In the later stages of pregnancy, the cervix may already have opened up to 1–3 cm (or more in rarer circumstances), but during labor, repeated uterine contractions lead to further widening of the cervix to about 6 centimeters. From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with ...

Ectopic pregnancy is a complication of pregnancy in which the embryo attaches outside the uterus. [5] Signs and symptoms classically include abdominal pain and vaginal bleeding, but fewer than 50 percent of affected women have both of these symptoms. [1]
[35] [36] The second phase of labor begins when the cervix has dilated to 10 cm (4 in), which is regarded as its fullest dilation, [31] and is when active pushing and contractions push the baby along the birth canal leading to the birth of the baby. [34]
Dilation is described using centimetres; closed, 1cm, 2cm, 3cm, etc until fully dilated at 10 cm. Fetal station −3 −2 −1, 0 +1, +2 Fetal station describes the position of the fetus's head in relation to the distance from the ischial spines, which are approximately 3-4 centimetres inside the vagina and are not usually felt.

The term postterm pregnancy is used to describe a condition in which a woman has not yet delivered her baby after 42 weeks of gestation, two weeks beyond the usual 40-week duration of pregnancy. [150] Postmature births carry risks for both the mother and the baby, including meconium aspiration syndrome, fetal malnutrition, and stillbirths. [151]
The latent phase is defined by cervical dilation of 0 to 6 cm. The active phase is defined by cervical dilation of 6 cm to 10 cm. Second stage of labor starts when the cervix is dilated to 10 cm and finishes with the birth of the baby. This stage is characterized by strong contractions and active pushing by the mother.
It is approximately 1.5 centimetres (5 ⁄ 8 inch) in diameter in newborns after 35 weeks of gestational age, [7] and 2.5–3 cm (1– 1 + 1 ⁄ 8 in) in diameter in adults. On abdominal X-rays , the small intestine is considered to be abnormally dilated when the diameter exceeds 3 cm. [ 8 ] [ 9 ] On CT scans , a diameter of over 2.5 cm is ...
