Progression? Tests too light for 14dpo?

Hello all! I would appreciate some advice. I have been getting faint positives since 9 DPO. At first they got darker quickly from 9 to 11 DPO, but then I feel like they have looked the same since. I had a chemical in August so I'm just really nervous that the lines don't seem to be getting darker, even though I got a positive FR digital yesterday (which I couldn't get on a CB last time). Are these too light for 10 to 14 DPO? 10 DPO is the bottom and today's 14dpo is the top.
I would really appreciate your thoughts! AF is due today and that is the day I lost the last pregnancy two months ago so just anxious today! Thanks so much! 🙏🏼
