In one sentence, describe what the following article is about:

The American Association of Obstetricians and Gynecologists recommends against 3D ultrasounds. Such procedures are not medically necessary. There are currently no known risks, but the technology is fairly new and risks could be discovered in the future.  A 3D ultrasound is meant only to obtain a picture of the baby. Therefore, those conducting exams may miss abnormalities. Conversely, a minor issue with the baby may be misdiagnosed as a major abnormality. This can cause unnecessary stress during a pregnancy. If you choose to have a 3D ultrasound, have a regular ultrasound conducted by your regular OB/GYN as well. You want to make sure you catch any abnormalities with your baby. A 3D ultrasound is not a substitute for proper medical care. As they are not medically necessary, your insurance may not pay for a 3D ultrasound. The ultrasound can be expensive. If you choose to get an ultrasound done, make sure you're prepared for a large bill. Weigh the costs of medical care during pregnancy, as well as the coming costs of childcare and preparing your home for a new baby. Make sure a 3D ultrasound is within your budget. A 3D ultrasound is not usually harmful to a developing fetus. However, talk to your regular OB/GYN before scheduling a 3D ultrasound. You want to make sure your regular doctor thinks the procedure is safe for you and your baby. You also want to make sure you're getting medical ultrasounds throughout your pregnancy to assure your baby is healthy.

Summary:
Familiarize yourself with the setbacks. Prepare for hefty fees. Talk to your OB/GYN before scheduling the ultrasound.
