Pregnancy Calculator

To understand how the calculator works, follow the instructions below.

First, write down the last date of your menstrual period and your menstrual cycle's number of days on the lines of the calculator and turn it on.

Second, if necessary use the optional calculations to know precisely at which pregnancy stage you are. According to Women's Health magazine, a menstrual cycle includes on average 28 days; however, in some cases, it can be as little as 22 days or even long as 44 days.

Our innovative Pregnancy Calculator takes your menstrual cycle into consideration when calculating your conception or due date. You will need to enter the number of days in your menstrual cycle to get accurate results. If you have forgotten to make calculations on your own because of work or other activities, the Pregnancy Calculator seems to be a perfect assistant for you.
