Question: Can the scan due date be wrong?

It is very common when scanning an early pregnancy to find that the due date does not match the menstrual history. Sometimes the dates can be more than a week off and sometimes even as much as 4 weeks.

Can ultrasounds be wrong about due date?

As pregnancy progresses, the accuracy of an ultrasound for predicting due dates decreases. Between 18 and 28 weeks of gestation, the margin of error increases to plus or minus two weeks. After 28 weeks, the ultrasound may be off by three weeks or more in predicting a due date.

How accurate is due date by scan?

How accurate is the ultrasound examination? The earlier the ultrasound is done, the more accurate it is at estimating the babys due date. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 - 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

Does baby move alot before labor?

Your baby moves less: Women often notice that their baby is less active the day before labor begins. No one is sure why. It may be that the baby is saving up energy for the birth.

What is a silent labor?

Its thought that their womb (uterus) contracts so painlessly that they dont feel the contractions in the first stage of labour at all. If this happens to you, the first clue that your baby is on his way may only come as you enter your second stage of labour.
