Indents ?!

Is it just me or has FRER tests been major wonky lately? I don’t have a period because I’m still nursing my lo , so I’m not sure how many dpo I am , but I have had 3 faint lines in a row from FRER and I just can’t help but think it’s an insane indent. It’s way more visible in person, but definitely there and the other two were definitely pink. I know I know they’re not valid once they’re broken apart but I have really bad eyesight so looking through the window is no help for me.
