Is it possible to have leftover hcg from loss 2 days after first pp period? Or am I pregnant again?

When I first delivered at 20 weeks 3 days I bled for a little over a week. My bf and I have been intimate since. I know we should've waited till 6 weeks but things happen. Anyways at a lil over 5 weeks postpartum I got my 1st period although it was shorter than usual but still had a day of heavy flow... Well I felt off so decided to take a test 2 days after ending period and both are positive. Is it possible to have left over hcg after period from loss? Or am I early pregnant
