Pregnancy week 33 brings you deeper into the third trimester and into an important phase of rapid fetal brain development, weight gain, bone maturation and preparation for birth.

The fetus is increasingly newborn-like, but several crucial developmental processes are still underway. The brain continues growing rapidly, more fat forms beneath the skin, the bones become harder, and the skull remains deliberately soft and flexible to support continued brain growth and eventual passage through the birth canal.

For the pregnant person, week 33 may bring more pelvic pressure, tiredness, sleep difficulties, heartburn and noticeable Braxton Hicks contractions. It is also an excellent time to have your hospital bag organized and understand upcoming tests such as Group B Streptococcus screening.

Quick answer: At 33 weeks pregnant, the fetus is around 43.7 cm from head to heel, approximately the size of a pineapple according to NHS guidance. The brain and nervous system are highly developed, bones are hardening while the skull remains flexible, fat continues accumulating, and the fetus may increasingly settle into a head-down position.

Is 33 Weeks Pregnant in the Third Trimester?

Yes.

The third trimester begins at 28 weeks.

Week 33 places you in the later part of pregnancy, with roughly seven weeks remaining until a 40-week estimated due date.

A due date remains an estimate rather than a guaranteed birth date. The NHS notes that only around 1 in 20 babies are born on their estimated due date.

How Big Is the Baby at 33 Weeks?

The NHS estimates the fetus at around 43.7 cm from head to heel at week 33.

That is approximately the size of a pineapple.

Exact size varies according to:

• genetics;
• fetal sex;
• exact gestational age;
• normal biological variation;
• measurement technique.

Fruit comparisons are useful for visualization, but clinical fetal-growth assessment relies on appropriate prenatal measurements and ultrasound when indicated.

What Is Developing at 33 Weeks?

Week 33 begins ACOG’s weeks 33–36 developmental stage.

During this phase:

• the brain continues rapid development;
• bones harden;
• the skull remains soft and flexible;
• more fat forms beneath the skin;
• fingernails reach the ends of the fingers;
• the limbs become chubbier;
• the fetus may move into a head-down position for birth.

This stage is less about forming entirely new organs and more about preparing already-formed systems for life after birth.

Is the Baby’s Brain Still Growing Rapidly?

Yes.

ACOG specifically describes weeks 33–36 as a period of rapid brain growth and development.

During the final weeks, the brain continues developing connections involved in:

• movement;
• sensory processing;
• sleep regulation;
• reflexes;
• breathing control;
• feeding coordination.

Brain development does not finish at birth. It continues throughout infancy and childhood.

Is the Nervous System Fully Developed at 33 Weeks?

The NHS describes the brain and nervous system as now highly developed at week 33.

However, “developed” should not be interpreted as completely mature.

The nervous system continues refining:

• motor control;
• reflexes;
• sensory responses;
• breathing regulation;
• temperature control.

Additional time in pregnancy continues to support neurological maturation.

Are the Baby’s Bones Hardening?

Yes.

ACOG states that during weeks 33–36 the bones continue to harden.

MedlinePlus similarly describes the bones during the preceding weeks as fully developed structurally but still relatively soft while mineral storage increases.

Calcium and phosphorus are especially important for fetal bone mineralization.

Why Does the Skull Stay Soft?

Unlike many other fetal bones, the skull remains relatively soft and flexible.

The NHS explains that the skull bones stay separated for some time after birth, which helps the head move through the birth canal.

This flexibility also gives the rapidly growing brain room to continue developing.

Are Fingernails Fully Grown?

ACOG notes that during weeks 33–36, the fingernails grow to the ends of the fingers.

Nail development continues, and some full-term newborns may even have nails extending slightly beyond the fingertips.

Is the Baby Becoming Chubbier?

Yes.

More fat is accumulating beneath the skin.

ACOG notes that the limbs become increasingly chubby during weeks 33–36.

This fat helps:

• smooth the skin;
• provide energy reserves;
• support temperature regulation after birth;
• create a more newborn-like body shape.

Is the Baby Still Gaining Weight Quickly?

Yes.

Rapid fetal weight gain remains a major feature of late pregnancy.

Much of the weight added during these final weeks comes from:

• fat;
• muscle;
• growing organs;
• mineral stores.

