Faint line or evap?

Okay so my last period started on March 21 and ended March 25. Well then I restarted March 31 to April 4. According to glow my period should have started 11 or 12 days ago. So last night I leave work because I’m not feeling good and my friend I work with told me to get a pregnancy test just in case. So I get home at like 4:15 in the morning and take the test. I waited 5 mins after I took it to look at it and it was negative. Didn’t look at it again. Got in my bed and went to sleep. I went in the bathroom earlier and I seen this. I’m sure it’s an evap line I just want some opinions.
