The postpartum physiological changes are those expected changes that occur in the woman's body after childbirth, in the postpartum period. These changes mark the beginning of the return of pre-pregnancy physiology and of breastfeeding .
The delayed postpartum period starts after the subacute postpartum period and lasts up to six months. [10] During this time, muscles and connective tissue returns to a pre-pregnancy state. Recovery from childbirth complications in this period, such as urinary and fecal incontinence , painful intercourse , and pelvic prolapse , are typically ...
For example, if there is a gestational age based on the beginning of the last menstrual period of 9.0 weeks, and a first-trimester obstetric ultrasonography gives an estimated gestational age of 10.0 weeks (with a 2 SD variability of ±8% of the estimate, thereby giving a variability of ±0.8 weeks), the difference of 1.0 weeks between the ...
The perinatal period (from Greek peri, "about, around" and Latin nasci "to be born") is "around the time of birth". In developed countries and at facilities where expert neonatal care is available, it is considered from 22 completed weeks (usually about 154 days) of gestation (the time when birth weight is normally 500 g) to 7 completed days ...

Due dates are easily miscalculated when the mother is unsure of her last menstrual period. When there is a miscalculation, the baby could be delivered before or after the expected due date. [23]
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