The fetus may not become dramatically longer each week, but body mass continues increasing.

Are the Lungs Fully Mature at 33 Weeks?

Not completely.

MedlinePlus states that during weeks 31–34 rhythmic breathing occurs but the lungs are not yet fully mature.

Surfactant production continues.

Surfactant helps keep the lung’s air sacs open after birth.

Every additional week before term can support further respiratory maturity.

Is the Baby Practicing Breathing?

Yes.

MedlinePlus describes rhythmic breathing movements during weeks 31–34.

These movements exercise:

• the diaphragm;
• chest muscles;
• respiratory system.

The fetus still receives oxygen through the placenta and does not breathe air inside the uterus.

Is the Baby Storing Iron and Calcium?

Yes.

MedlinePlus notes that during weeks 31–34 the fetal body stores increasing amounts of:

• iron;
• calcium;
• phosphorus.

These nutrients support:

• blood-cell production;
• bone development;
• muscle function;
• nerve function.

Is the Baby Moving Strongly at 33 Weeks?

Yes.

Movement usually remains strong and recognizable.

You may feel:

• kicks;
• stretches;
• rolls;
• pushing;
• body shifts;
• hiccups.

Because the fetus is larger and space is tighter, movement may feel different than it did earlier.

Does Movement Decrease Because the Baby Has Less Room?

The style of movement may change, but a significant reduction should not be dismissed as lack of space.

You may notice more:

• rolling;
• stretching;
• pressing;
• pushing;

and fewer large flips.

Continue paying attention to your baby’s usual pattern.

What If Fetal Movement Becomes Reduced?

Contact your maternity healthcare provider promptly if movements become clearly reduced or stop.

Do not rely on a home Doppler for reassurance.

A heartbeat heard at home cannot confirm that fetal wellbeing is normal.

Is the Baby Head Down at 33 Weeks?

Many babies are moving toward a head-down position by this stage.

ACOG notes that during weeks 33–36 the fetus may turn into a head-down position in preparation for birth.

The NHS also notes that pelvic heaviness at week 33 can sometimes be related to a head-down fetal position.

However, not every fetus is head down yet.

What Is Head-Down Position?

A head-down, or cephalic, position means the fetal head points toward the cervix.

This is the most common position for vaginal birth.

Position may still change during the coming weeks.

What If the Baby Is Breech at 33 Weeks?

A breech baby has the bottom or feet closer to the cervix.

At 33 weeks, this does not automatically mean the fetus will remain breech.

There is still time to turn.

Fetal position usually becomes more important clinically around 36 weeks.

Does Head Down Mean Labor Is About to Start?

No.

A fetus can be head down for several weeks before labor begins.

Head-down position is a preparation for birth, not a reliable predictor of when labor will start.

Why Does My Pelvis Feel Heavy?

The NHS notes that at week 33 you may feel as though something is weighing down on your pelvis.

This sensation may be related to:

• fetal position;
• increasing uterine weight;
• pressure on the pelvis;
• pregnancy-related ligament changes.

Some pelvic pressure can occur normally.

When Is Pelvic Pressure Concerning?

Contact maternity care if pelvic pressure is accompanied by:

• regular painful contractions;
• bleeding;
• fluid leakage;
• persistent lower-back pain;
• repeated abdominal cramps.

At 33 weeks, these symptoms may require evaluation for preterm labor.

Can Braxton Hicks Become More Noticeable at 33 Weeks?

Yes.

The NHS specifically highlights Braxton Hicks contractions at week 33.

These practice contractions may feel like the uterus or bump becomes tight for a short period and then relaxes.

The NHS describes episodes lasting roughly 20 to 30 seconds on its week-33 page.

What Do Braxton Hicks Feel Like?

They may feel like:

• abdominal tightening;
• firmness;
• pressure;
• the bump briefly becoming hard.

They are generally irregular and should not progressively become:

• stronger;
• closer together;
• more painful.

When Could Contractions Be Preterm Labor Instead?

The NHS advises contacting maternity care if contractions become painful or occur at regular intervals.

Other concerning symptoms can include:

• watery fluid leakage;
• vaginal bleeding;
• pelvic pressure;
• persistent backache;
• repeated cramping.

