I'm kinda confused can someone help me

Serina • 1 👼 baby 3 year old 🌈 Baby on the way ❤️

I'm not sure what to think here, I see a faint line on the top one but I don't see anything in the other two. They were all taken with the same urine. Can someone help me out here? Am I pregnant? Tweaks welcomed

Top- first test taken

Middle- second

Bottom- last
