Our due date calculator is simple to use and gives you a good idea of when to expect your baby. Remember, a “due date” doesn't tell you exactly what day your baby will arrive. It's better to think of it as a loose estimate.
It's generally considered “safe” for your baby to come when you are between 37 and 42 weeks pregnant. This gives a five week range to look for your baby's birthday! With a healthy pregnancy you'll probably carry your baby to 40 weeks, and first time mothers are especially likely to go over their due date. Babies born at 39, 40, and 41 weeks are usually the healthiest – there is a lot of brain and bone development that occurs between 36 and 40 weeks.
Some women like to say a general rather than a specific date. For instance they say “I'm due in late August” instead of “August 25th.” You can even say your due date is a month later than it truly is! This may seem strange, but it won't when you're close to your due date and everyone keeps saying “you haven't had that baby yet?!”
Just remember, your due date is an estimate and not set in stone. Expect your baby will be born sometime around his or her due date but probably not on it![raw]
The Due Date Calculator gives you good estimates of three dates. Date of conception is the date that your baby was probably conceived. This date is approximately two weeks after your last menstrual period. Due Date is the approximate date for when your baby will make his or her arrival. Remember this is just an estimate. Estimated fetal age tells you about many weeks of development your baby has reached.
