Fetal Health and Development

A normal pregnancy lasts nine months. Each three-month period of pregnancy is called a trimester. During each trimester, the fetus grows and develops. There are specific prenatal tests to monitor both the mother's health and fetal health during each trimester.

With modern technology, health professionals can

  • Detect birth defects
  • Identify problems that may affect childbirth
  • Correct some kinds of fetal problems before the baby is born

  • Fetal development
  • Intrauterine growth restriction
