Pregnancy Calculator

In order to understand how the calculator works, please follow the instructions below:

First, input the last date of your menstrual period and the number of days in your menstrual cycle in the appropriate fields of the calculator and turn it on.

Second, if necessary, use the optional calculations to determine precisely at which stage of pregnancy you are. According to Women's Health magazine, a menstrual cycle typically lasts 28 days on average, but in some cases, it can be as short as 22 days or as long as 44 days.

Our innovative Pregnancy Calculator takes your menstrual cycle into account when calculating your conception or due date. You will need to enter the number of days in your menstrual cycle to obtain accurate results. If you have forgotten to do the calculations on your own due to work or other activities, the Pregnancy Calculator can serve as a perfect assistant for you.
