How to accurately calculate gestational age
Pregnancy is something every woman dreams of, but during pregnancy, there are many things to consider, such as accurately calculating the gestational age and keeping abreast of the baby\’s development. So how to accurately calculate gestational age? The following is elaborated from four aspects.
1. Last menstrual period method (LMP method)
The most common method of calculating gestational age is the last menstrual period method, which is based on the first day of a woman\’s last menstrual period. In the LMP method, the first day of the last menstrual period is used as the starting point for calculating gestational age. The number of weeks of gestation is calculated, and then added to the number of days, the current pregnancy period can be obtained.
2. B-ultrasound method
The B-ultrasound method calculates gestational age based on the fetal size and development obtained from maternal B-ultrasound examination. Through B-ultrasound examination, the fetus\’ head circumference, abdominal circumference, femoral length and other data can be measured to accurately calculate the gestational age. Especially in early pregnancy, because the fetal development is not yet obvious, the data obtained through B-ultrasound examination is more accurate.
3. Fetal movement method
During pregnancy, the baby\’s fetal movements will gradually increase, and the timing of fetal movements will become more and more regular. Therefore, by observing the frequency and pattern of the baby\’s fetal movements, the gestational age can also be calculated. Generally speaking, fetal movements around 18 weeks are relatively regular, and the gestational age can be calculated by observing the frequency of fetal movements.
4. Blood drawing method
After pregnancy, a hormone called chorionic gonadotropin (HCG) appears in the blood of pregnant women. By taking a blood sample from a pregnant woman and detecting the HCG content, the gestational age can be calculated more accurately. The higher the HCG content, the longer the gestation period.
Understand your baby’s development
In addition to accurately calculating gestational age, it is also very important to understand the development of the baby. This is explained from three aspects.
1. Fetal weight and length
During pregnancy, the baby\’s weight and length gradually increase, and the development of various organs also continues. By regularly checking the growth of fetal weight and length, you can understand your baby\’s development and detect abnormalities in time.
2. Fetal heart rate monitoring
Through fetal heart rate monitoring, you can understand the baby\’s heart rate and rhythm, and detect abnormalities in the fetal heart rate in a timely manner. Currently, fetal heart rate monitoring is very common during pregnancy and is very important to ensure the healthy growth of the baby.
3. Amniotic fluid index examination
The amniotic fluid index test is to obtain the amount of amniotic fluid around the baby through B-ultrasound examination, and can detect whether there is too much or too little amniotic fluid. Polyhydramnios may cause fetal distress, while oligohydramnios may affect the baby\’s development.
How to know the health status of the fetus in time
During pregnancy, it is crucial to ensure the healthy growth of the fetus. The following describes how to keep abreast of fetal health status from two aspects.
1. Regular prenatal check-ups
During pregnancy, regular prenatal check-ups are very important. Through regular prenatal check-ups, the baby’s development can be detected and timelydetect abnormal situations to ensure the healthy growth of the baby.
2. Physical examination during pregnancy preparation
Before pregnancy, a physical examination is also very important. Through physical examination, you can understand your own physical condition, detect certain diseases in time, and prevent any impact on your baby\’s health.
Summary
During pregnancy, it is very important to accurately calculate the gestational age and understand the development of the baby. Gestational age can be accurately calculated through methods such as the last menstrual period method, B-ultrasound method, fetal movement method, and blood drawing method. In terms of understanding the baby\’s development, methods such as fetal weight and length, fetal heart rate monitoring, and amniotic fluid index testing can be used. In addition, it is also very important to keep abreast of the health status of the fetus during pregnancy. This purpose can be achieved through regular prenatal check-ups and physical examinations during pregnancy preparation.
