Faint Line

I am currently 9 days late, and I just tested. There is a faint line and it's positive, I've had multiple people confirm. I'm just nervous because we had a chemical miscarriage and faint lines scare me now... how does one get over this? Is it normal for the line to be faint after being 9 days late? I should add that this would've only have been my third period after my last miscarriage so it was still a little irregular.
