Women may experience irregular menstruation after giving birth, mainly due to the imbalance of estrogen and progesterone levels in women’s body, which is a physiological phenomenon. It is also possible that the uterus is not recovering well, which may also cause this situation. It is best to go for gynecological ultrasound and hormone examination to clarify the cause. You can adjust your lifestyle by first getting enough sleep and not doing too much physical labor. You can also adjust your menstrual cycle by consuming foods with high phytohormone content, such as soybeans, which contain a lot of phytoestrogens. In addition, women’s endocrine secretion is not stable enough after childbirth, and this is the time to pay attention and be alert if there is a long period of no future menstruation, especially during breastfeeding, when it is just as possible to get pregnant. Therefore, if you do not have a period during breastfeeding, you should pay attention to whether you are pregnant and go for pregnancy-related tests early.
