Am I pregnant? Please help!! Faint line? Or Evap line?

I’m so worried, I can’t tell if this is a faint line or an evap line.

I took a pregnancy test around 6pm yesterday (The clear blue - 6 days sooner test). I waited 5 minutes to check my test (as it said on the package) and I could swear there was only 1 very red line.

Here are several pictures of the test right after the 5 minutes wait:

However, I couldn’t throw the test at home so I kept it in a pocket and went out. 3 hours later, almost at 9pm I checked the test again before throwing it out, to my surprise it had a very fainting second line. Does anybody see it? (I’ll post the picture below this)

The reason why I took a pregnancy test is cause my period is 15 days late (Although I have a very irregular period, and took a plan B a few weeks before the time my period was due) But in top of that I’ve been having discharge with a light pink color that looks like a very light blood, and a side of cramping, and I’ve never had that before getting my period. This would also be my first period after losing my virginity and becoming sexually active.
