Your question: How accurate is belly measurement during pregnancy?

How accurate are belly measurements in pregnancy?

The measurement is generally defined as the distance in centimeters from the pubic bone to the top of the uterus. The expectation is that after week 24 of pregnancy the fundal height for a normally growing baby will match the number of weeks of pregnancy — plus or minus 2 centimeters.

Can fundal height be wrong?

If your fundal height isn’t what you expect it to be, it doesn’t automatically mean that there’s something wrong with your baby. But if your fundal height is on track, you may be able to rest a little easier knowing your baby is growing the way your doctors are expecting it to.

Does fundal height indicate baby size?

But does fundal height indicate baby size only? Nope! The fundal height measurement also provides your doctor with a way to track your baby’s position, and the amount of amniotic fluid there is in your uterus.

Does the size of the belly determine the size of the baby?

What you see on the outside — the general size and shape of your belly — doesn’t have much to do with your baby, their health, or their size. A healthy baby can grow regardless of how your belly looks. During your second trimester, your doctor will start taking fundal height measurements.
