The fetus is early to enter the pelvis at 30 weeks of pregnancy and there is a possibility of preterm delivery, but there are also cases of full-term delivery at 30 weeks, which should be closely observed and dealt with in different situations. Fetal pelvic entry is one of the signs of maternal delivery, which means that the fetus enters the pelvic cavity through the entrance of the pelvis. The time of pelvic entry can be early or late, a few people will be in pelvic entry before delivery, while others will not be in pelvic entry until the birth, most first-time mothers will show signs of pelvic entry at 34 weeks of pregnancy, while women in labor will gradually enter pelvic entry as labor progresses, usually at about 36 weeks. If the fetal head is already in the pelvis at 30 weeks of pregnancy, the patient should be alert to the possibility of preterm labor and should go to the hospital for an abdominal ultrasound to clarify the specific situation. If there is increased vaginal discharge, redness and abdominal pain, the patient should immediately call 120 for medical attention and stay in bed until the ambulance arrives. If there are uterine contractions, you can use medication to inhibit them under the guidance of the doctor and try to keep the fetus until after 34 weeks of pregnancy. If the fetal head is simply in the pelvis and the opening of the cervix is not open and the cervical canal is not shortened, it is possible to hold on to the baby until after 36 weeks and there is no need to worry too much.
