Hello Oktaviani,


Fundal height (TFU) is one of the tests performed during pregnancy control. TFU examination is useful to help calculate gestational age and fetal development. However, to ensure the condition of pregnancy, not only from the TFU, but also from the results of ultrasound and maternal health checks.


TFU measurement can be used to predict gestational age by entering it in the formula mc donald = age (in weeks) x 8/7. TFU 27 cm is likely 30-31 weeks gestation. The presence of a TFU that is smaller than normal as you experience can be influenced by several factors such as:

The fetus enters the pelvis or the fetus is small in size
Abnormal fetal position, for example, a transverse position
Short or thin mother
Stunted fetal growth
Amniotic fluid is low
The bladder is full on examination

To measure the estimated fetal weight, it is necessary to do an ultrasound first. At 29 weeks of gestation, the fetus weighs 1.4 kg in normal limits. Whereas for 34 weeks of age, the estimated fetal weight is normally about 2.1 kg with a length of 45 cm.


If you want to know the estimated fetal weight, you can consult your obstetrician so that an ultrasound is done first. In addition to knowing the estimated fetal weight, ultrasound is also performed to determine the condition of the amniotic fluid, placenta, umbilical cord, fetal position, fetal heart rate, and detect abnormalities in the fetus. You can do an ultrasound 2 weeks after the last pregnancy control. After entering term of age / more than 37 weeks, pregnancy control can be done once a week.


We recommend that you keep your intake of nutrients and fluids during pregnancy, get adequate rest, avoid stress, and start in installments to prepare for the needs of labor and the needs of your baby.
