There is still milk after breastfeeding pregnancy, but it will gradually decrease and usually disappear after about 3-4 months. It is not recommended to continue breastfeeding your baby after breastfeeding pregnancy because the quality of milk is gradually decreasing and the fetus in the womb also needs a lot of nutrition, so breast milk at this time can no longer meet the needs of the baby’s growth and development. The hormone level in the body will change during pregnancy and the milk will be reduced, so it is recommended to add formula or complementary feeding to the baby. It is generally recommended that strict contraceptive measures be taken during breastfeeding, because if breastfeeding leads to unintended pregnancy, the following hazards are likely to occur: 1. pregnancy after the body organs and tissues have not fully recovered during breastfeeding, when the embryo has been laid in the uterus, the old wounds of the uterus have not yet healed, which will cause damage to the recovery of the female uterus, and will also easily lead to accidents during childbirth; 2. 2, lactating women’s body nutrition is not enough to bear the needs of pregnancy, at this time pregnancy may cause fetal malnutrition, but also easily lead to female body weakness, resistance to decline, increasing the risk of fetal and maternal postpartum bleeding, infection; 3, caesarean section women’s uterine wall wound is difficult to heal within a short period of time, if pregnant during lactation, as the fetus gradually grows, it is easy to stretch the uterine wall to its thinning, the surgical wound of the uterine wall in the middle or late pregnancy is easy to cause pregnant women The surgical wound of the uterine wall in the middle or late pregnancy can easily cause hemorrhage to the pregnant woman, which is harmful to the fetus and pregnant woman.
