Evaporation line of faint positive?

Okay, I feel like I’m crazy at this point because I’m definitely an obsessive tester. I took this test because I had some very light spotting the last two days (but I also noticed the spotting after sex.)

My period is irregular and I just came off BC in April. I had one long and heavy AF in June, but nothing since. Ive been trying to track my cycle, but it’s been a struggle, so I kind of gave up to just see what would happen.

All that to say, could I be pregnant or is this an evap line (I mistakenly bought the blue dye 🤦🏽‍♀️). It showed up maybe 5-8 mins or so after I took the test I think-I walked away.
