Gravidity and parity. In biology and medicine, gravidity and parity are the number of times a female has been pregnant (gravidity) and carried the pregnancies to a viable gestational age (parity). [ 1][ 2] These two terms are usually coupled, sometimes with additional terms, to indicate more details of the female's obstetric history. [ 3]
Pregnancy is the time during which one or more offspring develops inside a woman's uterus (womb). [4] [13] A multiple pregnancy involves more than one offspring, such as with twins. [14] Pregnancy usually occurs by sexual intercourse, but can also occur through assisted reproductive technology procedures. [6]
Gestational age. In obstetrics, gestational age is a measure of the age of a pregnancy taken from the beginning of the woman's last menstrual period (LMP), [ 1] or the corresponding age of the gestation as estimated by a more accurate method, if available. Such methods include adding 14 days to a known duration since fertilization (as is ...
The estimated date of delivery ( EDD ), also known as expected date of confinement, [ 1] and estimated due date or simply due date, is a term describing the estimated delivery date for a pregnant woman. [ 2] Normal pregnancies last between 38 and 42 weeks. [ 3] Children are delivered on their expected due date about 4% of the time.
Postpartum period. The postpartum (or postnatal) period begins after childbirth and is typically considered to last for six weeks. [ 1] There are three distinct phases of the postnatal period; the acute phase, lasting for six to twelve hours after birth; the subacute phase, lasting six weeks; and the delayed phase, lasting up to six months.
Gestation. Drawing of a fetus in utero. Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). [ 1] It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for ...
A woman pregnant for the first time (nulliparous) typically feels fetal movements at about 21 weeks, whereas a woman who has given birth before will typically feel movements by 20 weeks. [13] By the end of the fifth month, the fetus is about 20 cm (8 in) long.
However, odds of long-term survival between 22 and 23 weeks are 2–3 percent and odds of survival between 23 and 24 weeks are 20 percent. [61] "Intact survival", which means survival of a neonate without subsequent damage to organs such as the brain or bowel is 1% at 22 weeks and 13% at 23 weeks. [61]
