Faint blue line on pregnancy test after close to an hour?

Here's the deal. I took two tests, one produced a faint blue line after an hour and the other one did nothing after like 3 hours. I read that evaporation lines are supposed to be gray and only seen in light. Yes, I know you shouldn't read them after 10 min, but because the other one looked nothing like it after an hour IDK what to think. Last month I had spotting like 4 days after sex and then a somewhat light and drawn out period somewhat earlier than my normal time. I've also been super fatigued (near fainting one day), my temperature has been high for almost 2 weeks (yes, I did think flu first, but I never got sick). My breasts are also sore and my nipples are darker. I also took the test at night, Idk if that would make a difference though if it's been 6 weeks. Honestly, I don't want to be pregnant so it's not wishful thinking, I just don't know what to think at this point.
