According to most studies, only 5% babies are actually born on their pregnancy due date.

How long is the typical pregnancy?

A normal pregnancy often lasts anywhere from 38 to 42 weeks.

How is your pregnancy due date calculated?

It is estimated by subtracting or counting backwards 3 months from the 1st day of your last menstrual period (LMP), then add 7 days to it. That’s your due date the following year.

Can my pregnancy due date change?

Will my due date change when I have a scan?

How does a Pregnancy Calculator Work?

Now that you have received the good news the next big question arises – when is the baby due? Instead of making guesses or counting the days on your fingers nowadays the pregnancy calculator does the work for you.

Working of Pregnancy Due Date Calculator

Normally pregnancies last for around thirty-eight to forty weeks. The best way of estimating as to when your pregnancy is due is to count to forty weeks from the starting date of your last period. This is the method used by gynaecologists for estimating the same. But it is also important to keep in mind that it is a normal phenomenon for the delivery to take place a week or two before or after the predicted date.
The pregnancy calculator subtracts three months from the first day of your last menstrual period and then adding seven days to it. And the result will be your due date.
For instance, if your last period began on May 11th, then counting three months backwards will give you February and adding seven days to it will give you February 18th. The medical term used to describe this is estimated date of delivery or EDD. This is just an estimation provided to you by your doctor.
If you were keeping a track of your ovulation and you have a precise idea about your date of conception then the result will be thirty-eight weeks from that date of conception. An ultrasound exam will help the doctor know the size of the baby which will help in the estimation of a due date.
Studies have shown that just one in every twenty babies is actually born on their due date. The uncertainty keeps the parents guessing about the date of delivery since it could happen anytime between 38 to 42 weeks.

Other Due Date Calculation Methods

  • Changing Due Dates

Other Methods to Check Pregnancy

  • The Size of the Uterus:
    When you are in the twelfth week of your pregnancy then the top of the uterus or fundus will enlarge. After eighteen weeks the distance between the fundus and the pubic bone will be about the same and in twenty weeks the fundus will be as high as your belly button. This method is used to estimate how far along you are in your pregnancy journey, but it is not accurate.
  • Ultrasound Testing:
    If the other alternative methods are proving to be not so fruitful then you may find ultrasound as the best way to opt for. Before reaching the twentieth week of pregnancy, this test is the best way of finding out your gestation period. During the procedure, a small device called transducer is moved all over your belly which sends out sound waves to the attached computer that paints a rough picture of the baby and displays it on the TV.
