“Your body was built to nurture life—and right now, it’s doing exactly that.”

Welcome to Week 31 of your pregnancy. At this stage, you’re well into your third trimester, and the countdown to meeting your baby feels more real than ever. As your belly continues to grow and your baby prepares for life outside the womb, you may find yourself juggling a whirlwind of physical sensations, emotional highs and lows, and anticipation for the journey ahead.

This week marks a critical phase in your pregnancy where both you and your baby are undergoing rapid developments. From stronger kicks to increased fatigue, understanding what’s happening now will help you feel more prepared and empowered. Let’s explore what Week 31 brings in terms of fetal growth, maternal changes, emotional wellness, and tips for support.

Baby’s Development at Week 31

By Week 31, your baby is about the size of a coconut—roughly 16 inches long and weighing around 3.3 to 3.5 pounds (1.5 to 1.6 kg). From this point forward, your little one will gain about half a pound each week until delivery. That rapid weight gain helps in developing fat layers beneath the skin, which regulate body temperature after birth.

Here’s what else is happening with your baby:

• Lungs are maturing: Though not fully developed, the lungs are producing more surfactant, a substance that helps the lungs expand after birth.
• Brain development is accelerating: Neuronal connections are being formed rapidly, and the brain is starting to look more wrinkled—indicating more surface area for higher cognitive function.
• Movements are stronger: Punches, jabs, and rolls may now be unmistakable and might even take your breath away. Baby is also getting into position for birth—head-down is the ideal.
• Eyes can blink: Your baby can now open and close their eyes, and may even respond to changes in light and sound from outside the womb.

Your Body at 31 Weeks Pregnant

Your body is working tirelessly to support your baby’s growth and prepare for childbirth. Some symptoms from earlier weeks may continue, while new ones might surface. Every pregnancy is different, but here are common physical changes you may notice this week:

• Shortness of breath: As your uterus expands upward, it can press against your diaphragm, making it harder to breathe deeply.
• Frequent urination: The growing baby puts pressure on your bladder, especially if your baby is dropping lower into your pelvis.
• Fatigue and insomnia: Sleep may become challenging due to discomfort, heartburn, or vivid dreams. Using extra pillows for support may help.
• Leaky breasts: You may notice colostrum, the first milk, leaking from your nipples. This is completely normal.
• Swelling: Mild edema in your feet, ankles, or hands is common, but report sudden or severe swelling to your doctor immediately.

Emotional Wellbeing in the Third Trimester

As you approach the final weeks, your emotions may swing between joy, nervousness, and even moments of fear. Hormonal fluctuations are at play, but so is the weight of anticipation and the realization that your life is about to change profoundly.

Here are a few ways to support your mental health at this stage:

• Practice mindfulness: Deep breathing exercises, gentle prenatal yoga, or meditation can help you stay grounded and reduce anxiety.
• Talk it out: Don’t hesitate to share your feelings with your partner, a trusted friend, or a therapist who specializes in perinatal mental health.
• Join a support group: Online or local groups can provide reassurance that you’re not alone in your experiences and concerns.

Tips for a Healthy Pregnancy This Week

Here are some practical and nurturing suggestions for maintaining your wellbeing during Week 31:

• Nutrition matters: Prioritize iron-rich foods like spinach, lentils, and red meat to prevent anemia. Vitamin C can enhance iron absorption.
• Stay hydrated: Aim for 8–10 glasses of water a day to support amniotic fluid levels and reduce swelling.
• Keep moving: Gentle walks and prenatal stretching help maintain circulation and ease body aches.
• Wear comfortable shoes: Your center of gravity has shifted, so supportive footwear is essential for balance and comfort.
• Prepare your hospital bag: Now is a good time to start gathering essentials for you and baby—think comfy clothes, toiletries, and documents.

Partner’s Corner

If you’re supporting a pregnant partner, Week 31 is a great time to step up emotional and physical support. Attend prenatal appointments if possible, offer help with household chores, and ask how they’re feeling—physically and emotionally. This shared experience strengthens the bond between you and helps prepare for life as co-parents.

When to Call Your Doctor

While many discomforts are typical during pregnancy, certain signs should prompt a call to your healthcare provider:

• Severe or sudden swelling in the face, hands, or feet
• Persistent headaches or visual disturbances
• Heavy vaginal bleeding or unusual discharge
• Decreased fetal movement
• Severe abdominal pain or cramping

Always trust your instincts. If something doesn’t feel right, it’s better to be cautious and reach out to your provider.

Looking Ahead

With less than 10 weeks to go, it’s natural to feel a mix of excitement and nervousness. Your body is doing extraordinary work, and your baby is growing stronger each day. Week 31 is all about preparation—both mentally and physically. Whether you’re finalizing your birth plan or simply resting more often, everything you’re doing counts.

Next week, we’ll explore what happens in Week 32 of pregnancy—more growth, more changes, and more support. Until then, be gentle with yourself, stay informed, and keep blooming. 🌸
