Really unsure.

I took a pregnancy test and let it sit for about 10 minutes. It was a few minutes longer than the package recommends. I noticed a faint line and threw it away. I noticed it sitting in the trashcan because it looked darker. I’m not sure if it’s evaporation lines. I took a couple more tests all negative and a digital negative do you think it’s a positive or evaporation lines

Pregnancy tests are only valid if read in the timescale stated on the packet. So yours isn’t positive or negative, it’s invalid. If you used the others correctly and they’re negative then you’re not pregnant (or it’s too soon to tell).
