Positives, Chemical, or Indents?

Hey ladies! So I do fertility treatments, and test out my trigger shots until they’re negative. Yesterday, I had a pretty positive test at 10DPT(8DPO) but today at 6pm, 11DPT (9DPO) the test is a bit lighter. Both have pink tinge to them in person. Just curious, would it be lighter because I’m still early, and because it wasn’t FMU like the day before? Or could it have been a chemical, or do these look like indents? Any ideas appreciated!!
