Can evap lines be there and thick?

C

I think this is an evap line because it came well after the time allotted, like more than an hour, but I have never ever had an evap line before, and I thought they were supposed to be thinner and lighter? If you could shed some light, that would be wonderful. I don’t know what DPO I am, since my daughter is 6 months and I haven’t had a period yet. I took the test because I have felt some cramping and nausea.
