Positive Line or Evaporation Line?

Mga 2 weeks na po akong delayed sa mens ko and decided to take PT para maka sigurado. First PT result was negative sa time frame na dapat syang tingnan (3-10 mins.) Then, pag check ko the next day may line nag appear. So, I decided to take another 2 PTs and same din nangyari pero sa 2 PT mas less or faint na yung line. Is this negative po ba or positive? Thank you.
