Can anyone see a line?

Hey guys, I took a test this morning, Can anyone see a line on here? I couldnt at first, but when I've gone back to check the test about 5hrs later I could (I know you shouldnt but!)... so I took it apart and there was definitely a faint line on the paper. Could this be an evape line?
