Is this an indent, or do you see something?

AF due probably in the next 12ish hours. This is my first CB test, and I’ve heard they’re notoriously bad for ~misleading results due to the indent. My local store didn’t have a FRER in stock.

I think I see some blue in the line half the time, then the other half I’m sure it’s the indent. Thoughts? 🤷‍♀️
