40 Weeks Pregnant
Due date! Baby is ready to meet you.
🧒 Baby's Development This Week
Your baby is officially full-term and ready to meet the world! About the size of a small pumpkin, they have shed most of their lanugo and vernix. Their lungs are mature and ready for their first breath, and their liver has stored enough starch to turn into glucose after birth. They are likely nestled deep in your pelvis, waiting for the signal that it's time to begin their journey.
- Major organ systems are forming.

🤰 Your Symptoms at Week 40
The anticipation is at an all-time high this week. You're likely feeling very heavy and ready to be done, with symptoms like pelvic pressure and frequent 'lightening' as the baby drops lower. Remember that only about 5% of babies arrive on their actual due date, so don't be discouraged if you go a few days past 40 weeks—your baby is just getting those final, finishing touches!
