Are my lines getting lighter

Breeya

I am supposed to 4 weeks today according to flow and glow, and im just worried cause I have had a miscarriage earlier this summer. The top one is from last night and the bottom is earlier this morning. And it just seems like the line is a little nothing. I know it’s probably nothing but the bottom on looks a little lighter, I think I just need some reassurance. Im so afraid of another miscarriage.
