BFP but worried about line progression?

I had a chemical last month after getting so excited, and I’m worried the same will happen this month!

Here’s my side-by-side of 9DPO (FMU) and today/10DPO (SMU). Does this look normal for a little less than 24 hrs?

Thoughts? I haven’t taken a digital yet, but I feel like it should be a bit darker before I do?
