Miscarried/DNC at 10w. Now 6w later, can I be?

Jami

I had a DNC at 10w, baby stopped growing at 6 and found now heartbeat at 10. It’s now 6w later or a tad more. No period yet, took some stick tests and faint lines. Could I be pregnant again? Seems a bit far out for leftover levels of HCG.

We had sex Monday & Tuesday before last. Only measure I could possibly use if I am.
