Question 1

fundal height is 4 weeks more than my due date but baby measuring 2 weeks smaller than my due date, what does this mean?

Accepted Answer

It means little: Fundal height generally approximates but does not always correlate to the actual gestational age. The measurement that you describe, I am assuming, is an ultrasound that is also an approximation.

Question 2

when do doctors begin measuring fundal height? is it reliable before 20 weeks?

Accepted Answer

About 12 weeks: It begins to peek out from under the bones in your abdomen and it's height can be followed.

Question 3

30 week fundal height measuring 32 weeks , is something wrong ? will baby come early ?

Accepted Answer

Nonspecific: If your dates are good stick with 30 weeks.  If not so sure split the difference 31 weeks.  The fundal height is subject to interpretation and not specific.  It is just a general idea.

Question 4

diagnosed my baby fetal macrsomia. i'm 33wks+5 and fundal height measuring 37 wks. ultrasound at 2 wks ahead. have no risk factors. should i worry?

Accepted Answer

Macrosomia: Every baby grows at slightly different rates. U/S measurements are "dated" on an average growth rate, so any given time may be larger or smaller than average, but still be normal.  Sometimes, the U/S may be correct, but since bleeding can occur with pregnancy, you may just have gotten pregnant a month earlier than you calculated.

Question 5

what is more accurate? fundal height measurement or measuring the baby through an ultrasound? i'll be 24w tomorrow and haven't had my belly measured

Accepted Answer

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.

Question 6

baby fundal height was 38 at 38 weeks than measured 37.5 at 39 weeks? could it be because it was 2 different doctors  measuring me causing different measurements? or can baby fundal height go down? baby is head down.

Accepted Answer

As the pregnancy: progresses, in the later weeks, softening of the lower uterine segment, allows the head to move down in the pelvis. This is called engagement. As this occurs the fundal height drops in the last few weeks, as you have seen for yourself.

Question 7

how to measure fundal height?

Accepted Answer

Measuring tape: Use the centimeter side and measure from the middle of the pubic bone (place the zero there) to the top of the curve of the uterus. In general the number of centimeters is about the number of weeks once beyond about 15 weeks.

Question 8

at 10 weeks i measured 14 weeks in fundal height. my bladder was full at the time, how much would that affect how big my uterus measured?

Accepted Answer

Yes: It may have affected the measurement. I would wait until my next check. If you are still measuring more, i would suggest asking for a sonogram because your dates may be off.

Question 9

what is fundal height?

Accepted Answer

Top of the uterus: Fundal height refers to the location of the top of your uterus. This is a quick and easy way to confirm that the uterus is growing normally. We start at the top of the pubic bone and use the tape measure to locate the top of the uterus. After 20 weeks this distance in centimeters roughly equals your gestational age. Ex: 28 CM fundal height = 28 weeks gestation.

Question 10

how do i know if my fundal height is  right?

Accepted Answer

Plus/minus 2cm: The fundal height should not vary more than two centimeters from what your gestational age is at the time. Your doctor would probably order an ultrasound to assess the situation further it you are lagging behind or measuring ahead.
