Dating a pregnancy accurately at the earliest possible time is important. In a normal pregnancy it does not matter what the dates are, but if anything should go wrong it becomes very important as to what treatments may be prescribed. Traditionally the last menstrual period has been used to date a pregnancy, but this may be highly inaccurate. A simple formula is to take the first day of the menstrual period, subtract three months and add one week. For instance, if your period starts on the 5th April, then your estimated due date for delivery is the 12th January. The dating scan is an ultrasound scan that can be done as early as six weeks after the last period, but the dating scan will be most accurate when done between 8 and 12 weeks gestation. At this time, the fetus is a little larger and easier to measure. Even dating scans can be inaccurate for the due date, but they are never as inaccurate as using the menstrual period. For instance a dating scan done at 6 weeks could get the date wrong five days either way. A scan at 12 weeks could get the date wrong seven days either way and a scan done at 20 weeks could get the date wrong up to ten days either way.

Ultrasound is a safe and widely used imaging technique. Ultrasound produces detailed pictures of the body in real-time using high frequency sound waves, which are produced by a special ultrasound probe, called a transducer. The frequency of these sound waves is higher than that detected by the human ear and when they are reflected by a part of the body they are detected by the probe and used to create images that can be displayed on a monitor. Because they are captured in real time they appear as moving images not as static or still ones, thus enhancing the diagnostic capability of the test.
Ultrasound has no known harmful effects and can be used to image a variety of conditions including pregnancy, gallstones and varicose veins. Ultrasound can also be used to measure blood flow through vessels, when it is called a colour flow Doppler or Duplex scan. Pregnancy ultrasounds may be performed by examination of the abdomen called transabdominal or by using a special probe designed to be inserted into the vagina, called transvaginal.
The type of examination you will need will depend on what your referring doctor has requested and the nature of the clinical condition being investigated. Your examination or scan will be performed by either a Radiologist a highly trained specialist doctor or a sonographer a specially trained technologist. Because the examiner is interpreting moving images on a screen a high degree of concentration is required to obtain accurate information. Therefore, in most circumstances except obstetric scans, family and friends of the patient are not generally permitted to watch the procedure.
If you have accompanying children you will have to bring along someone to watch them during your examination. Drink glasses of water before your appointment.

At Your Baby Scan, we take our staff and customer’s safety incredibly seriously. As a result, as we re-open our scan centres, we have to make some significant changes to the services we offer and the way we offer them. This page outlines those changes, and how we are keeping you safe, and some instructions you will need to follow when visiting our scan centres. Read on to understand the reasons for each of these and what they mean for you when you come to us for your scan.
As part of our plans for re-opening, we have completed a thorough risk assessment examining every touchpoint within the scan centre and how we can practically protect you. We have also considered various PPE methods for staff and customers, and whilst we are aware some other scan centres have implemented some of these, some we saw no value from in reality and will not be implementing in our scan centres, we have included these considerations in our risk assessment and an evaluation of whether this would improve safety or not.
As the weeks go by, and we test how effective and practical our measures are, or Government restrictions are relaxed, we will be updating this document and making it available to you. Before visiting any other Ultrasound Clinics from companies offering similar services, or with a similar name, you should always ask to see a copy of their COVID Risk Assessment to help you decide whether the environment is safe enough for you, your baby and your family. As part of our COVID risk assessment, we felt that some of our current scan packages were too high risk for both our staff and customers at this point in time.
Specifically, we felt that we should space our appointments out so that we only have 2 appointments per hour, only 1 set of customers should be in the scan centre at any time where possible, and that these appointments should be for essential purposes. We will therefore only offer our Standard package for the interim period. The features of the standard package will remain unchanged, but we will be spacing appointments out, to 30 minutes apart.

Things to know
Your health care provider may request that you have one or more fetal ultrasound scans during your pregnancy. These ultrasound scans provide important medical information that will help you and your health care provider create the best care plan for you and your baby.

It uses sound waves to make a live picture of your baby in the womb that can be seen on a monitor.
