During pregnancy, the enlarged abdomen and gravid uterus place additional strain on lumbar muscles and shift the pregnant woman's center of gravity. These postural compensations culminate in an increased load on both lumbar spinal musculature and the sacroiliac ligaments, manifesting as low back pain and/or pelvic girdle pain. [ 12 ]
A woman's uterine muscles, rather than her abdominal muscles, are first to sense fetal motion. Therefore, her body weight usually does not have a substantial effect on when movements are initially perceived. Women who have previously given birth have more relaxed uterine muscles which are more sensitive to fetal motion during subsequent ...
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% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
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.
In the early follicular phase, uterine contractions in the non-pregnant woman occur 1–2 times per minute and last 10–15 seconds with a low intensity of usually 30 mmHg or less. This sub-endometrial layer is rich in estrogen and progesterone receptors. [3] The frequency of contractions increases to 3–4 per minute towards ovulation.

Morning sickness is very common among pregnant women, which argues in favor of its being a functional adaptation and against the idea that it is a pathology. Fetal vulnerability to toxins peaks at around 3 months, which is also the time of peak susceptibility to morning sickness.
