Experimenteel: Serial third trimester ultrasound
Ultrasound evaluation for fetal growth and amniotic fluid will be performed every 4 weeks starting at 30 weeks (intervention group).
Thus, if they continue to term, there will be 3 additional ultrasounds exams (30, 34 and 38 weeks).

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. |

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. |
