Does anyone have any experience with FRER indents? I’ve used FRER before with my previous pregnancies, never really had many issues.

We’re TTC right now, and I’ve used multiple tests in the last several days that are ALL giving me these faint lines.

I’m inclined to be convinced they must be indents because I’ve been testing daily (sometimes twice a day even though there’s no point to that, because I can’t help myself) and the faint second line is BARELY getting any darker at all...like over 6 days.

TL;DR: Please: can indent lines appear like this? Did I get a bad batch of 3 boxes? I’m not trying to post a visibly positive test here to brag - I’m sure I can’t be pregnant if the line isn’t progressing day after day. Just very, very confused.

(Tests taken exactly following instructions. Picture taken at 3 minutes.)

Also, I am pretty sure I am 13 DPO (tracked using only OPKs and CM monitoring). Had some encouraging light spotting at 7 dpo, but then ambiguous HPTs that don’t really progress ever since.
