Pregnant women can use the pregnancy calculator on the BabyCenter website to figure out which week of pregnancy they are currently in. Once the week of pregnancy is determined, visitors can find information about their pregnancies week by week.

In order to use the pregnancy due date calculator on BabyCenter, a mother-to-be has two options. She may enter the first day of her last menstrual period. This is the method that is used by most doctors to determine a baby's due date. Inversely, a woman may enter the date that she conceived the child. This last option is a tricky one, as it is very hard to pinpoint this day in many instances. Once the date is entered, the visitor clicks on the link labeled "Calculate My Due Date" to determine when the baby is due.