At 33 weeks, suspected labor needs professional assessment.

Is Vaginal Discharge Normal at 33 Weeks?

White or milky pregnancy discharge may remain normal.

Seek medical advice if discharge is:

• foul smelling;
• green or yellow;
• painful;
• itchy;
• associated with fever.

A sudden gush or ongoing watery leakage needs prompt evaluation because it could represent amniotic fluid.

What About Vaginal Bleeding?

Any bleeding during late pregnancy should be medically assessed.

Seek urgent care if bleeding is:

• heavy;
• accompanied by pain;
• associated with contractions;
• associated with dizziness or fainting;
• accompanied by fluid leakage.

What Symptoms Are Common at 33 Weeks?

The NHS lists possible week-33 symptoms including:

• Braxton Hicks;
• sleep problems;
• stretch marks;
• bleeding or swollen gums;
• round-ligament discomfort;
• hemorrhoids;
• headaches;
• backache;
• indigestion;
• heartburn;
• bloating;
• constipation;
• leg cramps;
• feeling hot;
• dizziness;
• swollen hands or feet;
• urinary infections;
• vaginal infections;
• skin pigmentation changes;
• oily skin;
• thicker hair.

Not everyone will experience all of them.

Is Fatigue Normal at 33 Weeks?

Yes.

The NHS notes that many people feel very tired by week 33 because of the additional pregnancy weight being carried.

Fatigue can also be influenced by:

• interrupted sleep;
• frequent urination;
• heartburn;
• physical discomfort;
• anemia.

Discuss severe or worsening fatigue at prenatal visits.

Is Backache Normal?

Yes.

Increasing abdominal weight shifts posture and places more strain on the back.

Helpful measures may include:

• supportive shoes;
• avoiding heavy lifting;
• changing positions regularly;
• gentle activity;
• pregnancy-appropriate physiotherapy when needed.

Persistent severe pain should be assessed.

Is Heartburn Common?

Yes.

The growing uterus increases pressure on the stomach.

Pregnancy hormones also relax digestive muscles.

Helpful measures may include:

• eating smaller meals;
• avoiding personal trigger foods;
• remaining upright after meals;
• avoiding very large meals before bed.

Ask a healthcare professional about pregnancy-safe medication if necessary.

Is Constipation Normal?

Yes.

Pregnancy hormones and physical pressure on the digestive tract can slow bowel movement.

General strategies include:

• adequate fluids;
• fruit;
• vegetables;
• whole grains;
• legumes;
• regular appropriate movement.

Are Hemorrhoids Common?

Yes.

Constipation and increasing pressure in the pelvis can contribute.

Seek professional advice for:

• substantial bleeding;
• severe pain;
• symptoms that do not improve.

Are Leg Cramps Normal?

Yes.

Leg cramps can continue late in pregnancy.

Gentle stretching may help.

Seek urgent medical advice for one leg that becomes:

• unusually swollen;
• red;
• warm;
• persistently painful.

Is Swelling Normal?

Mild swelling of the feet and ankles may occur.

Sudden or substantial swelling is more concerning, especially when associated with:

• severe headache;
• visual changes;
• pain beneath the ribs;
• feeling very unwell.

These can be symptoms associated with pre-eclampsia and require medical assessment.

Are Prenatal Appointments More Frequent Now?

Often, yes.

MedlinePlus notes that prenatal visits are commonly scheduled more frequently between 28 and 36 weeks than they were earlier in pregnancy.

The exact schedule can vary according to:

• healthcare system;
• maternal age;
• medical history;
• pregnancy complications.

Higher-risk pregnancies may require additional visits or testing.

What May Be Checked at a Third-Trimester Appointment?

Depending on your healthcare system, prenatal appointments may include:

• blood pressure;
• symptoms;
• fetal movement discussion;
• uterine growth;
• fetal position;
• urine testing;
• laboratory or vaccination follow-up.

Your provider may also discuss preparation for labor and birth.

Is Special Fetal Monitoring Needed at 33 Weeks?

Not for every uncomplicated pregnancy.

ACOG notes that for many at-risk pregnancies, antenatal fetal surveillance may begin around or after 32 weeks, depending on the underlying condition.

Possible tests can include:

• nonstress testing;
• biophysical profile;
• ultrasound-based assessment.

