Evap or Positive?

hey ladies! so I took this test around midnight the other night and after 3 mins, I concluded it was negative. I know I know... I shouldn't look after time allotted but I happened to look at it about 10 maybe 12 mins at the latest and saw this.. now, I've never in my life seen an "evap" like this. my Evaps have always had either no color or slight color but a very very thin line. this is bold and thick. I'm so confused! can y'all help me? I'll be taking another one in a few days but until then... any help with this one?
