HCG levels after miscarriage

I was 6 weeks...These are my HCG levels right when my miscarriage started (which lasted about 4 days) to last week, because I’ve been going weekly to make sure it goes down. I took a pregnancy test and it looked positive but I’m going to retest in the morning.. So I don’t know :/

770- 7/22

629- 7/29

274-8/9

24-8/16

Still waiting for this weeks results. I kind of feel like my HCG should have been 0 by now
