I had a mmc & completion mid September. My bcc levels were as follows:

October 1 -550

October 11- 220

I got a negative hpt around the following week so I figured I was at least under 25 at that point. After some irregular bleeding my doc suggested another hcg test since I never had it documented at 0 post mmc. The results came back today and my hcg levels were 10. Do you think this could possibly be a new pregnancy?? It seems like all of the hcg from first pregnancy would have passed, no?
