Lines not getting darker?

Lindsey

I missed my period on Tuesday… it’s now Saturday night. I had a faint positive initially and it got a little darker the first couple of days. But the last 3-4 days it hasn’t gotten any darker. It isn’t getting any lighter either but I’m terrified as I just had a miscarriage at 12 weeks in June. Should I be worried? This is the latest test at 6ish minutes but this is as dark as the line is getting.
