Possible for Hcg to still be present 6 weeks post D&C

Jane • 2 angel babies and praying hard for that rainbow🌈

Took a pregnancy test today as my period still wasnt showing.

We had a missed miscarriage at 8 weeks with baby having no heartbeat. Did a D&C on 12 July.

Just wondering whether it is possible for Hcg to still be present this long after a D&C?

We only had unprotected sex once 3 to 4 weeks ago
