Due Date Calculator

It is every woman’s joy to become pregnant (at the right time), to finally start the family you have been wishing for since you were a young girl. But now that you are pregnant, you cannot help yourself wonder when the baby will arrive. This article will discuss how to use a due date calculator to find out when to expect your little bundle of joy.

There are several methods the calculator uses to give you an estimated due date. They include:

Last menstrual period method

The calculators that use this method, add 280 days to the first day of your last menstrual period. The due date however is considered an estimate because for the 280 days added, 14 days are assumed to be from when you started your menstrual cycle till when you ovulated.

Naegele’s Rule

This method is normally used by doctors when you go in for your check up. The doctor will ask for the first day of your last menstrual period. From this he/she will count back three months from this date and add seven days. The assumptions in this method is that your cycle occurs after every 28 days and ovulation is on the 14th day.

Basal Body Temperature

This is the temperature you measure every morning prior to even getting out of bed. This baseline temperature increases slightly during ovulation. So if you add 266 days to the day of ovulation, you will end up with your due date.

There are numerous online due date calculators. So just type due date calculator on your search engine and have a go at it or you can check any website and their due date calculator . It is however important to note that the due dates given are merely estimates. And that few women actually give birth on said date. This is because of the assumptions made. The due dates however help you be best prepared for birth. If you have an irregular cycle your doctor can calculate a due date for you.
