Feel like I'm going crazy and seeing things!!

Need some other sets of eyes on this please. Noticed a vvvvvfl that I can see, it's a bit clearer in person, but I took a picture and you can't see it quite as clear so I grey scaled the picture using a pregnancy test checker app and I think I see it. Is it just me and I have line eyes? 😩 and when should I test again? Thank you x
