Faint positive 5 weeks after miscarriage?

Liv

Is it possible this is a new pregnancy or old hcg?? I was 11 weeks when I miscarried and ended up with a d&c. It’s been 5 weeks since my MC so I assumed all hcg was out of my body. I haven’t had a period so I just thought to take a test since so many women get pregnant immediately after MC. A faint line immediately popped up. I did not have blood work done for my levels. Don’t want to get my hopes up but confused of what’s going on!
