What Does Your Due Date Mean?

What Is A Due Date?

Your due date. It is probably the most important date in all of pregnancy, besides the day that your baby actually arrives, of course. It’s the day that moms to be will look forward to for 40 weeks, the day that marks “the end,” and time to meet your baby!  Claim Your 20 Free Pregnancy Tests – Click Here

But, what does a due date really mean? Basically put, a due date is a guess. That’s it, just a guess, of when your baby will arrive. 40 weeks is the rough estimate of a woman’s pregnancy, but babies born at 37 weeks are considered full term. Some babies come “early,” some babies come “late,” but all babies come whenever they are ready, and we are all at their mercy!

How Is A Due Date Calculated?

There are several things that go into the calculation of a woman’s due date. The date of a woman’s last menstrual cycle is one of the first questions that a pregnant woman will be asked to help determine her due date.

Of course, some women have longer cycles and shorter cycles, which make it harder to calculate properly. The doctor will usually figure on average 40 weeks, or 280 days from a woman’s last menstrual period to calculate her due date.

However, this doesn’t take into consideration the differences in cycle length from woman to woman, the fact that some months have more or less than 30 days, or other discrepancies. Doctors will also look at the size of the fetus to help determine the due date. As you can see, none of these are an exact science, which is why due dates are only an estimate.

What To Remember

When your doctor tells you your due date, don’t get too caught up in it. Remember that due dates are only an estimate, and really should be thought of as a time frame of a week or two before or after in which your baby will arrive. Keep in mind that only five percent of babies are born on their due dates, so they are not reliable indicators of when a pregnancy will be “done”.

Don’t freak out if your baby starts to come before the due date, and don’t lose it if your due date passes and your little one is still snug inside the womb. All babies will arrive when they are good and ready, and the best we can do is just guess when that will be!
