When will my baby be born?
Determining your due date can seem like a maze these days. How do you
do it and what does it all mean?
Let's take a look at the history of determining due dates and how it
affects when your baby will be born.
It is believed the average length of human gestation is approximately
266 days from conception. Assuming the average woman has cycles that
lasted 28 days and that she ovulates on Day 14 of her cycle. Based on this
here is the data to come up with a mathematical calculation for due dates:
((LMP + 7 days) - 3 months) = Due Date
However, this method does not consider certain factors in the
calculation. For example: Not every woman ovulates on Day 14. Other
situations that do not factor in are ethnicity, parity (how many
successful pregnancies), prenatal care, better nutrition, and screening
factors.
Today we still use the rule above to determine due dates. However,
there is a new rise to the discussion of the accuracy of these
calculations. With the advent of true prenatal care, midwives and
physicians are helping women educate themselves about risk factors,
nutrition and prenatal screening. This extends the lengths of gestation
for many women.
One study indicates that we need to add 15 days to the formulae for
Caucasian, first time mums, and 10 days for Caucasian mums having
subsequent children. African American and Asian women tend to have shorter
gestations.
Nowadays, we use ultrasound, when available or if there is a question
of menstrual history. Ultrasound can be an effective way of dating a
pregnancy, but this accuracy is lost if not performed in the first half of
pregnancy.
Most authorities agree that there are many ways to date a pregnancy,
and that not just one factor should be used to determine the final due
date.
Keep in mind that due dates are estimates of when your baby will
arrive. It is generally consider the normal time frame to be two weeks
before your due date, until two weeks after your due date.
Remember, no matter how many times your neighbours, strangers, mothers,
etc. ask you when you are due, smile, because only the baby really knows. |
