Baby growth: The fundal height is good for trending over the course of your pregnancy and fh is +/- 2-4 cm = weeks once past 20 weeks. Most doc's will start measuring fh at 20 or 24 week visit. U/s has a 10-15% error of calculating baby weight throughout pregnancy and assigning dates varies with gestational age.
