Currently-married women in a Sundanese agricultural village were measured for the prevalence of pregnancy, the duration of postpartum amenorrhea, and the waiting time to conception. To identify pregnant women, an immunologic pregnancy test was used and found to be more effective than interviews. Tests for 361 reproductive women revealed that over 40% of currently married women, 15-19 years old, were pregnant both in rainy and dry seasons. The percent declined in older women. The high proportion reflected the short (inter-) pregnancy interval. A eighteen- month interval of this age group consisted of 10 months of postpartum amenorrhea and 8 months of waiting time to conception. The (inter-) pregnancy interval became longer by the age of 25-29 years because of the duration of postpartum amenorrhea rather than the waiting time to conception.
