Does that mean my test was invalid?

I took a pregmate strip test this morning with I think a 4 hour hold. I know it’s a bfn but can anyone else see the dye run or pink spot on the side? Does it mean anything or is it a faulty test? I am just asking as I’ve never seen that before when testing.

I will add that I am expecting I am at 10 days past ovulation per opk. I will re test in 2 days.
