William Hunter, Anatomia uteri humani<unk> idi tabulis illustrata,alt=Title page from an 18th-century book about<unk>  Associated terms for<unk>  are<unk> id and parous.<unk> idus and<unk> id come from the Latin word meaning "heavy" and a pregnant female is sometimes referred to as a<unk> ida.<unk> idity refers to the number of times that a female has been pregnant. Similarly, the term parity is used for the number of times that a female carries a<unk>  to a viable stage. Twins and other multiple births are counted as one<unk>  and birth. A woman who has never been pregnant is referred to as a nulligravida. A woman who is (or has been only) pregnant for the first time is referred to as a primigravida, and a woman in subsequent<unk> es as a multigravida or as multiparous. Therefore, during a second<unk>  a woman would be described as<unk> ida 2, para 1 and upon live delivery as<unk> ida 2, para 2. In-progress<unk> es, abortions, miscarriages and/or stillbirths account for parity values being less than the<unk> ida number. In the case of a multiple birth the<unk> ida number and parity value are increased by one only. Women who have never carried a<unk>  more than 20 weeks are referred to as nulliparous. A<unk>  is considered term at 37 weeks of gestation. It is preterm if less than 37 weeks and postterm at or beyond 42 weeks of gestation. American College of Obstetricians and Gynecologists have recommended further division with early term 37 weeks up to 39 weeks, full term 39 weeks up to 41 weeks, and late term 41 weeks up to 42 weeks. The terms preterm and postterm have largely replaced earlier terms of premature and postmature. Preterm and postterm are defined above, whereas premature and postmature have historical meaning and relate more to the infant's size and state of development rather than to the stage of<unk> .
