Positive or Negative? Tweak please

Can anyone tweak this for me? Does this look like an indent? Took these about a week ago, so i haven't retested yet. I feel like I can see a super duper faint line, but I don't know if it might just be my eyes playing tricks on me or if I actually am seeing a super faint line. Both tests were taken at the same time and the photo was taken within the timeframe.