Testing decisions should be individualized.

What Is a Nonstress Test?

A nonstress test measures fetal heart rate over time and evaluates how it responds to movement.

It is used when additional assessment of fetal wellbeing is medically indicated.

It is not automatically necessary for every 33-week pregnancy.

What Is Group B Strep?

Group B Streptococcus, or GBS, is a type of bacteria that can live in the digestive or genital tract without causing symptoms.

The NHS notes that GBS is common and that some pregnant people carry it without knowing.

The main concern is possible transmission to the baby around birth.

Is GBS Testing Done at 33 Weeks?

Usually not yet under current ACOG guidance.

ACOG recommends routine vaginal-rectal GBS screening at 36–38 weeks, with its detailed obstetric guidance specifying 36 weeks 0 days through 37 weeks 6 days.

Week 33 is therefore a good time to learn about the test, rather than assuming it must already be done.

How Is GBS Testing Done?

ACOG describes GBS screening as a culture using a swab from the:

• vagina;
• rectum.

The test helps identify pregnancies where antibiotics during labor may reduce the risk of early newborn GBS disease.

What Happens if GBS Is Positive?

ACOG states that if GBS is present, antibiotics are generally given through an IV during labor when indicated.

A positive GBS result does not mean the pregnant person is seriously ill.

It indicates colonization that may affect newborn management.

Should GBS Be Treated With Antibiotics Before Labor?

Routine GBS colonization is generally managed with antibiotics during labor rather than simply trying to eliminate the bacteria weeks beforehand.

Individual situations such as GBS urinary infection can require different management.

Follow your healthcare provider’s advice.

Is RSV Vaccination Still Possible at 33 Weeks?

Yes, depending on your country and vaccination program.

The NHS notes that its RSV vaccine is commonly offered earlier but may be given later if needed.

In the United States, ACOG’s 2026 maternal immunization schedule lists maternal RSV vaccination during the eligible seasonal window at 32 weeks 0 days through 36 weeks 6 days for eligible pregnancies.

Because vaccination recommendations differ by country, follow local guidance.

Is Tdap or Whooping Cough Vaccination Relevant?

Yes.

ACOG’s 2026 maternal immunization schedule recommends Tdap during every pregnancy between 27 and 36 weeks.

Other countries use their own schedules.

If you have not received the vaccine recommended by your healthcare system, ask your maternity provider.

Is Influenza Vaccination Safe During Pregnancy?

ACOG’s 2026 schedule recommends inactivated or recombinant influenza vaccination during pregnancy when appropriate, at any gestational age.

Season and country-specific recommendations matter.

Should You Pack Your Hospital Bag at 33 Weeks?

Yes, this is a sensible time.

The NHS specifically recommends getting a hospital bag ready around week 33 in case the baby arrives earlier than expected.

Useful categories include:

• pregnancy notes or birth plan;
• comfortable clothing;
• toiletries;
• baby clothes;
• diapers;
• postpartum supplies;
• medications;
• snacks where permitted.

Check your own hospital or birth center’s list because requirements vary.

Should You Have Important Phone Numbers Ready?

Yes.

The NHS suggests having contact details ready for:

• your maternity unit or hospital;
• your midwife;
• your birth partner;
• transport.

This reduces stress if labor or urgent symptoms begin unexpectedly.

Should You Arrange Transport to the Hospital?

Yes.

Know in advance:

• who will drive;
• alternative transport;
• where to go;
• the full address;
• where maternity admissions are located.

The NHS specifically advises against driving yourself while in labor.

Is a Car Seat Important to Prepare Now?

Yes.

The NHS week-33 guidance recommends having an appropriate car seat ready for bringing the newborn home.

Practice installing it according to:

• manufacturer instructions;
• your country’s child-restraint laws.

Do You Need Extra Calories at 33 Weeks?

The NHS states that there is no need to “eat for two.”

Under UK guidance, the third trimester may require around 200 additional calories per day.

Individual energy needs vary.

Focus on a balanced diet rather than simply increasing food quantity.

Is Iron Important at 33 Weeks?

Yes.

Iron supports:

• maternal hemoglobin;
• fetal blood production;
• fetal iron stores;
• oxygen transport.

