Evap?

So a few days ago I took a test but didn’t see the results until later on in the day. It was 2 lines .. I was confused , I thought it might be a Evap but it was a little to dark...so I decided to test again and one line. Should I test again or leave it as an Evap line?

Top one is the one I took a few days ago and the bottom ones I took today .
