The menstrual period is clinically known as the puerperium, and it usually begins on the day of the baby’s birth. In general, the puerperium period starts from the day the baby is born and usually lasts for about 6 weeks, regardless of whether it is a cesarean section or a natural birth. The puerperium is a period of time during which the mother’s body is usually weak and needs time to recover the functions of her body organs and to expel the remaining bad mucus in the uterus. During the puerperium, mothers should pay attention to rest, avoid over-exertion, and exercise appropriately to promote the discharge of bad dew. During the puerperium, the mother should pay attention to personal hygiene, keep her pubic area clean and hygienic, and change sanitary products in a timely manner to avoid infections. If any obvious discomfort occurs during the puerperium, you should go to the hospital in time for treatment.
