Your Very First Pregnancy Scan

You can take your first ultrasound scan as soon as you suspect that you’re pregnant due to a pregnancy home test. This can be as early as four weeks, yet an internal transvaginal probe may be used before 7-8 weeks. The main reason for taking this first scan, also called a “viability scan”, “dating scan” or the “early pregnancy scan”, is to confirm your pregnancy – and whether it’s a single pregnancy or a twin pregnancy. The presence of the father is welcome at the first appointment, as mums feel more comfortable with the support of a partner at this very first scan. Here are more things to expect from your first scan:

Calculation of the estimated due date

The estimated due date (EDD) is the approximate date at which you should expect to deliver the baby. The early pregnancy scan is also called a “dating scan” because it estimates your stage of pregnancy and the delivery date. The EDD is calculated based on the date of your last menstrual cycle and other factors like the stage of the pregnancy progress observed during your scan appointment.

Checking for single or twin pregnancy

After the embryo has formed, the sonographer will be able to see if, well, two embryos have formed. Identical twins are at first formed from a single embryo that later divides, so it is possible that one twin may be missed at your first scan, especially if you carry out the scan earlier than 6 weeks.

A scan report

Notes are recorded on a written report during the first ultrasound scan. You can take this report with you at the end of the scan. Keep it for future references at doctor appointments and later pregnancy scans.

Ultrasound images of your baby

At Baby Scan Clinic, we offer two glossy images on the day of the scan, for you to take away. These images make a great addition to a baby album.

How to prepare for the early pregnancy scan

Eat and drink as normal on the day of your appointment and wear lose clothing if possible. Ultrasound images are clearer with a full bladder, which is why we recommend to drink a pint of water in the hour leading to your scan appointment without emptying your bladder.
