Could this pregnancy test line be an evaporation line or positive?

I took this test mid morning today. I didn’t use first morning urine & my period is due Saturday 2nd may. I have felt genuinely unwell the last few days. When I took this test I checked after 3 minutes didn’t notice anything at first I then left the test did a few things around the house & an hour or so later checked the test & to my surprise I saw this. I’m aware of evaps ect but is this not too dark?

I’d say positive.

Hard to know for you but unfortunately I have definitely had evaps that have looked like this. I’ve learnt through experience that you really have to disregard outside the time window.
