Took one hit of a joint 2 weeks ago. Drug test shows the lightest gray line on negative. You almost have to squint to see it but it's definitely visible. Is this a negative by some miraculous chance?

I'd post a picture but I don't know how sorry.

Edit/update:

Just took the test today (attempted to use wife's p). I walked in the urgent care and they told me it was a 2 hr wait so I went to the bathroom assuming it was going to be a while and took a leak. The second I walk out the nurse is outside the door and asks me if I had pissed. I told her yeah and that I expected to be here a while and she handed me a water and told me to get her when I had to go. 30 min later I wait for when I actually have to p again and go back to p. I piss and at the same time stab the condom and let it drain into the cup, there was no sound and I heard the nurse on the computer outside. The urine level was above the line she told me to fill it too and she claimed it wasn't enough and poured it out. So I tell her I need more water and she refuses to give me any and tell me that if I leave I'll fail. So I wait about 40 min and go back to piss and they make a male nurse watch. I'm extremely stressed about failing and I'm not sure what exactly made them so suspicious but I'll let you know when I get the results.

2nd Update:

Around 25 hrs after the test I got flooded with paperwork from the company and they had me do online training. Was told I start Thursday so it looks like I passed.
