At a Glance: Week 29
At 29 weeks pregnant, you are firmly in the third trimester with roughly 11 weeks to go. Your baby is about the size of a butternut squash, measuring around 38.6 cm (15.2 inches) and weighing roughly 1,150 grams (2.5 pounds). The defining theme of this week is rapid brain growth — your baby's brain is gaining billions of new neurons and forming the folds that will allow human-level cognition. Your baby's movements may feel stronger and sometimes uncomfortable as space becomes tighter. Many parents notice distinct sleep-wake patterns now.
Your Baby's Development This Week
Week 29 is a period of intense neurological and metabolic maturation:
- Brain: The brain is now developing the surface folds (gyri and sulci) that distinguish a mature human brain from earlier smooth stages. Roughly 250,000 new neurons are being created every minute. Synaptic connections are forming at a remarkable pace.
- Muscles and lungs: Muscles are gaining strength, and the lungs continue producing surfactant in greater amounts. Your baby is practicing breathing movements with amniotic fluid.
- Energy reserves: White fat continues accumulating — this provides insulation, supports temperature regulation, and gives newborns the smooth, rounded appearance.
- Bones: Bones are hardening (ossifying) and absorbing calcium from your bloodstream. The skull remains flexible to allow passage through the birth canal.
- Senses: Taste buds are functional. Hearing is well-developed. Your baby may startle to loud noises and calm to familiar voices or music.
- Sleep cycles: Distinct REM and non-REM sleep cycles are observable. Your baby sleeps the majority of the day, often in cycles of 20 to 40 minutes.
Your Body and Symptoms This Week
Many of the symptoms that started in late second trimester intensify. Common experiences at week 29 include:
- Restless legs syndrome — uncomfortable urges to move legs, especially at night
- Varicose veins or hemorrhoids from increased venous pressure
- Constipation from progesterone-slowed digestion and iron supplements
- Increased fatigue as carrying extra weight and disrupted sleep take a toll
- Stretch marks on belly, hips, breasts, and thighs
- Pelvic pressure and round ligament pain
- Hair and nail changes — often thicker hair due to less shedding
- Stronger fetal movements — kicks, rolls, hiccups may be visible from outside
- Frequent urination as the uterus pushes on the bladder
Nutrition: What to Eat and Avoid This Week
Your baby's brain growth demands high-quality nutrients this week. Iron and calcium needs remain elevated. Continue eating roughly 450 extra calories per day above baseline. Key nutrients:
- Iron (27 mg/day): Anemia is common in the third trimester. Combine iron-rich foods (lean meat, beans, fortified cereal) with vitamin C sources for better absorption.
- Calcium (1,000 mg/day): Crucial for skeletal mineralization. Sources: dairy, fortified plant milks, leafy greens, almonds.
- DHA (200–300 mg/day): Supports the rapid brain development happening this week. Low-mercury fatty fish or algae oil supplements.
- Fiber (28 g/day): Helps combat constipation. Sources: whole grains, beans, vegetables, fruit, chia seeds.
- Protein (~71 g/day): Tissue growth and muscle maintenance.
- Magnesium: May help with leg cramps and restless legs. Sources: nuts, seeds, leafy greens, whole grains.
Foods to avoid: raw or undercooked meat, fish, and eggs; high-mercury fish; unpasteurized dairy; deli meats unless heated; raw sprouts; alcohol. Limit caffeine to under 200 mg per day.
Movement and Exercise
Continue with regular moderate exercise unless your provider has restricted activity. At 29 weeks, modify intensity and choose lower-impact options:
- Walking (still the most accessible option for most people)
- Swimming and aqua aerobics (excellent for reducing joint and back pain)
- Prenatal yoga or stretching
- Light strength training with proper form
- Pelvic floor exercises (Kegels) — builds strength to support recovery
Avoid: exercises on your back for longer than a few minutes, contact sports, hot yoga, scuba diving, and anything with fall risk. Stop and call your provider for vaginal bleeding, fluid leakage, calf pain or swelling, painful contractions, chest pain, or decreased fetal movement after exercise.
Mental and Emotional Wellbeing
As your due date gets closer, it is normal for emotions to fluctuate. Some days you may feel deeply connected and excited; others, you may feel anxious about labor, your changing body, finances, or how your relationship will shift. Worry about your baby's health is also common.
Helpful practices this week:
- Talk to your partner regularly about both your hopes and your fears
- Schedule small joy-bringing activities each week — a coffee with a friend, a slow walk, a movie night
- Limit time spent on online birth story forums if they increase your anxiety
- Consider attending a partner-included childbirth class
- If you are struggling, ask your provider about perinatal mental health resources — early support reduces postpartum risk
Common Concerns and When to Call Your Doctor
Continue daily kick counts. Call your provider promptly for:
- Decreased fetal movement — fewer than 10 movements in 2 hours during active times
- Regular contractions (more than 4 per hour) before 37 weeks
- Vaginal bleeding or fluid leakage
- Severe or persistent headache not relieved by rest and acetaminophen
- Visual disturbances: spots, blurriness, flashing lights
- Sudden, severe swelling in face or hands
- Severe upper-right abdominal pain (possible HELLP or liver issue)
- Painful, red, swollen calf (possible blood clot)
- Intense itching of palms or soles
- Fever above 38°C (100.4°F) or signs of urinary tract infection
Tests and Appointments This Week
Week 29 typically falls between the standard GTT (24–28 weeks) and the GBS test (35–37 weeks). At this visit you can usually expect:
- Blood pressure check to screen for preeclampsia
- Urine sample to check for protein and glucose
- Fundal height measurement to confirm growth
- Fetal heart tones by Doppler
- Tdap vaccine if not yet given (recommended between 27 and 36 weeks of every pregnancy)
- Discussion of GTT results if not yet reviewed
- Anti-D immunoglobulin (RhoGAM) if Rh-negative and not yet administered
Appointments are typically scheduled every 2 weeks now.
