How to calculate the gestational age accurately and accurately

Many pregnant women think that it is important to know the gestational age. Why Because gestational age can make pregnant women know about HPL (estimated birthday).

Unfortunately, there is no method to predict HPL in detail. Then, how to calculate the recommended gestational age? Find the following explanation.

Use LMP as a reference

There is no way to know for certain when a mother ovulates and becomes pregnant. As a result, most people, including health professionals, will calculate the gestational age based on the LMP (last menstrual period) or the last menstrual period as a reference.

To find out the gestational age for this size, try to remember when your last period began. The first day of PML is the first day of pregnancy.

Then you can find out the estimated date of birth using a calculator. What if you don't know the date of the last period or if your period is irregular?

Use analysis tools

Calculation of gestational age using the LMP method works well only if the menstrual cycle is regular and the duration of the period is every 28 days. If you have irregular menstrual cycles or if the duration of this cycle varies, the LMP method can be difficult.

In this case, you can use ultrasound analysis or dating to get more precise information about gestational age.

The scanning process using sonography involves measuring the baby from the head to the anus. This method is called Crown Rump Length (CRL). It is a good idea to do a dating analysis when the LMP is between 10 and 13 weeks.

Cases of frequent gestational age calculations

In many cases, pregnant women have difficulty understanding why their pregnancy is only four weeks, even when they enter the fifth week of pregnancy. How could this happen?

For example, when a child is 1 year old, the one-year-old child has died in his first year. By entering the second year, the new child will grow to 2 years for the following year. Thus, the child is only 1 year old even though he is entering his second year.

This also applies to pregnancy calculations. To better understand, consider the following gestational age calculations:

First week, you are 0 weeks pregnant.
By entering the second week, you are only one week pregnant.
By entering the third week, you are 2 weeks pregnant.
By entering the fourth week, you are only 3 weeks pregnant.
By entering the fifth week, you are 4 weeks pregnant.

Understand quarterly calculations

"Quarter" means "three months". Because the majority of pregnancy periods are around nine calendar months, each pregnancy is divided into three quarters. Quarters are useful for describing changes during pregnancy, for example:

First trimester (early pregnancy - 13 weeks and 6 days). During this period, fatigue and nausea usually occur.
Second trimester (14 weeks - 27 weeks, 6 days). During the second trimester, you will feel better, your body will start to bloom and your stomach will start to swell.
Third quarter (28 weeks - delivery). During this period, fatigue will occur because it requires extra energy to get ready for work.
