The claim that “the earlier the menstruation is, the better” lacks scientific basis, there is no good or bad, it is just a physiological phenomenon. The earlier the menstruation comes, the better it is. The early or late menstruation after normal delivery is determined by a variety of factors, such as personal constitution, endocrine level, environmental factors, whether or not to breastfeed, etc. Early menstruation does not mean that the body recovers better, and late menstruation does not mean that the body is worse than others. If you are breastfeeding or not, for example, if you are breastfeeding after childbirth, your period will return to normal only after you stop breastfeeding because lactogen inhibits ovulation, while if you are not breastfeeding, your period will come early. Therefore, it should be analyzed on a case-by-case basis, and mothers should not be too concerned about it. After a normal birth, if the situation allows, the mother should try to breastfeed, breast milk has an irreplaceable role in the growth and development of the child. The mother should pay attention to nutritional supplements, emotional stability and physical health to ensure that her body quickly recovers to the prenatal period. If menstruation does not resume after breastfeeding, it is best to go to the hospital for examination to clarify whether treatment is needed.
