It is normal for the fetus to be more than two centimeters away from the incision (intrauterine incision). If you have had a cesarean section and are pregnant again and your gestational sac is more than two centimeters away from the uterine incision, your life will not be in danger and you may continue with your pregnancy. If the attachment position is in the uterine scar or less than two centimeters away from the scar, with the gradual growth of the gestational sac or the fetus, there is a possibility of rupture of the incision site, hemorrhage, and so on, seriously endangering the life of the pregnant woman, and it is not possible to continue the pregnancy, and it is necessary to hospitalize as soon as possible to terminate the pregnancy, and fatal hemorrhage may occur during the termination of pregnancy, which poses a great danger to the patient’s life. Women with a history of cesarean section who become pregnant again need to seek medical attention as soon as possible to determine through ultrasound whether the location of the attachment of the gestational sac is normal.
