In DHS we have two ways of collecting respondents children: A birth history or a pregnancy history. In surveys where we collect birth histories, it isn't possible to deduct the number of pregnancies because we only have terminations (stillbirths, abortions, miscarriages) for pregnancies in the last five years. In surveys with pregnancy histories, to determine the number of pregnancies besides the current pregnancy status, it is important to take into consideration those pregnancies that ended in multiple outcomes (twins, triples, and so on).
