For Miuparents who are waiting for two lines on the test pack or have just been declared pregnant, one question that almost always arises is: “How many weeks pregnant am I?” Especially in this era, when information about pregnancy is so easily accessible, calculating gestational age is an important thing that is often discussed early on.
Knowing how to calculate gestational age is not just a matter of numbers, but also helps Miumom understand body changes, prepare mentally, and plan for the baby’s needs early on. Let’s discuss it together in an easy-to-understand way.
When is the gestational age calculated?
Many people think that the gestational age is calculated from the moment of fertilization. In fact, medically, the gestational age is calculated from the first day of the last menstrual period (HPHT). Why not from the day of fertilization? Because the time of conception is often difficult to ascertain accurately.
By calculating from HPHT, doctors can estimate the gestational age and estimated day of birth (HPL) more consistently. So, even though Miumom is just experiencing signs of pregnancy such as nausea, missed periods, or feeling tired quickly, the gestational age could have entered several weeks.
In the young pregnancy phase, many Miumoms are surprised because they feel “just found out they are pregnant”, but it turns out that the pregnancy is already 4-6 weeks old.
Frequent signs of pregnancy in early pregnancy
Before calculating the gestational age, Miumom usually starts to suspect that she is pregnant because of the following signs of pregnancy:
- Late period
- Nausea and vomiting, especially in the morning
- Breasts feel more sensitive
- Easy fatigue and drowsiness
- Mood changes
- More frequent urination
Every mother can feel different signs. Some immediately feel severe nausea, there are also those who only realize they are pregnant after the test pack shows a positive result. This is where the importance of calculating the gestational age so that Miuparent can be better prepared for the process. You can use the Miubaby Pregnancy Calculator Generator

Knowing your gestational age early on provides many benefits, both for mom and baby-to-be:
1. Helps monitor fetal development
Each week of pregnancy has different stages of development. By knowing the gestational age, Miumom can understand what is happening to the fetus.
2. Determine pregnancy control schedule
Regular check-ups with a doctor or midwife are usually adjusted to the gestational age.
3. Prepare for physical and mental needs
From nutritional intake, light exercise, to mental preparedness, everything can be planned better.
4. Planning for baby’s needs early
Many modern Miuparents start preparing baby gear as early as the second trimester, including diapers, clothes, and other supplies.
How to Calculate Pregnancy Age Easily

There are several ways to calculate pregnancy age that Miumom can do:
1. Using the first day of your last menstrual period (HPHT)
This is the most common way. Count the number of weeks from the first day of your last period to today. Example: If the HPHT was January 1 and it is now February 1, then the gestational age is about 4 weeks.
2. Using the Naegele Formula
This formula is usually used to estimate the day of birth:
- Add 7 days from HPHT
- Reduce 3 months
- Add 1 year
Apart from determining the HPL, this formula also helps to estimate the gestational age.
3. Ultrasound examination
Ultrasound is the most accurate way, especially if Miumom forgets her HPHT date or has an irregular menstrual cycle. The doctor will measure the size of the fetus to determine the gestational age.
