Vvvvfl? Or indent?

The top one in each pic isn't the test I'm wondering about. That one is a pic from my first pregnancy at 11DPO, I used it to show where the line is with the FRER I just took (Only 8DPO..will retest in a couple days). I swear when I tilt it just right I see something. In person it's pink though super super light, so idk if it's an indent or what? I took the pic three mins after taking the test, the colours are slightly odd because I was tweaking the brightness and vibrancy slightly
