The purpose of this study is to see whether women at a gestational age of 30 weeks or more without comorbidities, does performance of serial 3rd trimester growth ultrasounds increase the frequency of identifying abnormalities in fetal growth or amniotic fluid, when compared with women who only receive indicated ultrasounds?

| Primary | Number of Participates With Oligohydraminos | Oligohydramnios is a condition in pregnancy characterized by a deficiency of amniotic fluid. Amniotic fluid was assessed using the amniotic fluid index (AFI) or maximum vertical pocket (MVP). Oligohydramnios was defined as AFI less than or equal to 5.0 cm or MVP less than or equal to 2.0 cm. AFI is the sum of the vertical length of the deepest, unobstructed pocket of amniotic fluid in each of the 4 quadrants of the pregnant uterus. An AFI of less than or equal to 5cm is considered low amniotic fluid, and an AFI greater than or equal to 24cm is considered high amniotic fluid. MVP is the vertical length of the single deepest pocket of amniotic fluid. An MVP less than or equal to 2cm is considered to be low amniotic fluid and an MVP of 8cm or greater is considered to be high amniotic fluid. Both low and high amniotic fluid levels are worse outcomes than having normal amniotic fluid levels. |

| Primary | Number of Participates With Polyhydraminos | Polyhydraminos is a condition in pregnancy characterized by an excess of amniotic fluid. Amniotic fluid was assessed using either the amniotic fluid index (AFI) or maximum vertical pocket (MVP). Polyhydramnios was defined as AFI greater than or equal to 24.0 cm or MVP greater than or equal to 8.0 cm. AFI is the sum of the vertical length of the deepest, unobstructed pocket of amniotic fluid in each of the 4 quadrants of the pregnant uterus. An AFI of less than or equal to 5cm is considered low amniotic fluid, and an AFI greater than or equal to 24cm is considered high amniotic fluid. MVP is the vertical length of the single deepest pocket of amniotic fluid. An MVP less than or equal to 2cm is considered to be low amniotic fluid and an MVP of 8cm or greater is considered to be high amniotic fluid. Both low and high amniotic fluid levels are worse outcomes than having normal amniotic fluid levels. |

| Secondary | Number of Participants With Composite Neonatal Morbidity | Composite Neonatal Morbidity is defined as the presence of one or more of the following: 1) Apgar score < 5 at 5 min; 2) umbilical arterial pH < 7.00; 3) intraventricular hemorrhage grade III or IV; 4) periventricular leukomalacia; 5) intubation for over 24 hrs; 6) necrotizing enterocolitis grade 2 or 3; 7) stillbirth; or 8) death within 28 days of birth. | From time of delivery to 28 days after delivery | |
| Secondary | Number of Participants With Composite Maternal Morbidity | Composite Maternal Morbidity is defined as the presence of one of more of the following: 1) chorioamnionitis; 2) cesarean delivery in labor; 3) wound infection; 4) transfusion; 5) deep venous thrombus or pulmonary embolism; 6) admission to intensive care unit; 7) postpartum hemorrhage; or 8) death. | From time of delivery to discharge (average time of discharge is 4 days after delivery) |
