Hcg levels

Andrea

Okay, so I got my bfp on 12/18 went to doctor next day because I’m high risk. Hcg was at 168, did another blood test on 12/23. It was down to 94, so we went with miscarriage. It’s now January 4th and I got a faint line on a test. My hcg levels should be down to nothing by now right?! I’m so so so confused right now. I don’t know what to think.
