How to accurately determine the length of your pregnancy
It is very important for expectant mothers to accurately determine the length of their pregnancy. This is because the length of pregnancy is directly related to the prediction of the date of delivery and the development of the fetus. So, how to accurately determine the length of your pregnancy? Next, we will elaborate on it from four aspects.
Aspect 1: Menstrual cycle
A woman\’s cycle before conception lasts 28 days. According to cycle statistics, ovulation is usually around 14 days of the menstrual cycle. Therefore, if an expectant mother can determine the starting date of her conception, she can calculate the duration of her pregnancy by adding and subtracting. The specific method is: minus 14 days is the ovulation day, plus 14 days is the conception day; and 280 days after conception is the standard length of pregnancy.
Aspect 2: B-ultrasound examination
B-ultrasound examination is an effective method for expectant mothers to determine the length of pregnancy. Under normal circumstances, doctors will perform a B-ultrasound examination in the first trimester, so that they can accurately understand the development of the fetus and the number of days of pregnancy. Mothers can also determine the length of pregnancy by checking the fetal heartbeat, head circumference, abdominal circumference and length and other size data.
Aspect Three: Fetal Movement Observation
As the fetus develops, pregnant women will also feel fetal movement. Under normal circumstances, pregnant women can feel fetal movements around 18 weeks of pregnancy. As the number of fetuses increases, the duration of fetal movements will gradually lengthen. Therefore, by observing indicators such as the frequency, duration, and intensity of fetal movements, the length of pregnancy can be initially estimated.
Aspect 4: Accurate calculation method
The exact method is used to calculate the length of pregnancy by counting the exact days after conception. This method is more troublesome and requires a more accurate grasp of your menstrual cycle. Generally speaking, expectant mothers can take a pregnancy test about 14 days after conception, and then contact the start date of their last menstrual period to more accurately calculate the length of their pregnancy.
Summary
The above four aspects are all effective ways to accurately determine the length of pregnancy. However, each method has certain errors, so the most accurate judgment method should be to comprehensively consider multiple methods, find common points, and confirm each other. If an expectant mother is unsure about the length of her pregnancy, it is best to consult a doctor promptly and listen to professional opinions and suggestions in order to make the right decision.
