Young women are often the happiest women in the world after giving birth, successfully transforming into mothers. However, some women experience irregular menstruation postpartum. Many want to know the causes of postpartum menstrual irregularities. Below, an expert will explain the reasons.


What causes postpartum menstrual irregularities?

1. Breastfeeding or delayed menstruation

If a pregnant woman breastfeeds her child after delivery, it is normal for her to not have her period during the breastfeeding period. The main reason is that the level of prolactin in a woman's body tends to rise during breastfeeding. The presence of this hormone inhibits the release of eggs from the ovaries, ultimately causing menstruation to not arrive on time.

2. Cesarean section affects menstruation

If mothers have a cesarean section during delivery, the endometrium may be excessively scraped away during the surgery, causing the endometrium to not be able to repair itself in a short period of time. The end result is menstrual irregularities. Once the endometrium has recovered, the menstrual irregularities will disappear.


3. Getting pregnant again

If a woman experiences irregular menstruation after childbirth, it could be a sign of another pregnancy. It is recommended that mothers go to the hospital for relevant examinations as soon as possible. Once the examination results are available, they will know that they are pregnant again, because irregular menstruation can also occur after a second pregnancy.

4. Emotional influence

If mothers experience significant stress and fear after childbirth, their emotions can affect their endocrine system and lead to menstrual irregularities. Therefore, it is recommended that pregnant women maintain an optimistic and cheerful mood after delivery. If anxiety or depression occurs, they should talk to family and friends to avoid postpartum depression.

5. Resuming sexual activity too early

Pregnant women should avoid sexual intercourse for one month after a vaginal delivery, and for three months after a cesarean section. Some couples do not follow these guidelines and engage in sexual activity prematurely, resulting in uterine infection and inflammation, which can lead to menstrual irregularities.


After a successful delivery, proper postpartum care is essential. Avoid excessive anxiety, refrain from resuming sexual activity too early, and take good care of yourself to prevent postpartum menstrual irregularities.
