That initial glimpse at your baby-to-be is unforgettable. Getting that initial glimpse of your baby on an ultrasound machine is one of the most exciting moments of pregnancy. Yet many parents-to-be are filled with questions about the first pregnancy ultrasound: When should I get the exam? Will it hurt? What are doctors looking for?
A first trimester early pregnancy and dating ultrasound is an examination you have during the first 13 weeks of pregnancy. Due to the size of the developing structures and embryo, it is uncommon to perform an ultrasound before 5 weeks gestation 5 weeks after the start of your last menstrual period. Ultrasound is not consistently able to confirm viability and fetal heart activity prior to 6 weeks gestation, so unless there is an urgent need to have an early pregnancy and dating scan earlier most of these ultrasounds are performed after 6 weeks and ideally at 8 weeks for dating purposes. Urgent cases may still be performed earlier, please discuss this with your referring doctor. Your ultrasound may be performed transabdominally or transvaginally.
Every pregnant woman wants to know her due date , and a due date that is calculated from her last menstrual period with a due date calculator often doesn't match the due date that is estimated by her first ultrasound also known as a sonogram. During an ultrasound, a technician will spread a warm gel over the lower part of your abdomen and then press a tool called a transducer against your belly to examine your fetus using sound waves. An image of your fetus will appear on an accompanying computer screen and while looking at this image, the technician will take some standard measurements from different angles and listen for a heartbeat. Don't worry: This type of exam is painless and risk-free, and seeing your baby for the first time will likely be an enjoyable experience. Naturally, one of the most common questions asked about ultrasound accuracy is: Just how accurate are the due dates that are predicted by an ultrasound? Evidence suggests that, in the first 20 weeks of pregnancy , the first ultrasound may be the most accurate tool for predicting when your baby will be born. Early ultrasound due dates have a margin of error of roughly 1. If you can't remember your last menstrual period date or if you have consistently irregular cycles, the doctor can use an early ultrasound to give you a fairly reliable due date. If your first ultrasound gives you a due date that is more than 1.

Obstetric ultrasounds are performed in the 1 st trimester for a variety of reasons, including confirmation of the pregnancy and the number of babies, assessment of bleeding, determining the gestational age and well being. You will be required to drink ml of water one hour prior to your examination. This allows the bladder to fill and helps to visualize the uterus, baby and other structures of the pelvis. Hence, do not go to the toilet once you have commenced drinking the water. If you feel as though you may struggle to hold onto the water, you can come to Sound Radiology prior to your scan to drink the water here.
Back to Your pregnancy and baby guide. All pregnant women in England are offered an ultrasound scan at around 8 to 14 weeks of pregnancy. This is called the dating scan. It's used to see how far along in your pregnancy you are and check your baby's development. Your midwife or doctor will book you a dating scan appointment. It will usually take place at your local hospital ultrasound department. The person performing the scan is called a sonographer. You may need to have a full bladder for this scan, as this makes the ultrasound image clearer.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.
