bathroom. I took a test just now even though I'm still about 14 days out from getting a more accurate test (according to my fertility app). I thought I was seeing a line in the bathroom, so I stepped out to get natural lighting. My eyes couldn't focus + the flash on my phone wasn't making things clearer. Anyways, I decided to just put up the test against the sunlight + I'm not sure if this is a faint line that just wasn't showing up when the test was looked at with more shadowing (on a flat surface) or if it's just showing because it's part of the test?
