Pregnancy?

angel

I’ve been trying for a year now to get pregnant, I was on the depo birth control shot for 3 years got off of it got pregnant & got back on it for another year. Now it’s been a year that we’ve been trying I took multiple test on different days each one has a super faint line, I had to take them off of the plastic to see the strip to see it. I have about 6 more days till I start my period could this be positives or Evap lines ?
