What
Do You Mean You
Don't DO DUE DATES????
That's
right folks - we don't give due dates...due dates are estimates of when
your baby will arrive. Natural Attachment does
not generally give you a due date. We consider the usual time
frame to be 38 to 42 weeks (36 - 46 weeks are not unusual) from
the day of conception, therefore, we will give you a due
month.
But,
if you're incredibly structured, we have a little cheat sheet to help
figure out how long you have until the big day (keep in mind that
babies come when THEY are ready)...
Most
people are used to being assigned a EDD. Your expected
delivery date (EDD) is 40 weeks from the first day of your last
menstrual period
(LMP). If you birth on your EDD, your baby is actually only 38 weeks
old - that's because your menstrual period and ovulation are counted as
the first 2 weeks of pregnancy. It's
important to remember
that your due date is only an estimate - most babies are born between
38 and 42 weeks and only a small percentage of women actually birth on
their due date (that's why we give you a Due Month).
A little history on this subject:
Dr.
Naegele, circa 1850, determined that the average length of human
gestation was approximately 266 days from conception. He assumed that
the average woman had cycles that lasted 28 days and that she ovulated
on Day 14 of her cycle. However,
we know that this isn't true!!
He
used his data to come up with a mathematical calculation for due dates:
((LMP + 7
days) - 3 months) = Due Date
EX: ((January 1, 1996 + 7 days) - 3 months) = October 8, 1996
However,
Dr. Naegele did not consider certain factors in his calculation. For
example: Not every woman ovulates on Day 14.
One
study indicates that we need to add 12 days to the Naegele EDD for
Caucasian, first time moms, and 7 days for Caucasian moms having
subsequent children. African American and Asian women tend to have
shorter gestations.
Nowadays,
doctors 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. Not to mention the current controversy as to whether or
nor ultrasounds are actually safe for the unborn child. Natural
Attachment does not offer or perform ultrasounds and advises against
Vanity Ultrasounds (Keepsake Ultrasounds and ultrasounds used to
determine the child’s sex).
Most
folks 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. Other
factors to consider are:
- Quickening (first time
mom feels the baby move)
- Fetal heart tones heard
through doppler, stethoscope and fetoscope
- Fundal height
(Measurement of the uterus done throughout pregnancy)
- A mother's Fertility
