Still part of natural mc or first cycle

Can natural mc only last 2 days? I had spotting all thru out 7 weeks pregnant here and there, doctor said it was normal at the time but because of no baby at u/s on aug 6. Hcg leves were 57.5 on aug 7 and 55 on aug 9th. The 8th and 9th I began heavy bleeding and passing clots but were not painful at all but minor almost not noticable cramps. And i already went from heavy bleeding to barely sprotting today, the 10th, and now nothing at all. Could this still be my body getting rid of what was there or my new cycle already thats over?
