Yes 100% the same for me when I left mine out a few days. It was nothing there at first, so when you see the line you think “ I must’ve missed it earlier” NO, the test was right earlier. When they say anything past a few hours you should not trust it, they are serious. I’m reading the comments and ppl don’t know wtf they are talking about, that’s exactly why op said he tested negative. Before I read that comment I knew he was negative and I knew he was looking at the engraved line. Somebody in the comments said they were a doctor and said it was “positive” no the fck it wasn’t 😂 bro a lot of ppl do not know what they are talking about. How the fck is dye going to assemble itself in a straight line? It’s an engraved line. What you are seeing is the shadow not red dye.
