33 Weeks Pregnant: Symptoms, Baby Growth & What to Expect

Dear Mom-to-be, congratulations on reaching the final stretch of your pregnancy! You have now entered the 33rd week, and the countdown to your baby’s arrival has officially begun. At 33 weeks pregnant, you may experience various body discomforts, difficulty finding a comfortable sleeping position, increased fatigue, and even sudden mood swings. But remember, each sign is your body’s way of preparing for the big day.

 In this blog, let’s discuss the physical changes you might experience at 33 weeks of pregnancy and the key developments happening with your baby during this important week.

Baby Development at 33 Weeks

At 33 weeks pregnant, your baby is now about 43.7 cm long, roughly the size of a pineapple, and weighs around 2–2.3 kilograms. It’s important to remember that every baby grows at their pace, so slight variations in size and weight are completely normal.

This week marks a major milestone: most of your baby’s organs are fully developed, especially the brain and nervous system, which are now functioning well. One important change is in the skull — while the bones in your baby’s body are getting stronger, the skull bones remain soft and flexible. This change allows your baby to pass more easily through the birth canal during delivery.

Common Symptoms at 33 Weeks Pregnant

Your bump is starting to feel heavier now, and your baby’s head is likely positioned downward, getting ready for birth. As you enter the third trimester, some common signs and symptoms you may notice include:

• Painless contractions around your bump, known as Braxton Hicks contractions
• Sleeping problems
• Stretch marks
• Swollen and bleeding gums
• Pains on the side of your baby bump, caused by your expanding womb
• Piles
• Headaches
• Backache
• Indigestion and heartburn
• Bloating and constipation
• Leg cramps
• Feeling hot
• Dizziness
• Swollen hands and feet
• Urine infections
• Vaginal infections
• Darkened skin on your face or brown patches – this is known as chloasma or the "mask of pregnancy"
• Greasier, spotty skin
• Thicker and shinier hair

Changes in Your Body:

Your body may start experiencing false contractions, known as Braxton Hicks. These feel like a tightening of your bump for about 20–30 seconds and are a normal sign that your body is preparing for labour. In most cases, they’re harmless. However, if the contractions become painful, frequent, or difficult to tolerate, it’s best to consult your doctor right away.

Caution: Amniotic fluid leakage can occur during pregnancy and may be hard to distinguish from urine. Amniotic fluid is typically clear and odourless, whereas urine usually has a stronger smell.

5 Warning Signs To Watch For At 33 Weeks Pregnant

This is a very delicate phase, and the risk of premature delivery is higher. It’s important to watch out for these 5 key signs:

1. Regular contractions or abdominal tightening
2. Period-like cramps or pressure in the vaginal area
3. A “show” – when the mucus plug that seals the cervix comes out
4. A sudden gush or trickle of fluid from the vagina (your water may have broken)
5. Unusual backache that doesn’t feel normal for you

If you experience any of these symptoms, always reach out to your doctor. Early attention can make all the difference.

Trouble Sleeping at 33 Weeks Pregnant? Try These Tips

At 33 weeks pregnant, having sleep problems is common, but a few simple tips and lifestyle changes can help you cope and sleep better. Here are the few tips 

1. Sleep on your side, preferably the left, as it's the safest position for you and your baby. If you wake up on your back, just gently roll onto your side again.
2. Elevate your legs whenever possible to ease pressure and reduce swelling.
3. Avoid caffeine late in the day; this includes coffee, tea, cola, energy drinks, and even chocolate.
4. A warm, milky drink before bed can help relax your body and prepare you for restful sleep.
