Smudge past time limit

I know that pregnancy tests are not accurate or should be dismissed after the time limit, BUT on every test I have taken even after the fact I have never seen a ‘smudge’ mark like this show up. Just curious what others think it is related to. The test is obviously negative, and I am way early to be testing (can’t help it) but this is the first time I have come back and notice anything like this. It has a yellow type of color along with a slight pink coloring in it as well... is there any chance it could be maybe the the start but the hcg levels are just not strong enough yet or am I sounding like a crazy person that’s need to sit down and attempt to be a rational person in the TWW?

Dollar store pregnancy test - 6 days before AF- 8 dpo - taken with fmu.

Thanks for any input- I have a feeling I know the consensus, but just want opinions. (And yes, I will wait and try again in a few days as well)
