Pregnancy ultrasounds are a safe and non-invasive way for expecting parents to get a glimpse of their little one before birth. They use high-frequency sound waves to produce images of the fetus and the uterus.

There are different types of pregnancy ultrasounds, including:

1. Transvaginal ultrasound: This type of ultrasound uses a small wand that is inserted into the vagina to produce images of the uterus and early pregnancy. It can be used to confirm pregnancy and determine the due date.

2. Transabdominal ultrasound: This type of ultrasound uses a wand that is placed on the abdomen to produce images of the uterus and baby. It can be used to detect multiple pregnancies, evaluate the baby’s growth and development, and detect potential problems such as birth defects or placental problems.

3. Doppler ultrasound: This type of ultrasound uses sound waves to evaluate the blood flow in the baby’s blood vessels. It can be used to detect potential problems with the baby’s heart or blood vessels.

4. 3D and 4D ultrasound: These types of ultrasound produce detailed images of the baby’s face and body, allowing parents to get a better view of their baby’s features before birth.
