What is a pregnancy calculator?

A pregnancy calculator can be either an online or manual tool. It is primarily used to determine the pregnancy week range or due date. The calculation involves counting from the last period to the expected day of baby delivery. While the calculation may vary because babies can be delivered before the due date, in most cases, the baby is expected to be delivered around 40 weeks, as indicated by the general concept displayed by the pregnancy calculator. This tool also allows for the calculation of weekly baby growth or activity in the mother’s womb.

How to calculate the pregnancy due date using an online pregnancy calculator?

You can calculate the pregnancy due date either manually or by using an online pregnancy calculator. Doctors typically calculate the due date based on the pregnancy calendar or ovulation tests, resulting in a high level of accuracy. However, you can also use an online pregnancy calculator to estimate your due date. To do this, you’ll need to know your last period date and perform a pregnancy test to determine whether it is positive or negative, which will aid in the calculation of the due date.

What is the method for calculating the pregnancy due date?

  • Our online pregnancy calculator is designed based on general pregnancy concepts. To use the calculator, follow these steps:
  • Select an option from the dropdown menu (due date, last period, ultrasound, conception date, or IVF transfer date) according to the calculation you want to perform.
  • Select the full date format (dd/yy/mm) based on the first selected option.
  • Choose the average length of your menstrual cycle (this option may not be applicable in some cases).
  • Select embryo age (this option may not be applicable in some cases).
  • Click the calculate button.

Below the calculate button, the results will be displayed in a table, showing your week, start date, end date, estimated delivery time, and milestones.
