At 33 weeks pregnant, your baby’s development is ramping up as they prepare for the world outside. Their brain is advancing quickly, fine-tuning senses like hearing and touch, which will become essential for recognizing your voice and connecting with the environment after birth.
With each passing day, they’re building the skills and responses needed for those first moments in your arms.
You may feel these changes as your baby moves actively, their kicks and stretches more distinct and regular. Tracking these movements can offer reassurance of their health and readiness.
Additionally, their immune system is strengthening, with antibodies being passed from you to support their ability to fight infections after birth. Each of these final stages signals that your baby is preparing for a strong start in the outside world.
Your Baby at 33 Weeks
At 33 weeks, your baby is around the size of a butternut squash, showing more defined features as they prepare for life outside the womb.
Fetal Position
With limited space in the womb, your baby is often in a head-down, fetal position, though adjustments in positioning can still occur in the coming weeks. These movements may feel more like small jabs and nudges as space becomes tighter, providing reassurance of their activity.
Lungs and Breathing Practice
While your baby’s lungs aren’t fully mature yet, they’re producing surfactant, a substance essential for lung expansion and breathing after birth. Through practice “breaths” of amniotic fluid, they’re strengthening their respiratory system to prepare for their first breath outside.
Bone and Skull Development
Bones continue to harden, but the skull remains soft and flexible to support a safe delivery through the birth canal. This flexibility will also support growth post-birth, a crucial feature for newborn development.
Brain and Sensory Growth
Rapid brain development is enhancing your baby’s sensory capabilities, with responses to sound and light becoming more frequent. By now, they can recognize familiar voices, especially yours, which supports bonding and sensory awareness for life after birth.
Each milestone your baby reaches now is a step closer to being ready for their arrival, preparing both their body and senses for the world outside.

Your Body at 33 Weeks Pregnant
At 34 weeks, your body is in the final stages of preparing for labor and delivery, with noticeable adjustments to support your baby’s growth and the upcoming birth.
Pelvic Pressure and Belly Expansion
With your baby settling lower in your pelvis, you may feel increased pressure in your lower abdomen. This change in position often leads to a heavier belly and can alter your posture, affecting balance as your center of gravity shifts.
Hormonal Shifts
Significant hormonal changes continue to affect your body, softening ligaments and joints, especially around the pelvis, to prepare for childbirth. These hormonal shifts may also contribute to occasional mood fluctuations as your body adjusts.
Increased Blood Flow and Swelling
As blood volume reaches its peak, you might experience more noticeable swelling, particularly in your hands, feet, and legs. This increased blood flow supports both you and your baby, preparing you for the demands of delivery.
Skin and Stretch Marks
With your belly expanding, skin stretching is common, and stretch marks may appear on your abdomen, breasts, and thighs. Applying moisturizing creams can help soothe any itchiness or dryness as your skin adapts.
Preparing for Labor
Your body may also begin to experience more “practice” or Braxton Hicks contractions as your uterus readies itself for labor. These irregular contractions play a role in strengthening the uterine muscles, helping prepare your body for the real contractions of labor.

Pregnancy Symptoms at 33 Weeks
At 34 weeks pregnant, it's common to experience symptoms as your body adapts to the final stages of pregnancy. Here's a breakdown:
Back Pain
As your belly grows, back pain can become more frequent due to the added weight and change in your center of gravity. Gentle stretches, good posture, and prenatal yoga may help reduce discomfort.
Heartburn
Heartburn often intensifies around this stage, largely due to your expanding uterus pressing on the stomach and relaxing digestive muscles. Small, frequent meals and avoiding spicy foods can help ease this symptom.
Shortness of Breath
As the uterus rises, it can put pressure on the diaphragm, causing a feeling of breathlessness. Slow, deep breaths may provide some relief, and it often helps to sit or stand up straight to give your lungs more room.
Braxton Hicks Contractions
Braxton Hicks, or "practice" contractions, may become more noticeable. These contractions are usually irregular and mild, helping your body prepare for labor. However, if they become regular or more intense, it may be wise to consult your healthcare provider to rule out preterm labor.
Pelvic Pressure
With the baby’s head moving downward, you may feel added pressure in the pelvic region. This is generally a normal part of late pregnancy, as your body readies for labor.
Frequent Urination
The baby’s position also puts pressure on your bladder, which may increase your trips to the bathroom. Staying hydrated is essential, so try to avoid limiting your fluid intake despite the frequent urination.
Insomnia
Sleep may become more challenging due to discomfort, the need to urinate more often, and general restlessness. Establishing a calming bedtime routine and using supportive pillows can improve sleep quality.
Carpal Tunnel Syndrome
Tingling or numbness in the hands can arise from fluid retention pressing on nerves, leading to carpal tunnel syndrome. Wrist splints or gentle stretches may help alleviate these symptoms.
Headaches
Headaches can also be common due to hormonal shifts, fatigue, or dehydration. Staying hydrated and practicing relaxation techniques can help manage them.
Warning Signs
Be alert for signs of preterm labor, such as regular contractions, increased pelvic pressure, or unusual discharge. Contact your healthcare provider if you notice any of these symptoms to ensure everything is progressing safely.
These symptoms are a natural part of late pregnancy, but it's important to monitor any changes closely to maintain comfort and health in these final weeks.
Tips for a Healthy Pregnancy at 33 Weeks
As you enter week 33, focusing on both comfort and essential preparations can help you feel more organized and at ease. Taking small steps now can reduce stress later, making it easier to enjoy these final weeks before your baby arrives.
Prioritize Comfort
At this stage, a pregnancy pillow can be invaluable for sleep support. Positioning the pillow to cushion your belly and back can alleviate the back and hip discomfort that often accompanies the third trimester, helping you get the rest you need.

Nesting Urge
With nesting instincts setting in, you may feel driven to organize and prepare your home. Channel this energy into practical tasks, like setting up the nursery or arranging baby supplies, but remember to take breaks to avoid exhaustion. Keeping your environment calm and organized can make the transition smoother once your baby is home.
Packing the Hospital Bag
Preparing a hospital bag now ensures you’re ready for delivery. Essentials include:
- Comfortable clothes and toiletries
- Important documents
- Snacks for yourself and your partner
Using a checklist can keep you on track and help make sure nothing is forgotten.
Installing the Car Seat
Consider installing the car seat ahead of time to eliminate last-minute stress. Ensuring it’s properly secured provides peace of mind, and many resources are available to help if you’re unsure about installation.
Finalizing Your Birth Plan
This is a good time to finalize your birth plan, covering topics like pain management and delivery options. Discussing your preferences with your healthcare provider allows you to feel more prepared and in control as your due date approaches.
