Has anyone had lines get lighter and still have a healthy sticky bean?

I’m between 4-6 weeks (I have irregular periods so don’t know for sure). Took a first response and a cheap Walmart test both having decently visible lines with mid day urine and the lines were still kind of faint. 3 days later I took a Walmart cheaper with FMU but the line is fainter than before.

I’m so paranoid as is I was trying to reassure myself but it backfired.

Someone reassure me the baby could still be a healthy sticky little bean?
