Is it normal to have delayed menstruation during breastfeeding?

Many friends who are new mothers do not understand the body’s recovery process. When their menstruation is delayed, they are always worried that there is something wrong with their body. In fact, this is normal and there is no need to worry or be nervous. The timing of menstruation after childbirth actually varies from person to person. Some friends will not have menstruation during breastfeeding, so you need to learn more about this.

Is it normal to have delayed menstruation during breastfeeding?

In fact, menstruation during breastfeeding is a very normal physiological phenomenon. There are obvious individual differences in the timing of menstruation after delivery. Some women may have menstruation after a full month if their menstruation resumes early, while others may not have menstruation resume until the baby is one year old. Generally speaking, mothers who do not breastfeed usually have their "old friend" 6-10 weeks after giving birth. The recovery time of menstruation for breastfeeding mothers is generally delayed, and some mothers do not have their menstruation at all during the breastfeeding period.

From a medical point of view, based on the tissue morphology of the endometrium, the ovaries may be able to ovulate as early as 33-42 days after delivery. Research data show that 40% of non-breastfeeding mothers resume ovulation 6 weeks after delivery. By 8-12 weeks after delivery, only about 35% of women have not resumed ovulation and menstruation. About 25% of breastfeeding mothers will resume ovulation and menstruation 12 weeks after delivery, and most breastfeeding mothers usually take until 18 weeks to fully resume ovulation function.

However, it is sometimes difficult to clinically determine the exact time of the first menstrual period after delivery, and a small number of women will begin to have intermittent bleeding of small to moderate amounts immediately after delivery.

There is a folk saying that if menstruation comes during the breastfeeding period, breast milk will no longer be nutritious and may even be toxic to the baby, so the baby must be weaned. In fact, this statement is unscientific. Under normal circumstances, the quality of breast milk is best from 11 days to 4 months after delivery. After menstruation, breast milk becomes more concentrated than usual, contains less fat and more protein. This type of breast milk is not harmful to the baby.

What are the characteristics of menstruation during lactation ? 1. The first menstrual flow is heavier. Most new mothers have a heavier than usual menstrual flow the first time, but the second menstrual period becomes normal, so no treatment is needed.

2. Postpartum lochia is not menstruation. Normally, after giving birth, a woman will have bloody discharge from the birth canal, similar to menstruation. This bleeding from the placenta implantation site, mixed with secretions such as the decidua, tissue fragments, and mucus remaining in the uterus, is called lochia. Normally, in the first 4-5 days, the lochia is heavy and red. One week after delivery, the amount of lochia gradually decreases and turns brown. After the 10th day, the color becomes lighter, slowly turning from yellow to white, and there is no special smell. Lochia usually disappears 4-6 weeks after delivery. But sometimes a small amount of brown lochia will continue until the first menstrual period after delivery. Lochia generally does not exceed the amount of menstruation. If the bleeding lasts for more than two weeks, exceeds the menstrual volume or contains blood clots, or the vaginal discharge appears as rotten meat-like tissue or has a foul odor, you should seek medical attention immediately.

3. Irregular menstrual cycle. Generally speaking, irregular menstruation during breastfeeding is normal. This is caused by endocrine dysfunction. Most of the time, no treatment is required and the period will gradually recover over time. Once breastfeeding stops completely, the period will gradually return to normal.
