I know FRER has a tendency to give indents, but I feel like there is color in the faint line. Hubby says indent, but I want to make sure I'm not seeing things. Thoughts?

These were taken in the 5 minute time range.

I have no idea how many dpo I am because I wasn't tracking. However, my period is either super late or missing. I'm just trying to get a second opinion before going to get checked out for hormonal imbalance/PCOS. Thanks!!
