Baby's Growth and Development at 13 Weeks Pregnant

By your 13th week of pregnancy, your baby's organs, nerves, and muscles have formed and are beginning to work together. It's time to focus on growth!

Ultrasounds can capture your baby's early movements as early as the 8th week of your pregnancy!
  • This week, your baby is about the length of a plum.
  • Eyes and ears are clearly defined. Your baby's eyelids are fused together to protect her still-developing eyes.
  • Tissue, which will harden into bone, is developing in your baby's head, arms, and legs. Tiny ribs might be visible.
  • She's already on the move! Your baby might be moving her body in jerky motions as she flexes her arms and kicks her legs, but you won't feel her move for at least several more weeks.
  • Vocal chords develop.
  • Your baby's circulatory system helps clear toxins from her body.
  • When you're 13 weeks pregnant, your baby's head probably is about half the size of her body.
