Need help - positive or evap line?

Ines

I need your help trying to figure out if this is an evap line or a positive. I forgot the test because I took two and the first one came on negative in the first 3/4 minutes and so did this one. Then I threw them out and came back later to obviously check again. And there was a clear line - it has color, it’s not really that faint.

Has anyone experienced this?
