Would it be left over pregnancy from MC OR new pregnancy?

I miscarried in October 18th and today is November 18, I just did a pregnancy test to make sure everything is out of my system. Is this a positive or just the leftover from my previous MC weeks ago? Sigh...anyone been pregnant with new pregnancy within 4 weeks after MC? What do u guys think? It’s a faint positive? I was 8 weeks and 5 days when I miscarried.
