Am I pregnant or left over HCG

Molly

I had a D&c on August 14 on September 21 I tested and had a positive next day started bleeding on the 22 I went to emergency room and they said it was just left over HCG that day it was only at a 5 and tested my HCG on 9/25 it went down to a 2 they said the bleeding was back to my period so after I started bleeding we started tracking again and I tested today I’m not supposed to til Monday but I decided what the heck and got a faint positive could I be pregnant or is it STILL left over HCG ! Please help
