Pathophysiology of pregnancy

All maternal organ systems undergo physiologic changes during pregnancy; the majority of these changes go away after delivery. In comparison to single pregnancies, the alterations are generally more drastic in multifetal pregnancies.

Missing a period is the first indication of pregnancy and the main cause for most expectant people to visit a doctor. A menstruation that is more than a week late in sexually active, fertile-age women who also have regular periods is presumed to be a sign of pregnancy.
