When is the maximum time to expect my period after natural miscarriage?

About 5-6 weeks: This depends upon how far along you were, but assuming that you were 8 weeks or less, it will take a couple of weeks for the HCG levels to get low enough to "unleash" a new cycle. That is why i assume about 5-6 weeks until the next normal period. If it does not arrive in 6 weeks, a repeat pregnancy test and visit with your ob/gyn is warranted!
