Still bleeding 5.5 weeks after MMC

Hi everyone, seeking your advice today. I had a medical miscarriage on 11/5. I took mife on 11/3, miso on 11/5 and 11/10 and my HCG has just gotten to 8. I have been bleeding since 11/5 with a few days of no bleeding sprinkled in. I had some bad cramps the last few days so I thought my period might be coming but my flow is so light compared with my normal period. I passed a massive clot last week (orange sized) and went in for a pelvic ultrasound but my doctor thinks that since my HCG numbers are going down it’s likely not RPOC.

Has anyone dealt with RPOC or prolonged bleeding with low HCG? Any advice here? I was trying to avoid a D&C but now i just want this bleeding to be done, I’m just so depleted.
