YES! Yes! Yes! You need to drink plenty of water 4-5 days leading up to your appointment (unless you’re on a fluid restriction). About 64 oz. of water a day. This will help get clearer images since hydration help ensure your amniotic fluid levels are optimal for the best scan results. Drinking water the morning of your ultrasound will not help at all. Please drink the water as instructed for the best 3D/4D pictures. Book an appointment for a 3D or 4D ultrasound in Chicago at Baby Bound Ultrasound!
