Breastfeeding is a special physiological period for women, who are weak after giving birth and whose bodies need to recover slowly. During breastfeeding, lactogen increases and suppresses the secretion of estrogen, which can affect menstruation. The time of menstruation varies from individual to individual, most of them will resume menstruation in about 6 months after giving birth, among women who are fully breastfeeding, 1/3 of them will resume menstruation within 3 months after giving birth, the earliest in 8 weeks after giving birth, and some are slow to recover and will have menstruation only in about a year to a year and a half after giving birth. It is very common for women to be weak after childbirth, and it is normal for them not to have their periods, so don’t worry too much. So breastfeeding is an important period for women to recover their bodies, they need to pay attention to their diet and life, and must pay attention to adequate rest and regular rest and rest. Another point that needs special attention is that even if you do not have a period during breastfeeding, you will still ovulate and get pregnant normally. Men can use condoms, women can use vaginal contraceptive diaphragms, oral contraceptives are not recommended to avoid the metabolism of drugs through breast milk, affecting the development of the baby.
