The arching of the lumbar region is known as lumbar lordosis, which recovers the center of mass into a stable position by reducing hip torque. According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% ...
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of childbirth .
Knowledge about birthing positions can help mothers choose the option they are most comfortable with. Having the agency and self-control to change positions in labor positively influences the mother's comfort and birthing experience, which increases the birthing outcome and her satisfaction with labor.

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. [152] Postmature births carry risks for both the mother and the baby, including meconium aspiration syndrome, fetal malnutrition, and stillbirths. [153]
Fetal position (British English: also foetal) is the positioning of the body of a prenatal fetus as it develops. In this position, the back is curved, the head is bowed, and the limbs are bent and drawn up to the torso. A compact position is typical for fetuses. Many newborn mammals, especially rodents, remain in a fetal position well after birth.
By about week 21, the fetus begins to develop a regular schedule of movement. [17] The startle reflex is present in half of all fetuses by week 24 and in all fetuses by week 28. [19] Movement is restricted around this time because the fetus has grown so large it has little space for kicking or changing body position. [20]

The first ten weeks of gestational age is the period of embryogenesis and together with the first three weeks of prenatal development make up the first trimester of pregnancy. From the 10th week of gestation (8th week of development), the developing embryo is called a fetus.
