Evap or positive line?

Sarah
Hello ladies I am very confused. I am 6 days late on my period. Today I experienced very very light spotting. I only ever saw it when I wiped. (Sorry tmi) today I decided to test and I only saw one line, than 5 minutes later I see another line. It has a slight very slight pink to it. I cannot tell if this is a BFP or Evap line? What does it look like to you? I used first responce. The last time I was 6 days late I was pregnant!
