Bagaimana Cara Menghitung Usia Kehamilan Secara Manual

There is no woman who does not crave pregnancy especially after marriage. Pregnancy is the mostly-awaited moment. Currently, Mommy can easily identify whether she is pregnant by using a pregnancy test pack which can be bought in pharmacies. However, for the accuracy of the results and calculate the age of pregnancy, Mommy still needs to see a doctor.

However, is there any way that can be done to determine the age of pregnancy easily and quickly? Of course it would be much better if the mommy does not need to immediately see a doctor. Therefore, knowledge of pregnancy is very important, so that mommy could control the development of the pregnancy itself. There are several ways that can be used to determine age of pregnancy quickly. 

The simplest thing to do is to calculate using a method of last menstruation. This method uses the Negele formula. This formula can be used to estimate the age of pregnancy. Moreover, this formula can also be used to estimate the date of birth.

Using a formula to calculate the age of pregnancy is identified by the last month of menstruation period. If the last menstruation period was in January to March, this formula can be used. Simply add the last date of menstruation by 7, subtract the last month of menstruation by 3, and add the last year of menstruation by 1. 

This calendar-based calculation method can be used for women with regular menstrual cycles. However, this method will not provide accurate results when applied to women with irregular menstruation cycles. For Mommies with irregular menstrual cycles, Mommies need to use another calculation method.

Another method that can be used is the detection of fetal movement. When Mommy can feel the fetal movement, mommy must already have entered Week 18-20 of pregnancy. This method can be used especially for women who are pregnant for the first time. For the next pregnancy, the fetal movements are possibly felt at Week 16-18. 

Another method of calculating the age of frequency is Fundus Uteri Method or the top of uterus. The top of the uterus of pregnant women is prominent in the abdominal wall. The age of pregnancy can be calculated by measuring the distance of the pubic bone and the top of the uterus. Every centimeter distance showed pregnancy in a matter of weeks. However, the maximum distance that can be measured is only 36 cm. Good luck!
