Whether the placenta is better in the anterior or posterior wall is not comparable and there is no difference between the two. The placenta is located in the anterior wall, posterior wall, fundus, lateral wall of the uterus, etc., which are all normal pregnancy positions. If the placenta is located at the lower end of the uterus, close to or even at the cervical opening, it is classified as placenta praevia or placenta praevia. Pregnant women with placenta praevia or placenta praevia should pay extra attention throughout their pregnancy. Especially in the late stage of pregnancy, it may cause preterm labor, painless bleeding, or even endanger the life of the fetus. It is recommended that women should have regular checkups during pregnancy, maintain a happy mood during pregnancy, eat a balanced diet, exercise moderately, prevent constipation, and avoid staying up late and overworking. Women should learn to monitor fetal movement and seek medical attention if there is any abnormality.
