Unsure. Can anyone see anything?

I'm 11dpo.  Af is dur tomorrow.   I took a test yesterday-stark white bfn from the same box.  Today, I took this one and in person I can almost see a hint of a line if I really look at it.  I feel like I may see a line in this picture, but could be completely insane and yes, I did take it on my carpet.  I went into just about every room of my house.
