A test to check on how the baby is doing while inside the uterus. Using ultrasound, this test assesses fetal breathing, fetal movement, fetal tone, and amniotic fluid volume.

Irregular or "practice" contractions starting around the eighth month that prepare your uterus for labour. Unlike true labour, Braxton Hicks contractions aren't painful and don't get stronger and closer over time.
