37 Weeks Pregnant: What to Expect in the Final Stretch

You’re officially in the home stretch of your pregnancy—congratulations! At 37 weeks, you’ve reached early-term pregnancy, and your baby could arrive any day. Let’s explore what’s happening with your body, your baby, and how to prepare for labor.

Your Baby at 37 Weeks

At 37 weeks, your baby is preparing for their big debut!

• Size and Development: Your baby is about the size of a Swiss chard, weighing 6–6.5 pounds and measuring around 19 inches long. Most of their organs, like the lungs and brain, are developed, but the brain continues to grow rapidly.
• Positioning: Most babies have moved into a head-down position by now, preparing for delivery.
• Appearance: Their skin is smooth, and they’re building fat, which helps regulate body temperature after birth.

Did you know? Babies born at 37 weeks typically do very well outside the womb, though they may still be considered early-term and need a bit more time for optimal development.

Changes in Your Body

Your body is also getting ready for labor, with noticeable symptoms and sensations:

• Braxton Hicks Contractions: You might feel irregular, mild contractions as your uterus practices for labor.
• Increased Pelvic Pressure: As your baby drops lower into the pelvis (lightening), you may feel more pressure in your lower abdomen.
• Discharge Changes: You might notice an increase in discharge, possibly tinged with blood—this could be your mucus plug, signaling labor is approaching.
• Fatigue and Nesting: While you might feel tired from carrying the extra weight, bursts of energy (the "nesting instinct") could inspire you to prepare your home for your baby.

Tip: Stay hydrated and rest often to manage discomfort during these final weeks.

Preparing for Labor

With delivery just around the corner, it’s time to focus on preparation:

• Pack Your Hospital Bag: Include essentials for you, your baby, and your partner, such as clothes, toiletries, snacks, and important documents.
• Finalize Your Birth Plan: Discuss your preferences with your provider, including pain management, delivery options, and immediate postpartum care.
• Install the Car Seat: Ensure it’s securely installed and meets safety standards.
• Watch for Labor Signs: Common signs include:
• Regular, stronger contractions.
• Water breaking (fluid leakage).
• Lower back pain or cramping that doesn’t go away.

Pro Tip: Call your healthcare provider if you’re unsure whether labor has started or if you notice any unusual symptoms like heavy bleeding or reduced baby movement.
Common Questions at 37 Weeks
Q: Should I be worried if my baby hasn’t dropped yet?
Not necessarily! Some babies don’t drop until labor begins. Your provider can monitor your baby’s position at your next checkup.
Q: Can I still exercise?
Light activities like walking or prenatal yoga are great, but always listen to your body and avoid strenuous exercises.
Q: When should I go to the hospital?
If your contractions are about 5 minutes apart and last 60 seconds for an hour (5-1-1 rule), or if your water breaks, it’s time to head in.

Celebrate Your Progress

You’ve made it so far! This week is an excellent time to cherish these final days before your baby arrives. Whether it’s a quiet moment of self-care or a fun date night, remember to honor yourself for all the hard work you’ve done.
