Belighted ovum...

Elena

Hello, I was wondering if anyone who has ever experienced a belighted ovum could help me out. I experienced a belighted ovum/ miscarried the day after Christmas at about 9 weeks along. My questions are how long did it take till you stopped bleeding/ having mild cramps? How long did it take for your HCG levels to go back to zero? And Is it possible to ovulate and conceive before your first period after the miscarriage? Thank you.
