  • The first few weeks of pregnancy are critical to the development of the fetus. For this reason, it is important to know the expected due date.
  • A normal pregnancy can last anywhere from 38 to 42 weeks. It is also considered normal for a woman to give birth 3 weeks before or 2 weeks after the calculated delivery date.

The expected date of delivery

All relevant information is only an estimate. Calculating the expected delivery date is not an exact science. According to statistics, only 5.54% of births occur exactly on the estimated due date. Because every pregnancy is unique. In fact, most babies are born a week before or a week after their expected due date. This means that around 95% of children are not born when they are expected.

It is normal for a woman to give birth two weeks after the due date or even three weeks beforehand. This is the case with 95% of all children born in the world. Nine percent of children are born prematurely. Premature birth is when a child is born more than three weeks before the due date. Children born two weeks after the calculated due date are said to be born late. This corresponds to about 1% of the total population.

Calculation of your pregnancy according to Naegele's rule

The Naegele rule, named after Dr. Franz Karl Naegele, is one of the standard methods for calculating your due date.
You can get the result by adding about 281 days (40 weeks) from when you last menstruated.

How to calculate your due date

To calculate your due date, simply add 40 weeks (280 days) to the first day of your last menstrual period. This is true if you have an average 28 day cycle. But every woman is unique. Therefore, due dates are only an estimate and not an exact finding.

Also, remember that your ovulation and menstrual period are counted as the first two weeks of pregnancy. So if you give birth on the due date, your baby will actually have developed for 38 weeks, not 40 weeks.

If you are not satisfied with the way your due date is calculated, there are other ways you can set this date. Contact your doctor; using one of the following methods.

You can determine your due date based on the "first few times". Some indicators can help predict your due date. These are moments like the first time you can hear the fetus's heartbeat (weeks 9-12) or the first time you feel movement (weeks 16-22). These observations can give you an idea of ​​the expected due date.

The level of the uterus. Every time you visit a doctor during your pregnancy, your doctor will measure the highest point of the uterus. When this reaches your navel, it would mark the 20th week of your pregnancy. This clue can be used to estimate your due date.
