evap? I'm so confused on how dark it is

sorry they look so grody I took both out of trash 😣 but the one with the 2 lines was 2 days ago. and the one with 1 line was yesterday. I threw both out at 5 minutes or 3 and nothing was there by those times. Then yesterday I say the 2 lines and I decided to test again and nothing. not even this morning... so I'm confused. I start my period in 2-4 days
