Uterus Growth During Pregnancy

In pregnancy, the uterus, also known as the womb, expands to accommodate your growing baby. During prenatal checkups, your provider will use tape to measure from the highest point of your uterus, also known as the fundus, to the top of your pubic bone, said Ellen Smead, CNM, a certified nurse-midwife at Northside Women’s Specialists, part of Pediatrix® Medical Group. This measurement is called the fundal height. Smead noted that the measurements, taken in centimeters, typically correspond with how many weeks along you are (give or take about 1 or 2 centimeters). “Women’s abdomens are certainly unique, and some people will grow constitutionally small or large babies,” said Smead. “What we want to look for is abnormally small or large measurements, and also if uterine measurement is consistent over time.”
