Equate test brand

I hate to use it but Walmart was out of the cheapies as usual. The grey line was already there before I took the test and had chips of no color like I'm my picture. Is it still valid?
Obviously probably still negative. I'm 11 dpo and glow told me to test. Feeing like I'm out for sure this month 😭
