The saying that “the earlier the menstruation comes, the better” lacks scientific basis, and there is no difference between good and bad, it is just a physiological phenomenon. It is a physiological phenomenon. There are many factors involved in the onset of menstruation, and it is not true that the earlier the better. After giving birth, menstruation comes sooner or later due to a variety of factors, such as individual physical condition, endocrine level, environmental factors, breastfeeding or not, etc. Early menstruation does not mean that the body recovers better, and late menstruation does not mean that the body is worse than others. Taking breastfeeding as an example, if you breastfeed after delivery, your period will usually return to normal only after you stop breastfeeding due to the inhibition of ovulation by lactin; if you don’t breastfeed, you will have your period at a very early stage. Therefore, each case should be analyzed on a case-by-case basis, and mothers should not be overly concerned about this. If the situation permits, the mother should try to breastfeed her child, as breastmilk plays an irreplaceable role in the child’s growth and development. Mothers should pay attention to nutritional supplements, emotional stability and physical health to ensure that their bodies recover quickly to the prenatal period. If menstruation has not resumed after breastfeeding, it is best to go to the hospital for a checkup to determine whether treatment is needed.
