39th Week

A Little Star Getting Ready to Shine

Welcome To Week 39!

You are right at the finish line and ready to give birth at any moment. Your body works overtime prepping the birth canal as the baby’s head moves deep into the pelvis, commonly triggering intense pelvic pressure, pre-labor nausea, or the opening “show” discharge. 

  • Your baby is fully positioned for birth and now weighs over 3 kg, measuring approximately 50.1cm from head to toe. 
  • A critical layer of fat has fully developed under the skin to safely regulate body temperature after birth.
  • Fetal boys may typically be slightly heavier than girls at this final stage of full-term development.
  • Real labor contractions are distinct because they become progressively painful, frequent, and do not fade with rest.
  • Baby is about the size of a mini watermelon.