Iron-rich foods can include:

• lean meat;
• beans;
• lentils;
• fortified cereals;
• leafy vegetables.

Supplementation should follow blood-test results and clinical advice.

Is Calcium Important?

Yes.

Late pregnancy remains an important period for fetal bone mineralization.

Calcium supports:

• bones;
• muscle function;
• nervous-system function.

Sources can include:

• dairy foods;
• fortified alternatives;
• calcium-rich plant foods.

Is Vitamin D Important?

Yes.

Vitamin D helps support bone and muscle health.

The NHS notes that some people may need a daily vitamin D supplement, with its UK guidance using 10 micrograms daily in relevant circumstances.

Recommendations differ internationally.

Can You Exercise at 33 Weeks?

Many people with uncomplicated pregnancies can continue appropriate physical activity.

The NHS recommends aiming for around 150 minutes of exercise per week during pregnancy, adjusted for comfort and ability.

Suitable activities may include:

• walking;
• swimming;
• pregnancy-adapted exercise;
• light strength work.

Avoid activities with a high risk of falling or abdominal trauma.

Are Pelvic Floor Exercises Still Important?

Yes.

The NHS continues to recommend pelvic-floor exercises during late pregnancy.

They can support:

• bladder control;
• pelvic organs;
• postpartum recovery.

Should You Still Sleep on Your Side?

Yes.

Side sleeping remains preferable later in pregnancy.

If you wake on your back, simply roll onto your side.

Pillows can support:

• the abdomen;
• knees;
• lower back.

Should You Attend Antenatal Classes?

Yes.

The NHS recommends continuing or arranging antenatal classes around this stage.

Classes may help prepare you for:

• labor;
• pain-relief options;
• cesarean birth;
• infant feeding;
• newborn care;
• partner support.

Is It Time to Finalize the Birth Plan?

This is a good time to review it.

Consider preferences about:

• place of birth;
• birth partner;
• pain relief;
• movement during labor;
• skin-to-skin contact;
• infant feeding.

A birth plan expresses preferences rather than guaranteeing exactly how labor will happen.

Should You Learn About Newborn Screening?

Yes.

The NHS specifically recommends discussing newborn screening with your maternity professional before birth.

Newborn screening programs differ by country but may include:

• blood tests;
• hearing screening;
• physical examination;
• other locally recommended tests.

Should You Think About Postpartum Contraception?

Yes.

The NHS recommends considering contraception before birth because fertility can return sooner than many people expect.

You do not have to make a final decision immediately.

Discuss suitable options with your healthcare professional.

Is Mental Wellbeing Important at 33 Weeks?

Yes.

The NHS encourages pregnant people who feel persistently anxious or low to speak with their doctor or midwife.

Late pregnancy can bring worries about:

• labor;
• parenting;
• finances;
• relationships;
• health.

Seeking support is part of prenatal care.

Can You Travel at 33 Weeks?

Travel becomes more complicated as pregnancy advances.

Before significant travel, consider:

• airline restrictions;
• documentation requirements;
• risk of preterm labor;
• access to maternity care;
• travel insurance.

Discuss long-distance travel with your healthcare provider.

Is Sex Safe at 33 Weeks?

For many uncomplicated pregnancies, yes.

Seek individual medical advice if you have:

• bleeding;
• fluid leakage;
• placenta-related complications;
• cervical concerns;
• regular painful contractions;
• instructions to avoid intercourse.

When Should You Seek Medical Help at 33 Weeks?

Seek prompt maternity assessment for symptoms such as:

• heavy vaginal bleeding;
• regular painful contractions;
• ongoing or sudden watery fluid leakage;
• severe abdominal or pelvic pain;
• a meaningful reduction or stopping of fetal movement;
• severe headache;
• visual changes;
• sudden major swelling;
• severe pain under the ribs;
• chest pain;
• sudden severe breathlessness;
• fainting;
• high fever;
• severe one-sided leg swelling or pain.

At 33 weeks, possible preterm labor, ruptured membranes, pre-eclampsia or reduced fetal movement needs professional assessment rather than online self-diagnosis.

Pregnancy Week 33 FAQs

How big is the baby at 33 weeks?

The NHS estimates the fetus at around 43.7 cm from head to heel, approximately the size of a pineapple.

