There is no correlation between the return of menstruation after delivery and a good recovery, and it does not mean that the uterus has recovered well after delivery.
The timing of the return of menstruation is affected by a number of factors, such as whether or not the woman is breastfeeding. For women who are not breastfeeding, menstruation usually occurs within 3 months. If a woman is breastfeeding, the return of menstruation after delivery will be delayed accordingly, and menstruation may occur within 6 to 12 months.
From this, we can tell that the return of menstruation has nothing to do with good physical recovery, but women still need to pay attention to the recovery of the body, maintain a regular routine, do not stay up late. Diet should also be nutritionally sound, not picky or partial food.
With the current standard of living, most mothers can keep up with the nutrition after delivery, so their bodies can recover well, but they should also pay attention to personal hygiene to prevent infections.
