Positive???

My period isn't supposed to be until 10 more days but I'm pretty sure it will start sooner than that my ovulation seems to be pretty early in the month but I got impatient and tested today the bottom one was at about 2 min. The one above that 3 mins. And the top 2 about 5 and 6 idk if this is positive or evap line. How common are false positives? It also got darker but it was past 5 min.
