Period after Miscarriage

Dantri
How long after a miscarriage did it take for you to have your first period? I lost my first baby last month at 6 weeks. After getting the ok from my OB, we starting trying again right away. I think I ovulated a couple weeks ago (I'm not certain. I had EW CM but didn't use OPK), but I have no clue when to expect AF. Any advice would be appreciated. Thanks in advance!
