The ultrasound technician takes specific measurements of your baby.These measurements help them determine how far along you are and help to estimate a due date.Your ultrasound appointment will probably be the standard where you're asked to drink a lot of water and the technician squeezes gel on your abdomen and uses a probe to "look" at your baby.
A specially designed probe is used inside the vagina.
Because the probe is already close to your baby bean, you won't be asked to fill up on water before the appointment.
That's a plus considering the increased visits to the bathroom.
by Shannon Bartlett You've been in for your first prenatal visit and had your pregnancy confirmed.
If your cycles are irregular or you're not sure when your last period was, your next appointment might be an ultrasound to date your pregnancy.
The ultrasound can be done at a separate facility or right in your doctor's office.
Don't forget to ask for a copy of your "baby's first picture!
" It makes a great memento for your digital or paper scrapbook. Ultrasound dating is most accurate early in your pregnancy.
Your midwife or doctor might have included the scan as part of that extensive first visit.
When performed at seven to 11 weeks gestation, a dating ultrasound can pinpoint your conception date to within three to five days.
It's still fairly accurate up to end of the first trimester.
