Pregnant, how to distinguish between upper and lower pregnancy?

Patient's question:

No

Doctor's answer:

People who carry high generally have a posterior uterus, while those who carry low generally have an anterior uterus! During pregnancy, the distance from the lower edge of the placenta to the internal cervical os is used to determine whether it's a high carry (greater than 7 cm) or a low carry (less than 7 cm). Carry the pregnancy accordingly and undergo regular prenatal check-ups.
