There is no direct connection between uterine height and pelvic, clinically the uterine height of pregnant women can not be used as a diagnostic basis for judging whether the fetus is in the pelvic, and pelvic mainly through the obstetric examination to determine. Generally speaking, in 36-38 weeks the fetus will enter the pelvis, at this time the uterine height is mostly 30-35cm, but the situation of each person is not absolute, need to do more tests to clarify. Under normal circumstances, the uterine height of pregnant women changes with a certain regularity. At the end of the 12th week of pregnancy, it is 2-3cm above the pubic symphysis; at the end of the 16th week of pregnancy, it is between the pubic symphysis and the navel. At the end of the 20th week of pregnancy, it is 1-2 horizontal fingers below the umbilicus. At the end of the 24th week of pregnancy, flat on the umbilicus or 1 horizontal finger above the umbilicus. At the end of the 28th week of pregnancy, 2-3 horizontal fingers above the umbilicus. At the end of the 32nd week of pregnancy, between the navel and the xiphoid process. At the end of the 36th week of pregnancy, 2-3 horizontal fingers below the xiphoid process. At the end of the 40th week of pregnancy, between the umbilicus and the xiphoid process or slightly higher. Typical symptoms of labor entry are the pregnant woman’s self-consciousness of stomach tension and falling sensation, while the descent of the fetus will press on the bladder and rectum, frequent urination, constipation and other symptoms. In the four-step palpation method, one of the steps is to use the thumb and four fingers of the right hand to hold the fetal head above the pubic bone and shake it from side to side; if it can be shaken and the fetal head floats, the baby is not in labor. If it cannot be shaken, it means that the fetal head has articulated, i.e., it has entered the pelvis. After the fetus is in the pelvis, pregnant women should be psychologically prepared and need to go to the hospital every week to monitor the status of the fetus, such as electronic fetal heartbeat monitoring, monitoring of the pregnant woman’s blood pressure, respiration, heart rate as well as appropriate nutritional supplements. In addition, usually pay attention to personal hygiene, wash the vulva with water every day.
