Baby's Growth and Development at 12 Weeks Pregnant

From the tiny details to major developments, your baby's growth continues with significant progress during your 12th week of pregnancy:

  • When you're 12 weeks pregnant, your baby is almost 3 inches long. That's about the length of a plum.
  • When you’re 12 weeks pregnant, your baby's facial features continue to become more defined, particularly his nose and chin..
  • Tiny fingernails and toenails arrive for your baby when you're 12 weeks pregnant.
  • Your baby's heart might even speed up by a few beats per minute..
  • By the 12th week of your pregnancy, your doctor might be able to hear your baby's heartbeat for the first time, using a special Doppler device. You can ask about this at your next prenatal visit..
