Baby's Growth and Development at 19 Weeks Pregnant

During the weeks before, during, and after your 19th week of pregnancy, your baby’s brain develops at a phenomenal rate. Other systems continue to grow.

  • Your baby now measures about 15.20 cm, or the length of a baby marrow.
  • When you’re 19 weeks pregnant, your baby’s brain develops millions of motor neurons. Neurons are nerves that help muscles in the brain communicate. This new and ongoing development means your baby can make purposeful and involuntary movements. They can suck their thumb, move their head, or make other moves that you might start to feel.
  • Your baby’s hearing is even more developed when you’re 19 weeks pregnant. They can probably hear external sounds and conversation by this time, or will very soon. Your voice is the most pronounced. Your baby can hear you talk, hum, and sing!
  • Your baby’s skin is covered in a white, waxy, protective coating called vernix.
  • Under the vernix, the fine hair called lanugo continues to cover her skin.
  • By your 19th week of pregnancy, your baby’s kidneys begin to function. Their urine is excreted into your amniotic sac, the bag of fluid in your uterus that contains your baby and amniotic fluid. Your placenta then removes the waste.

Your Changing Body at 19 Weeks Pregnant

During your 19th week of pregnancy and the weeks surrounding this time, your body continues to change and adapt to accommodate your baby’s current growth and future needs.

  • Your body makes more blood.
  • Your circulatory system expands and keeps blood pressure lower than normal. As a result, you might get dizzy, lightheaded, nauseated, or faint if you stand or rise too quickly.
  • At 19 weeks pregnant, your lung capacity continues to increase. You might breathe faster or experience shortness of breath.
  • Your breast cup size increases around your 19th week of pregnancy due to enlarging milk-duct glands and increasing blood flow.
