Target brand pregnancy test

Has anyone ever tried the target up&up brand pregnancy tests? Ever experienced a false positive on them? I know those are rare but holding them in my hands seeing how cheap they feel, I just can't believe what I'm seeing. As soon as the dye started to run across I thought I saw something, but gave it a couple minutes and it was still there! I ran to rite aid right after for a digital and it came back not pregnant. Can you guys see this too or am I crazy?
