We
will perform a sonogram to determine the
length of your pregnancy. A sonogram is
a test which uses sound waves to see the
pelvic structures. It is not an X-ray and
there is no radiation. A sonogram is done
while you lie down and a gel solution is
applied to your abdomen. There is little
or no discomfort while the sonogram is being
performed.
A sonogram is considered the most
reliable method of assessing the length of pregnancy.
Although you may have had a sonogram elsewhere
before coming to our office, we must perform our
own sonogram.
The length of pregnancy is based
from your last menstrual period and not from the
date of conception. Therefore, if you think you
conceived 8 weeks ago, your last menstrual period
was probably 10 weeks ago and you would be considered
10 weeks pregnant.
