Is it normal to be cephalic in 16 weeks?

At 16 weeks of pregnancy, the fetus is still quite small and has enough room to move around, so its position can vary. While the cephalic (head-down) position is common later in pregnancy, at this early stage, it's normal for the fetus to be in any position, including breech or transverse. The baby will continue to change positions as it grows and develops.
