10 dpo dark line??

Hi there!

So I’m 10 dpo today. Got a BFP yesterday and it’s WAY darker today. Is this normal?? I had two miscarriages over summer, and it was this dark at like 15-16 dpo for me. Just so anxious lol!

Thoughts?? The top test is yesterday afternoon, and bottom is today.

Praying this is a good sign!!
