As you embark on your pregnancy journey, you're probably thinking that your ultrasound test is exciting -- but pretty straightforward. It's just a procedure that most doctors recommend to assess your and your baby's prenatal health, right? Yes, but it can also determine many important factors of a pregnancy: how the baby is developing, how far along your pregnancy is, or if any congenital abnormalities are present. Furthermore, there are a variety of ultrasound tests that you can undergo depending on your personal circumstances, so it's important to know the differences. By arming yourself with the proper knowledge, you'll be ready to make the right decision with your doctor.
