Ultrasounds and dating pregnancy
**The Pregnancy Resource Center offers free ultrasounds to determine how far along you are in your pregnancy and to see if your pregnancy is viable.Our ultrasounds are performed by licensed ultrasound technicians under the direction of obstetricians.With today's modern equipment, we can obtain very reliable images and measurements of even very early pregnancies, sometimes even seeing a heartbeat as early as 5-6 weeks!
The accurate determination of a patient's "due" date, referred to by doctors and midwives as the EDC (Estimated Date of Confinement) or EDD (Estimated Date of Delivery), is very important for a variety of reasons.
The timing of certain tests, the monitoring of the baby's growth, and the correct diagnosis of premature labor, or being truly "overdue," (postdates), as well as many other situations that arise in the course of a typical pregnancy, all depend on a correct determination of the EDC for appropriate management.
In the past, the EDC was calculated by using Naegele's Rule, which determined the date by subtracting 3 months from the 1st day of the last period and then adding 7 days.
Due dates based on high-tech ultrasounds will help doctors in deciding things like when to induce or to administer steroids or other drugs in at-risk pregnancies.
An ultrasound can help you determine how far along you are in your pregnancy.
