'''Pregnancy''' ([[latin]] "graviditas") is the carrying of one or more offspring, known as a [http://en.wikipedia.org/wiki/Fetus fetus] or [http://en.wikipedia.org/wiki/Embryo embryo], inside the uterus of a [[female]]. In a pregnancy, there can be multiple [http://en.wikipedia.org/wiki/Gestation gestations], as in the case of twins or triplets. [[Human]] pregnancy is the most studied of all [http://en.wikipedia.org/wiki/Pregnancy_(mammals) mammalian pregnancies]. [http://en.wikipedia.org/wiki/Obstetrics Obstetrics] is the surgical field that [[studies]] and cares for high risk pregnancy. [http://en.wikipedia.org/wiki/Midwifery Midwifery] is the non-surgical field that cares for pregnancy and pregnant women.

[http://en.wikipedia.org/wiki/Childbirth Childbirth] usually occurs about 38 weeks after conception; i.e., approximately 40 weeks from the last normal menstrual period (LNMP) in humans. The World Health Organization defines normal term for delivery as between 37 weeks and 42 weeks. The calculation of this date involves the assumption of a regular 28-day menstrual cycle.

One [[scientific]] term for the [[state]] of pregnancy is gravid, and a pregnant [[female]] is sometimes referred to as a [http://en.wikipedia.org/wiki/Gravidity gravida].[1] Neither [[word]] is used in common [[speech]]. Similarly, the term "[http://en.wikipedia.org/wiki/Parity_(medicine) parity]" (abbreviated as "para") is used for the number of previous successful live births. Medically, 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 as a "primigravida", and a woman in subsequent pregnancies as a multigravida or "multiparous".[2][3][4] Hence, during a second pregnancy a woman would be described as "gravida 2, para 1" and upon live delivery as "gravida 2, para 2". An in-[[progress]] pregnancy, as well as [[abortion]]s, miscarriages, or stillbirths account for parity [[values]] being less than the gravida [[number]], whereas a multiple birth will increase the parity value. [[Women]] who have never carried a pregnancy achieving more than 20 weeks of gestation age are referred to as "nulliparous".[5] The medical term for a woman who is pregnant for the first time is primigravida.[6]
