Pink line hidden inside FRER...??? Help please!!

I might be the world's most desperate woman for a bfp, but I just took another test and saw something strange... I couldn't tell if what I was seeing was line or indent, so I took the test apart to hold the test strip up to the light. When I did, I found a light, but still very noticeable pink line hidden inside the test. This line did not show up in the result window (as it's about a centimeter too much off to the left), but I have taken tests apart in the past many times, and have never seen this before. Am wondering if this has ever happened to anyone else, and if so, what does it mean? I'm about 8dpo and hoping maybe this is the very beginnings of what will eventually turn into a bfp... I have no clue though. Any insight would be so greatly appreciated! Thanks ladies!
