At 30 weeks of pregnancy, the fetus is mostly in the mother’s womb in a longitudinal birth position with the head in the mother’s pelvic position and the buttocks above the mother’s uterus. The fetal position in which the head is in the mother’s pelvic position and the fetal buttocks are above the mother’s uterus is called cephalic, and cephalic is the most common fetal position. In a small percentage of cases, the baby’s buttocks are located in the mother’s pelvis and the baby’s head is above the mother’s uterus, which is called breech presentation. Both cephalic and breech presentation are known as longitudinal labor and are relatively common fetal positions. A small percentage of fetuses, at 30 weeks gestation, are in a transverse position in the mother’s uterus, which means that the fetus’s arms or shoulders are in the mother’s pelvic position and the head or buttocks are on either side of the mother’s uterus, a position that may cause difficult labor during delivery and requires prompt management. Fetal position at 30 weeks of pregnancy is not fixed, no matter what position fetal position, should be on time obstetric examination, follow the doctor’s advice to deal with.
