An ultrasound creates pictures of the baby. This test is usually completed around 18–20 weeks of pregnancy. The ultrasound is used to check the size of the baby and looks for birth defects or other problems with the baby.
Fetal ultrasound during pregnancy can also show the possibility of certain birth defects. But ultrasound is not 100% accurate. Some babies with birth defects may look the same on ultrasound as those without problems.
Screening tests for birth defects are blood tests and ultrasounds. The blood tests are used to look for the amount of certain substances in your blood. The doctor uses an ultrasound to look for certain changes in the baby. Diagnostic tests involve taking some of the baby's cells to look at the genes and chromosomes.
About 15 per cent of scans will be done again for one reason or another and most problems that need a repeat scan are not serious. The most common reason is that the sonographer has not seen everything they need to see. This may be because your baby is not in the best position for scanning, or that you are overweight.
A Detailed Anomaly Scan done at 20 weeks can only detect 50% of Down Syndrome cases.

The heart of the baby starts to beat around the fifth week of pregnancy. To confirm the heartbeat of your baby, the doctor may conduct a non-stress test.

First Trimester (0 to 13 Weeks)
The first trimester is the most crucial to your baby's development. During this period, your baby's body structure and organ systems develop. Most miscarriages and birth defects occur during this period. Your body also undergoes major changes during the first trimester.
Most birth defects occur in the first 3 months of pregnancy, when the organs of the baby are forming. This is a very important stage of development. However, some birth defects occur later in pregnancy.
An environmental cause can include drugs, alcohol, or a disease the mother has that can increase the chance for the baby to be born with a birth defect. An agent that can cause a birth defect is known as a teratogen. Multifactorial birth defects are caused by a combination of genes and environmental exposures.
The most common severe congenital disorders are heart defects, neural tube defects and Down syndrome. Although congenital disorders may be the result of one or more genetic, infectious, nutritional or environmental factors, it is often difficult to identify the exact causes.
There are no symptoms of a baby not growing well. Your healthcare professional should be able to tell if there are any issues by measuring your bump during your antenatal appointments. This will show the midwives if there is steady growth, no growth or decline in the growth.
In general, call your baby's doctor if your infant seems especially sluggish, is refusing food or drink, is vomiting (not just spitting-up), has diarrhea, or has a fever. Remember, if you're worried, there's probably a good reason even if you don't recognize it, so don't hesitate to call your baby's doctor.
