Please help - is this a chemical starting to show?

I got pregnant first cycle after my miscarriage. However, I don’t feel like the lines are progressing. The Boots tests seem to dry exactly the same regardless so it’s hard to say with those but I thought I’d see more of a difference on the FRER. I’ve also attached a couple of pictures of the 14DPO FRER when it was within the timeframe.

Is this a bad sign? Please be honest.
