Faint line or invalid? (Result on edge)

So I am neurotic and I test every day after ovulation. I am only 6DPO so I KNOW, regardless, I have to retest...but I got a pink faint line but on the edge of my test. I've never had this happen before. Is this invalid? Is this a future positive?

****The photo wouldn't focus on just the edge of the test so it's not a great pic. I promise it was MUCH brighter in person.****
