After a period during breastfeeding, the next month’s period may not always be on time, it may or may not be on time, it varies from person to person. After one period during breastfeeding, the next month’s period may not be on time because breastfeeding suppresses ovarian ovulation, resulting in a delay in the return of menstruation after childbirth. In addition, over-exertion after delivery and injuries caused during delivery may also affect the recovery of menstruation after delivery, resulting in the next month’s menstruation not being on time. However, if the mother recovers well, her period may also be on time. If you are breastfeeding, your period may or may not be on time next month. We suggest that you observe your period carefully, try to keep your mood relaxed, and if you have any abnormal symptoms, consult your doctor to complete the relevant examinations and standardize the treatment under your doctor’s guidance.