What is developing at 33 weeks?

The brain continues developing rapidly, bones harden while the skull stays flexible, more fat forms beneath the skin and fingernails extend toward the fingertips.

Is the baby’s brain fully developed?

The brain and nervous system are highly developed, but maturation continues throughout the remaining pregnancy and after birth.

Are the bones hardening?

Yes. ACOG notes that bones harden during weeks 33–36 while the skull remains soft and flexible.

Are the lungs fully mature?

Not yet. MedlinePlus notes that rhythmic breathing occurs during weeks 31–34, but the lungs remain immature.

Should the baby be head down?

The fetus may move head down during weeks 33–36, but not every fetus has settled into this position at exactly week 33.

Is pelvic heaviness normal?

It can occur as the uterus becomes heavier and the fetus may move into a head-down position.

Are Braxton Hicks normal at 33 weeks?

Yes. The NHS describes them as practice contractions that may tighten the bump briefly. Painful or regular contractions require maternity assessment.

Is GBS testing done at 33 weeks?

Usually not yet under ACOG guidance. Routine screening is recommended later, around 36–38 weeks.

Is RSV vaccination possible at 33 weeks?

Yes, depending on the country and season. ACOG’s 2026 schedule includes maternal RSV vaccination at 32 weeks 0 days through 36 weeks 6 days for eligible pregnancies.

Is Tdap still recommended at 33 weeks?

In the United States, ACOG’s 2026 schedule recommends Tdap during every pregnancy at 27–36 weeks.

Should the hospital bag be packed?

This is a sensible time. The NHS specifically recommends preparing it around week 33.

Do prenatal appointments become more frequent?

Often yes. Prenatal care generally becomes more frequent between 28 and 36 weeks, although schedules are individualized.

Is special fetal monitoring routine?

No. ACOG recommends antenatal surveillance primarily when risk factors justify it; around 32 weeks or later is common for many at-risk pregnancies.

Is week 33 in the third trimester?

Yes. Week 33 is firmly within the third trimester.

What Comes Next?

During Pregnancy Week 34, rapid growth and maturation continue.

MedlinePlus groups weeks 31–34 together as a stage when:

• fetal growth is rapid;
• substantial fat is gained;
• rhythmic breathing continues;
• lungs are still maturing;
• bones remain soft despite being fully formed;
• iron, calcium and phosphorus stores increase.

The NHS also notes that a routine 34-week antenatal appointment may be scheduled within its care pathway.

Last content review: October 2026

This page provides general educational pregnancy information only. It does not diagnose preterm labor, pre-eclampsia, GBS infection, reduced fetal movement or other pregnancy complications; interpret fetal monitoring; prescribe treatment; or replace individualized prenatal care.

Fetal development, fetal position, movement patterns, vaccination recommendations and prenatal-care schedules can vary between pregnancies and countries. Contact a qualified maternity healthcare professional for individual concerns about movement, contractions, bleeding, fluid leakage, fetal position, swelling, breathing difficulty or other pregnancy symptoms.

Conclusion

Pregnancy week 33 begins an important late-pregnancy maturation stage. ACOG describes weeks 33–36 as a period when the fetal brain continues rapid development, bones harden while the skull remains flexible, fat accumulation increases, fingernails reach the fingertips and the fetus may turn into a head-down position.

The NHS estimates the fetus at around 43.7 cm from head to heel and notes that the brain and nervous system are now highly developed. Skull flexibility remains important for birth, while the fetus continues gaining fat and maturing internally.

For the pregnant person, week 33 may bring increasing pelvic heaviness, fatigue and more obvious Braxton Hicks contractions. These practice tightenings should generally remain irregular; painful or regular contractions need assessment because labor at 33 weeks would still be preterm.

This is also an important preparation week. Having your hospital bag, transport plan and maternity contact information ready can reduce stress if symptoms begin earlier than expected. It is also a useful time to learn about upcoming GBS screening and check whether any locally recommended pregnancy vaccinations remain due.

Continue routine prenatal care and awareness of your baby’s usual movement pattern. Heavy bleeding, regular painful contractions, watery fluid leakage, severe headache with visual changes, sudden major swelling or a significant reduction in fetal movement requires prompt professional assessment.
