What’s The Value of A Pregnancy Calculator?
There are several ways to calculate pregnancy due date. One is to use an online pregnancy calculator. With an online pregnancy calculator, you enter the enter on the screen the first day of your last menstrual period, then click the button. The computer will do the work for you….
But you don’t have to use a pregnancy date calculator to determine when your baby is due. You can easily do it yourself, using the same information (first day of your last period) and looking on a calendar. If you add 40 weeks (or 280 days) to that date, you will get to the approximate date your baby will be born.
