Notes
The calculated months of postpartum amenorrhea give the duration of amenorrhea as in M6, but with the duration calculated if the period did not return after the birth and before the following birth or the date of interview. Inconsistent durations based on the original reporting of the duration of amenorrhea are recoded to 97. In cases where the duration was one month longer than the interval the duration was shortened by one month, consistent with the "Rule of one" applied in DHS I.
