Evap line?

Took these last month 2 days before AF was due, the line showed up within the time frame but started bleeding halfway through the day when AF was due, not heavy or anything period like but I figured it was an evap line since it wasn't directly in the middle and these tests are known for false positives. (I apologize for my dirty counter hubby just shaved his face and clearly didn't clean up his mess🙄)
