Generally speaking, in the first 26 weeks of pregnancy, due to the small size of the fetus, no baby’s fetal position is fixed. At this time, if the fetus is in transverse position, it may correct itself due to the large space for the fetus to move around. If the baby is still in transverse position after 30 weeks, it may be caused by pelvic stenosis. It is very difficult to correct the transverse position of the fetus due to pelvic stenosis, and the only option is to have a cesarean delivery. If the transverse fetal position is due to the mother’s pelvic stenosis, she can ask her doctor to help her change to a cephalic or breech position. It is a dangerous position for both the fetus and the mother. Even if the fetus is not in labor, this position may cause the uterus to rupture or the umbilical cord to prolapse, resulting in the death of the fetus in the uterus, which is a relatively dangerous situation.
