>Hello Sohib EditorOnline and welcome to our journal article about how to calculate pregnancy age if you forget your last menstrual period (HPHT). It is common for women to forget the exact date of their last period, especially if they have irregular periods. However, knowing the age of your pregnancy is crucial for proper prenatal care and monitoring. In this article, we will provide you with simple and accurate methods to calculate your pregnancy age. Let’s get started!
HPHT stands for “Hari Pertama Haid Terakhir” which means “the first day of the last menstrual period”. This is an important date for calculating the due date of your pregnancy. Most doctors and midwives use this date to estimate the age of the pregnancy and make sure that the baby is developing properly. However, if you forget this date, there are other methods that you can use to calculate your pregnancy age.
Method 1: Ultrasound
Ultrasound is a non-invasive and safe method to determine the age of the pregnancy. During an ultrasound, the doctor or technician will use a device called a transducer to send sound waves through your abdomen. These sound waves will bounce back and create an image of your uterus and the growing fetus. The doctor or technician will measure the size of the fetus and compare it to the standard growth charts to determine the age of the pregnancy.
Ultrasound is the most accurate method to determine the age of the pregnancy, especially in the first trimester. However, it may not be available in all healthcare facilities or may be expensive. If you cannot afford an ultrasound or if it is not available, there are other methods that you can use.
Method 2: Pregnancy Wheel
A pregnancy wheel is a circular calculator that uses the date of the last menstrual period to estimate the due date of the pregnancy. It is a simple and inexpensive method that you can use at home or in a healthcare facility. To use a pregnancy wheel, you need to know the first day of your last menstrual period and the length of your menstrual cycle.
Here’s how to use a pregnancy wheel:
Step
Instructions
Step 1
Locate the first day of your last menstrual period on the outer ring of the pregnancy wheel.
Step 2
Rotate the inner ring of the pregnancy wheel until it aligns with the current date.
Step 3
Read the due date of your pregnancy on the inner ring of the pregnancy wheel.
Keep in mind that a pregnancy wheel is an estimate and may not be accurate for all women, especially those with irregular periods. If you are unsure about the accuracy of the pregnancy wheel or if you have any concerns about your pregnancy, consult with your healthcare provider.
HCG (human chorionic gonadotropin) is a hormone that is produced by the placenta during pregnancy. The level of HCG in your blood or urine can indicate the age of your pregnancy. HCG levels are usually measured through a blood test or a urine test. However, the accuracy of HCG levels may vary depending on the individual.
Here’s how to use HCG levels to calculate your pregnancy age:
Weeks of Pregnancy
Range of HCG Levels (mIU/mL)
3-4
5-426
4-5
19-7,340
5-6
1,080-56,500
6-7
7,650-229,000
7-8
29,100-236,000
8-9
59,500-201,000
9-10
64,000-225,000
10-11
44,000-170,000
12-16
16,000-120,000
17-24
4,060-165,400
25-40
3,640-117,000
As you can see, the range of HCG levels is wide and may overlap with different weeks of pregnancy. HCG levels should be interpreted in consultation with your healthcare provider.
