So, you have reason to believe you're expecting. Congratulations!
It is really a wonderful thing. Of course, if this is your first time
you're probably a little frightened. Don't worry about it. This is a
normal part of the deal. Wait until the hormone changes start taking
place, then you'll feel ups and downs like never before!
That's all right, too. We'll allow you to have emotional ups and downs. After all, you're being moody for two now. Anyway, let's take care of the business at hand, namely figuring out exactly when the stork is going to show up at your doorstep with the most beautiful package you've ever seen!
40 Weeks
First, exactly how long is a human pregnancy? The answer is 40 weeks from the first missed menstrual cycle. To put it another way, a pregnancy lasts 280 days. This is true simply because 7 days times 40 weeks equals 280 days.
What's so unique about the 280 day or 40 week thing is that if every month were like a non-leap year February, that is 28 days, we'd all be talking about the 10 month pregnancy instead of the ever popular wives tale version which says pregnancies last 9 months. On average, on a real calendar 280 days is 9 months and 10 days. Let's talk a little bit more about this 10 month thing.
Is It 9 Months or 10!
Even though it is becoming more and more accepted pregnancy begins at conception, the count down to delivery starts at the first missed menstrual cycle. This is because this is the way the human body works. At least, it is the way a female human body works.
In other words, it takes these no longer outwardly apparent menstrual cycles to help the baby grow inside until he or she is ready for birth. This usually happens at around the tenth 28-day period after the first missed cycle. In actuality, though the delivery can expect to happen 9 months and 10 days after the first missed menstrual cycle, conception could have happened 3 weeks before. So, there is your 10 months! So much for the long ballyhooed 9 month pregnancy!
The Middle of the Menstrual Cycle
Anyway, when calculating the due date, try to figure out when the middle of the first missed menstrual cycle would have been. This won't guarantee 100% accuracy but on average it will give you the best estimate which is the best any due date calculation can do.
Let's try an example. The middle of the first missed menstrual cycle is August 12, 2008. Adding 9 months and 10 days to this date gets us to May 22, 2009. Interestingly, referring to the top ranked due date calculator, the due date is said to to be May 18, 2009.
Why is there a difference? Well because all months aren't 30 days long and there are some months between August and May that are 31 days. So, to be more accurate, you have to take these things into consideration.
Still, predicting when babies, or trains or packages in the mail will arrive is not an exact science. The bottom line is, due date calculations are nothing more than educated guesses, but they are fun to make none the less.
