Thanks for posting your query at DoctorSpring.com
With positive B HCG levels and adnexal lesions in the ovaries, there is a strong possibility of ectopic pregnancy also.
Only serial B HCG levels would show if this is the case.
None of the scans have however raised this suspicion so far, and the heavy bleeding with clots is in favour of a miscarriage.
Also, there is no history of any fainting or acute pain.
Please have repeat B HCG levels after 4 days and a repeat scan after a week, that will clarify the diagnosis.
The cyst can only be evaluated after the pregnancy scenario is cleared.
These could be corpus luteal cysts ( normal ) or physiological pregnancy related cysts.
Blood work to evaluate a malignant component too is best done once B HCG levels normalize.
Chances of this being a malignant lesion are remote, given your age and clinical symptoms.
All the best
