What is the expected fundus position at week 16 of pregnancy?

At week 16 of pregnancy, the expected fundus position is just above the pubic symphysis. This timing corresponds to the stage of fetal development and the growth of the uterus. During the first trimester, the uterus remains within the pelvic cavity, which is why it does not rise significantly above the pubic bone until around week 12. By week 16, as the uterus continues to enlarge and expand, it shifts into the abdominal cavity, but it is still relatively low, just above the pubic symphysis, which is an important landmark for assessing the growth and positioning of the uterus during pregnancy.

Knowing fundal height helps assess fetal growth and development, guiding further care throughout the pregnancy. Fundal height measurements become more significant in later stages of pregnancy. While the umbilical region is reached later in the pregnancy around week 20, the fundal height at week 16 is lower than that. The other options indicate fundal heights that would typically occur much later in gestation, reflecting an understanding of uterine growth patterns and timing.
