How long did you wait to start charting your BBT after miscarriage? I just had a miscarriage about a week ago and I'm not sure if I should wait until my period comes to start charting again or if I should start charting as soon as my hcg is back to 0. Thoughts? I've also heard various answers about how long you should wait to conceive after miscarriage. We are both dying to start trying again, but I don't want to conceive too soon and risk having another m/c.
