During the postpartum breastfeeding period, it is normal for mothers to experience bleeding during ovulation. Most women who bleed during ovulation are affected by fluctuations in hormone levels in the body. The bleeding usually occurs midway between two menstrual periods, and the amount of blood is relatively small and light in color. It usually returns to normal within one to two days, so there is no need to worry when ovulation bleeding occurs. It is important to rest, avoid overwork, enhance nutrition, keep warm, and avoid getting cold. During breastfeeding, it is essential to observe the amount of vaginal bleeding. If menstruation resumes, it is crucial to pay attention to contraception.
