I'm sorry about your loss. With my last miscarriage, I ovulated 16 days after the first day of m/c bleeding. Then after I ovulated, I got my period about 2 weeks later.
I had a miscarriage on November 20, 2011 and I just had my first period on February 9, 2012. My first period post mc was painful but didn't last that long. Good luck with yours!
