Evaporated line or faint line?

I took a test yesterday and I was half asleep. I’m 2 days late, so I take the test and didn’t see a line. I threw it away. An hour or two later it hit me that maybe there was a line. So I look again and there’s this faint blue line. Like you could miss it if you didn’t stare at it. But I’m not sure if that was an actual line or evaporation line. I did some research on the difference between those lines. And one article said that once a test comes into contact with the pregnancy hormone it’ll turn the line blue even if it’s faint. An evaporation line doesn’t change in color. So could I be pregnant?
