The fetal transverse position is related to many factors: 1. During the growth of the fetus, there is more amniotic fluid inside the uterine cavity, so the fetus is like swimming, which may be caused by the small size of the fetus, too much amniotic fluid and too much space to move. If the fetus is in transverse position, it cannot be delivered by normal delivery and can only be delivered by cesarean section.2. It may also be caused by uterine abnormalities, if the pregnant woman has congenital uterine malformations, it is easy to cause the fetus to be in transverse position, such as bicornuate uterus, uterine longitudinal septum, etc.3. It is also possible that the uterus is loose after the delivery of the first child, so when the second child is conceived, it is easy to appear in transverse position. It is also necessary to go to the hospital for a timely examination. 4. It may also be caused by abnormal amniotic fluid, so you should go to the hospital regularly to check the amount of amniotic fluid.
