Faint positive 3 1/2 weeks after mc

Shannon
So basically I had miscarriage on the 14th December and 6/7 weeks pregnant, on the 17th of December my hcg levels had dropped massively to 49. Something was in my head to take a cheapie last night and there was faint line that even my partner noticed (probably a clearer positive then when I found out I was pregnant on that certain test) I'm unsure if it's even possible to be pregnant this soon? So is it just old hcg? I will retest in a few days but if anyone can share there experience it will be greatly appreciated  thanks
