The second pregnancy is not always a lower pregnancy. Lower pregnancy means that the fetus is in the lower part of the pregnant mother’s stomach, usually the stomach of the pregnant mother in lower pregnancy does not look very obvious, but from the back will appear to be larger hips, and the pregnant mother will look slower when she walks. The position of the pregnancy is determined by the individual’s physical condition and the location of the fertilized egg, the location of the fertilized egg will form a lower pregnancy, usually has nothing to do with the first few pregnancies. Whether it is an upper or lower pregnancy, it will not affect the labor and delivery, and it is a normal phenomenon. Generally speaking, the uterus is more likely to press on the bowel, pubic bone and bladder in a lower pregnancy than in an upper pregnancy, which in turn causes frequent urination, pain in the pubic bone, increased discharge and constipation. Pregnant mothers should be careful not to hold back urine to avoid triggering urinary tract infections, and their diet should be light and well-balanced.
