Though this software lacks zeal, it is capable of calculating pertinent dates for conception and during pregnancy. Simply insert the first day of your last menstrual period and Pregnancy Calculator's colorful interface immediately computes a probable conception date, the start of your second and third trimesters, and your expected due date. We particularly like the best chance of survival date given in case of premature birth. Pregnancy Calculator's help file is its best feature because it offers conception facts, as well as growth and development information during each trimester. While its features are readily available on the Web, mommies- and daddies-to-be will appreciate the opportunity this free application provides to analyze pregnancy data in one sweep.
