Due Date Calculator Congratulations, you're pregnant! So when is
the baby due? Calculate your expected due date using Essential
Baby's Due Date Calculator. How is my due date calculated? The
start of your pregnancy is actually calculated from the start
date of your last menstrual period (LMP), or day 1 of your
cycle. Given this method of calculation, your pregnancy is
measured in what is termed gestational weeks, as opposed to
being measured from the actual day of conception. Counting from
the first day of your LMP, there are 40 gestational weeks of
pregnancy. Assuming that you have a 28-day cycle, in gestational
weeks 1 and 2, your baby is waiting to be conceived. On day 14,
and at the start of gestational week 3, your baby has just been
created. By the end of gestational week 3, the actual age of
your baby is one week. Please remember that your baby will come
when it is ready, so this result is an estimate only. Be sure to
consult your healthcare provider to determine your correct due
date. Find more inform
