BFP or Indent?

I used contrast and warmth to see if there was any colour but it looks like an indent to me? I also posted the original photo for comparisons. My fiancé and I have been trying for 2 years now for our Rainbow Baby, with no luck in the baby making 😣

Last time I got pregnant I had what I thought was a period but I guess it was implantation bleeding... now this month the same thing happened and I’m also really tired and have no energy and my boobs are moderately sore.
