What is the typical fundus position at week 12 of pregnancy?

At 12 weeks of gestation, the fundus of the uterus is typically found just above the pubic symphysis. This is because during the first trimester, the uterus is still relatively small and remains within the pelvic cavity. As the pregnancy progresses, the uterus rises and begins to expand into the abdominal cavity, but by 12 weeks, it is only beginning to elevate above the pubic bone.

Understanding the growth and position of the uterus throughout pregnancy is important for monitoring fetal development and the health of the pregnancy. The positions associated with the other choices indicate a much more advanced stage of pregnancy. For instance, the fundus being at the umbilicus occurs around 20 weeks of gestation, indicating that those stages of development are not reached yet at week 12. Thus, knowing the typical fundus position at different stages helps in assessing the progression of pregnancy.
