What’s happening with the baby at 33 weeks pregnant?

Skull flexibility

Your baby’s skull bones aren’t fully fused yet, which helps them move and overlap during birth, making it easier for your baby to fit through the birth canal. This flexibility also supports brain growth after birth.

Skin is smoothing out

Your baby’s skin is becoming softer, less wrinkled, and less transparent. This change happens as fat builds up under their skin, making them look more like a newborn.

Active movements

Your baby is still stretching, kicking, and moving, but with less room in the womb, the movements feel more defined rather than big flips or somersaults. Kicks may be stronger and might even target your ribs.

Brain development in overdrive

Your baby’s brain is rapidly growing, tripling in weight during the last trimester. New grooves and folds are forming, creating more surface area for brain development and future learning.

Lung development continues

While your baby’s lungs are developing quickly, they still need more time to mature fully. They’re producing surfactant, a substance that helps keep the lungs inflated for breathing after birth. If your baby is born early, they might need extra support to breathe.

How big is your baby at 33 weeks pregnant?

At 33 weeks pregnant, your baby is about the size of a pineapple. They measure approximately 44.1 cm from head to toe and weigh around 2.16 kg. Your little one is steadily gaining weight and filling out as fat accumulates under their skin, preparing them for life outside the womb.

How is your belly at 33 weeks pregnant?

At 33 weeks pregnant, your belly is likely quite prominent as your baby and uterus continue to grow. Here’s what you can expect:

• Height of the uterus: Your uterus is now about 12.7 cm above your belly button, giving your belly a rounded and full appearance.

• Skin changes: You may notice your skin feeling tight or itchy as it stretches. This is common, but staying moisturized can help relieve discomfort.

• Belly button changes: For many women, the belly button becomes flat or pops out due to the pressure. This is temporary and will usually return to normal after delivery.

• Stretch marks: As your belly expands, stretch marks may appear. Their appearance varies from woman to woman and is influenced by genetics and skin elasticity.

• Shifting center of gravity: Your growing belly can affect your balance, so you may feel a bit off-center at times. Wearing supportive shoes can help.

Common symptoms and how to manage them?

1) Trouble sleeping

Discomfort, frequent urination, and an active baby can make restful sleep elusive. Use a pregnancy pillow for support, experiment with different sleeping positions (preferably on your left side), and establish a relaxing bedtime routine.

2) Frequent urination

Your growing uterus puts pressure on your bladder, causing more trips to the bathroom. Avoid caffeine, limit fluids before bedtime, and take your time to completely empty your bladder when you pee.

3) Back pain

The extra weight and shifting center of gravity strain your lower back and pelvis. Practice good posture, wear supportive shoes, and consider prenatal yoga, stretching, or massages to alleviate pain.

4) Swollen feet and ankles

Fluid retention and poor circulation cause swelling, especially in your lower body. Elevate your feet when sitting, stay hydrated, and avoid standing for long periods.

5) Braxton Hicks contractions

These practice contractions may feel like tightening or mild cramps in your abdomen. Rest, stay hydrated, and change positions. If the contractions become regular or painful, contact your doctor.

6) Heartburn and indigestion

Hormones relax the muscles in your digestive tract, and your growing baby pushes on your stomach. Eat smaller meals, avoid lying down right after eating, and stay away from trigger foods like spicy or fatty meals.

7) Shortness of breath

Your baby’s position and your expanding uterus put pressure on your diaphragm, making it harder to breathe deeply. Slow down, sit or stand upright, and practice deep-breathing exercises. This should improve as your baby drops closer to delivery.

8) Carpal tunnel syndrome

Swelling in your hands and wrists can compress nerves, causing pain or numbness. Avoid repetitive wrist movements, use wrist splints, and rest your hands frequently.

9) Swollen labia

Increased blood flow and pressure in the pelvic area can cause swelling. Use cold compresses for relief, wear supportive undergarments, and change positions regularly to reduce pressure.

10) Mood swings or anxiety

Hormonal changes and the anticipation of birth may cause emotional ups and downs. Talk to your partner or a trusted friend, practice mindfulness, or consider speaking with a counselor for extra support.

Frequently asked questions at 33 weeks pregnant

Is it normal to feel fewer baby movements at 33 weeks?

Yes, it’s normal for movements to feel different as your baby has less room to move around. However, the frequency of movement should stay consistent. If you notice a significant decrease or no movement at all, contact your healthcare provider.

How can I tell if my water has broken?

When your water breaks, it can feel like a sudden gush or a steady trickle of fluid. Amniotic fluid is usually clear and odorless. If you're unsure, wear a pad and monitor the fluid, then call your doctor for confirmation.

What should I pack in my hospital bag?

Start packing essentials like comfortable clothes, toiletries, a phone charger, baby clothes, a car seat, and important documents like your ID and insurance card. Also, include snacks and items for labor comfort, like a water bottle or a pillow.

Can I travel at 33 weeks pregnant?

Travel is typically not recommended after 32–34 weeks of pregnancy, especially by air. If travel is necessary, consult your doctor and stay close to healthcare facilities in case of emergencies.

Is it safe to have sex at this stage of pregnancy?

If your pregnancy is low-risk, sex is generally safe. However, avoid it if you have conditions like placenta previa, preterm labor, or if your doctor advises against it. Always check with your provider if you're unsure.

Should I start doing kick counts?

Yes, kick counts help monitor your baby’s health. Choose a time when your baby is usually active, and count 10 distinct movements within 2 hours. If movements are fewer or feel different, notify your doctor.

What happens during prenatal visits at this stage?

Your doctor will check your weight, blood pressure, and urine. They’ll measure your fundal height, listen to your baby’s heartbeat, and monitor for signs of complications like preeclampsia. If needed, they might discuss labor plans or order additional tests.
