Not pregnant?

I can’t tell if my first test was a fluke or i read it wrong or if FMU is making that big of a difference but something is off. First test taken yesterday with FMU has a clear faint line. Second one was taken a few hours later and has maybe a faint line. (Both are easier to see in person) Then this morning I grabbed a test and didn’t realize it was a digital 🤦🏼‍♀️ so FMU was negative on the digital. So the third picture is about an hour and a half after FMU and looking pretty negative. Obviously I’ll test with a pink dye in the am but I’m starting to think that my first test was a mistake. Thoughts?
