The duration of postpartum amenorrhea after the birth of the child in months. The maximum period allowed during the data editing was the interval between the date of birth of the child and the date of conception of the following child (date birth less seven months was used for the date of conception) or the date of interview if there was no following birth. Cases which exceeded this duration were left with the original response, but are coded with one of the flag codes on variable M28 and were set to code 97 "Inconsistent" on variable M7.
