disappearing line?

Caitlyn • Seven angel babies 👼 Two Miracles and #3 on the way! 💙💙💛
So yesterday I tested and I thought I saw something but wasn't sure if I just had line eyes and decided to get a second opinion on here and luckily everyone else saw it too! But said it certainly was faint and to test again today so I tested and I don't see the line today.. could anyone tweak and look for me?