Tips for Week 29
- Track kick counts daily at consistent times.
- Stretch your legs and hips in the evening to reduce restless legs and night cramps.
- Use a pregnancy pillow for left-side sleeping support.
- Stay hydrated — dehydration can trigger Braxton Hicks.
- Practice slow, deep breathing daily — useful both for relaxation now and for labor later.
Preparing for What's Next
Use the next few weeks to make practical progress without burning out:
- Finalize pediatrician selection
- Continue childbirth and breastfeeding classes
- Start a soft list for the hospital bag (do not pack yet — refine the list)
- Stock the freezer with easy postpartum meals if you have time and energy
- Discuss parental leave logistics with HR and your partner
- Set up the baby's sleep space following safe-sleep guidance: firm mattress, no pillows, blankets, or bumpers
Frequently Asked Questions About Week 29
Why do I have restless legs at 29 weeks pregnant?
Restless legs syndrome (RLS) affects up to 1 in 4 pregnant people, peaking in the third trimester. The exact cause is unclear, but iron deficiency, low folate, and hormonal shifts are contributing factors. Strategies that help include checking iron and ferritin levels with your provider, gentle leg stretches before bed, warm baths, magnesium-rich foods, and avoiding caffeine. Symptoms usually resolve within weeks of delivery.
Is it normal to have lower abdominal pressure at 29 weeks?
Yes. A heavy, pressing sensation in your lower abdomen and pelvis is common as your baby grows and the uterus expands. Increased blood flow, round ligament stretching, and Braxton Hicks contractions all contribute. However, pressure that comes with regular tightening (more than 4 per hour), low back pain, fluid leakage, or vaginal bleeding before 37 weeks could signal preterm labor and should be evaluated immediately.
What is the recommended weight gain by 29 weeks?
Healthy total weight gain varies by pre-pregnancy BMI. For someone of normal BMI, the ACOG recommends 25 to 35 pounds total, with most gain in the second and third trimesters at about 1 pound per week. By 29 weeks, gaining roughly 18 to 24 pounds is typical for normal BMI. Underweight individuals may need to gain more; those with higher BMI may need to gain less. Your provider tracks growth using fundal height and individualized targets.
Why am I getting varicose veins now?
Rising blood volume combined with increased pressure from your uterus on the inferior vena cava slows venous return from the legs. Progesterone also relaxes vein walls. The result is bulging, sometimes painful veins in the legs, vulva, or rectum (hemorrhoids). Mitigations: avoid standing for long periods, elevate your legs when sitting, sleep on your left side, wear maternity compression stockings, and stay hydrated. Most pregnancy-related varicose veins improve within months of delivery.
Can my baby taste what I eat at 29 weeks?
Yes. By 29 weeks, your baby has well-developed taste buds and swallows amniotic fluid, which carries flavors from your diet. Research shows babies show stronger preferences after birth for flavors their mothers consumed regularly during pregnancy. This is one reason a varied diet during pregnancy may support better acceptance of solid foods later. There is no need to avoid any safe foods you enjoy.
How can I sleep better in the third trimester?
Sleep disruption peaks in the third trimester due to physical discomfort, frequent urination, heartburn, and anxiety. Helpful strategies: sleep on your left side with a pillow between your knees and one supporting your belly, limit fluids in the 2 hours before bed (but stay hydrated during the day), eat smaller dinners to reduce heartburn, keep the bedroom cool and dark, and develop a wind-down routine. If sleep is severely disrupted or you snore loudly, ask about sleep apnea screening.
Is it safe to travel by plane at 29 weeks pregnant?
Most airlines allow flying through 36 weeks for uncomplicated pregnancies, though some require a note from your provider after 28 weeks. The ACOG considers air travel generally safe up to 36 weeks for low-risk pregnancies. Stay hydrated, walk the aisle hourly to reduce blood clot risk, wear compression socks, and choose an aisle seat. Avoid travel if you have placenta previa, preeclampsia, history of preterm labor, or any active complications. Always confirm with your provider before booking.
What does Braxton Hicks feel like at 29 weeks?
Braxton Hicks contractions feel like a sudden tightening or hardening of your entire belly, often lasting 30 seconds to 2 minutes. They are typically irregular, painless or only mildly uncomfortable, and ease when you change position, drink water, or rest. True labor contractions, by contrast, become progressively stronger, longer, and closer together regardless of activity. If you have more than 4 contractions per hour or any are painful and regular before 37 weeks, contact your provider.
Should I be doing perineal massage at 29 weeks?
Perineal massage is typically recommended starting at 34 to 35 weeks, not yet at 29 weeks. Beginning earlier offers no added benefit. When the time comes, daily 5 to 10 minute perineal massage in the final weeks may reduce perineal trauma and the need for episiotomy in first-time vaginal births, according to a Cochrane review. Your provider or childbirth educator can teach the technique closer to your due date.
Is it too early to write a birth plan at 29 weeks?
No — week 29 is a great time to start. A birth plan is not a contract but a communication tool that helps your care team understand your preferences for pain management, labor positions, monitoring, who you want present, immediate newborn care (skin-to-skin, delayed cord clamping, feeding), and unexpected scenarios like cesarean delivery. Keep it short (one page), discuss it with your provider, and stay flexible — birth often unfolds in unexpected ways.
