> At Week 39, your baby is considered full term, continuing to fine-tune vital systems as you approach your estimated due date with anticipation and readiness.

Welcome to Week 39, a time often marked by a mix of anticipation and readiness. Your baby is now considered full term, a significant milestone! It's an incredible feeling to be so close to meeting your little one, and this week brings its own unique set of physical and emotional experiences.

## What's happening with baby

At 39 weeks, your baby is roughly the size of a watermelon, feeling quite snug in your womb. While they are fully developed and ready for the world, some crucial final touches are still underway. The brain continues its rapid development, and lung surfactant production is peaking, which is vital for their first breaths. Your baby is also continuing to lay down fat reserves, which will help them regulate their body temperature after birth. Their immune system is also getting a final boost from your antibodies, preparing them for life outside.

## What you might be feeling

This week can be a true test of patience. You might be experiencing more intense Braxton Hicks contractions, which can feel like your uterus is tightening and releasing, sometimes quite strongly. Increased pressure in your pelvis is common as your baby settles deeper. Many parents-to-be also feel a strong nesting instinct, a sudden urge to clean, organize, and prepare the home. Sleep might be elusive due to discomfort or an active mind, but rest is still incredibly important. Emotionally, you might swing between excitement, impatience, and a sense of calm readiness. All of these feelings are a natural part of this final waiting period.

## A doula's lived take

As a doula, I've seen firsthand the unique energy of Week 39. There's often a palpable sense of "is it today?" or "when will it happen?" It's a beautiful time to lean into trust – trust in your body, trust in your baby, and trust in the process. One option might be to shift your focus from "waiting for labor" to "preparing for birth." This could involve gentle movement, listening to calming music, or spending quiet moments connecting with your partner. Remember, your body knows what to do, and your baby is preparing too. Every day spent inside is a gift, allowing for those final, important developments. This is a time for gentle self-care and quiet confidence, knowing that your personal timeline is just right for you and your baby.

## Questions worth asking your provider

As you approach your estimated due date, it’s always valuable to stay connected with your care team. Some questions you might consider asking your OB or midwife this week include:
- What are the signs that I should call you about?
- What are my options if I go past my estimated due date?
- Can we review my birth preferences one more time?
- What is your typical protocol for [specific scenario, e.g., ruptured membranes without contractions]?
Your provider is your best resource for your specific situation, and having these conversations can help you feel even more clear and confident as you await your baby's arrival.
