Pregnancy after miscarriage

Is it possible to become pregnant 3 weeks after a miscarriage, before my missed period? I had a miscarriage on August 5th. I was between 9-10 weeks pregnant and my body has been cleaning it self out since then. I have my last appointment tomorrow to go over my blood test results from last Thursday to determine if a D&C is necessary, but according to my Dr not likely. Well Hubby and I had sex this past Sunday and today based on my cervical mucus I believe I am ovulating. Is that even possible? Can I ovulate before my missed period after a miscarriage?
