Should my lines be getting darker?

I don’t know why the first response test looks grey. It’s definitely pink in person.

Butttttt, i posted here yesterday at 13DPO. This is 14DPO with my fist pee. Should i worry because my lines aren’t getting darker. This happened to me last year when I had a chemical pregnancy 😔 i would test every day and the lines just didn’t improve. Praying this is the real deal!
