This program helps you plan for the important milestones in your pregnancy. Choose the date of your last period and the dates will change accordingly. The following details will be displayed instantly: the probable date of conception; the start date of the second and third trimesters; the date that most babies will survive; the dates that most babies may arrive between; the number of weeks and days you are pregnant; the number of weeks and days you have left until the special day; the date the baby is expected and finally what star sign it will be born under. You can also print out the results with the mother's name if you wish. If you want the birth on a certain day, the calculator can also let you know what date the approximate conception should be. More information is given by clicking on the Help button about conception, whether it's a boy or girl, the embryo and the second and third trimesters.Version 2.72 may include unspecified updates, enhancements, or bug fixes.
