A little worried

So. I had a positive test at 10dpo. The tests got darker until yesterday (13dpo). Today's (14dpo) looks lighter than yesterday. Don't these lines look super light?? I did get a positive on a digital but now I'm worried. I also attached the test progression from my last baby - look at how DARK those lines were! I got those positives at 8dpo. Why are they so faint this time??
