A pregnancy in the third trimester requires a decision to continue the pregnancy or to have an abortion, depending on your situation. Generally, pregnant women who have had a normal delivery in the previous pregnancy and find themselves pregnant again after three months may have the option to continue the pregnancy until delivery. If the previous pregnancy was delivered by cesarean section, early termination of pregnancy is recommended. If a pregnant woman who has had a normal delivery has resumed normal ovulation after three months, she may choose to continue the pregnancy when her uterus has recovered and her body is in good condition, but she should pay more attention to her diet, behavior and maternity checkups to prevent fetal abnormalities. In addition, pregnancy in the third trimester after delivery, the woman’s milk secretion decreases, which has a certain impact on the feeding of the first-born baby and requires the timely addition of milk powder to meet the baby’s demand. Pregnant women whose previous child was delivered by cesarean section, the scar existing on the uterus will not be fully recovered in a short time, and as the pregnancy week increases, the uterus will also gradually increase in size and the uterine wall will gradually become thinner, which can lead to rupture at the scar and cause uterine rupture, which may be life-threatening. It is recommended that such pregnant women have an abortion to terminate their pregnancy as soon as possible. Medical abortion may affect the quality of breast milk and is generally not recommended. Breastfeeding is not the best time to get pregnant and it is recommended that postpartum women have good contraceptive measures when having intercourse. If there is a need to have children, you need to wait until your body recovers before preparing for pregnancy.
