Faint line progression! HELP! 😭😭

Kajeen • Married with a 14 year old girl and a 4 year old baby boy! Pregnant with baby #3 👨‍👩‍👧‍👦

I’m 4 weeks 3 days according to the app. This is how my line progression looks. Anyone else have similar line progression and have a successful pregnancy? I’m worried it’s not getting darker or dark enough. My period is due in 2 days. I have 33 days cycles!
