Because pregnancy usually begins two weeks after a woman's menstrual period, and that is the time from which the beginning of pregnancy is measured. c. Because the duration of pregnancy actually gets longer as a woman ages, and it ranges from 38 to 42 weeks. 40 weeks is the average, so that is what people say. d.
