Pregnancy Week 29: Baby Size, Symptoms and Checkups (India)

• Your baby is roughly 38 cm long and weighs about 1.1–1.2 kg (around the size of a butternut squash) and is gaining about 200 g a week from now.
• The brain is growing fast and folding into ridges and grooves; survival if born now is over 90% at a NICU equipped for very preterm babies.
• Common symptoms include worsening heartburn, breathlessness, back pain, leg cramps, swelling and trouble sleeping — all usually normal.
• Daily kick counting matters from now on; fewer or weaker movements than usual is a red flag that needs same-day evaluation.
• Key India-specific steps in this window: Tdap vaccine (ideally 28–32 weeks), Anti-D at 28 weeks if you are Rh-negative, and an anaemia recheck.
• Vaginal bleeding, leaking fluid, regular painful contractions before 37 weeks, severe headache with vision changes or sudden swelling all need urgent care.

At 29 weeks your baby measures about 38 cm from head to heel and weighs around 1.1–1.2 kg — roughly the size of a butternut squash. From now until term your baby will put on about 200 g every week, filling out as fat builds up under the skin and smooths out the wrinkles.

This is a big week for the brain. The surface is folding into ridges and grooves (gyri and sulci), and the brain is taking over control of body temperature and rhythmic breathing-practice movements. The lungs keep maturing and making surfactant, the substance that lets the air sacs open after birth.

Other changes this week: the eyes can open and close and react to light; vernix (the waxy coating) and fine lanugo hair are still present; the bone marrow is now in charge of making red blood cells; and your baby is busy laying down iron stores that will last through the first few months of life.

Movements are strong and frequent now, with a recognisable pattern. You may see the bump shift, and you might feel rhythmic little jerks for a few minutes at a time — these are hiccups and are completely normal. The heartbeat is around 120–160 beats per minute.

Inside your body, your blood volume is now roughly 45–50% above pre-pregnancy levels and your heart is working harder. The top of your uterus (fundus) sits about 29 cm above your pubic bone, your centre of gravity has shifted forward, and a little breathlessness is expected as the uterus presses up against your lungs. Insulin resistance is at its peak in this trimester, which is one reason gestational diabetes screening is done in this window.

Most week-29 symptoms carry over from earlier in the third trimester, often a little more intense as the bump grows. None of the following are usually a cause for worry on their own, but tell your doctor if any are severe or new.

If a symptom is interfering with daily life, there is almost always a safe way to manage it — you do not have to simply put up with it.

By 29 weeks the bump is clearly visible whatever your build. At each visit your doctor measures fundal height — the distance from your pubic bone to the top of the uterus — which roughly matches the number of weeks (about 29 cm now). A difference of more than 2–3 cm from expected may lead to a growth scan to check your baby's size and the amount of amniotic fluid.

Your skin is changing too. The linea nigra (the dark line down the middle of your belly) is prominent in most women, and darker patches on the cheeks, forehead and upper lip (melasma) can show up, especially noticeable on Indian skin tones — this usually fades after delivery.

Stretch marks (striae) may appear on the bump, breasts, thighs and hips — pink or red at first, fading to silvery lines over months. Whether you get them is mostly down to genetics; creams and oils (coconut oil, almond oil, vitamin E, or brands like Bio-Oil and Mamaearth, roughly Rs 200–1,500) keep skin moisturised and comfortable even though the evidence for preventing marks is limited. See caring for stretch marks and silvery skin.

Comfort tips for the growing bump: well-fitted supportive bras a size or two larger; loose, breathable clothing (drawstring kurtas and stretchy leggings are as good as dedicated maternity wear, and many women find traditional clothing more comfortable now); flat or low supportive footwear, not new high heels; and a maternity support belt (Rs 500–2,500) if back or pelvic pain is bothering you. Many women sleep better with a pillow between the knees and one under the bump.

From the second trimester onward, sleeping on your left side is preferred — it improves blood flow back to the heart and to your baby.

On skin products, avoid retinoids (Retin-A, tretinoin, isotretinoin) as they are unsafe in pregnancy; daily broad-spectrum sunscreen (SPF 30+) helps reduce melasma; and gentle moisturisers ease the itch of stretching skin. One important caution: severe itching, especially on the palms and soles, needs liver tests to rule out obstetric cholestasis — do not dismiss it.

A note on cultural pressure: in many Indian families a visible bump invites a lot of comments — about size, shape, or guesses about the baby's sex. You are free to deflect intrusive questions and you owe no one an explanation. Note that revealing the baby's sex is illegal in India under the PC-PNDT Act.

From around 28 weeks, antenatal (ANC) visits usually move to every 2–3 weeks, becoming weekly after 36 weeks. The standard Indian schedule (per WHO and the Ministry of Health and Family Welfare) works out to roughly 8–12 visits, with more if your pregnancy is higher-risk — for example with gestational diabetes, high blood pressure, anaemia, twins, a previous preterm birth or a prior caesarean. If any of these apply, your doctor will add visits and extra monitoring.

A routine week-29 visit typically includes: weight check, blood pressure (watching closely for signs of preeclampsia), a urine dipstick for protein and sugar, fundal height, your baby's heartbeat on a handheld Doppler, a review of your kick counts and supplements, and time for your questions.

Two India-specific items belong in this window. First, the Tdap vaccine. The Indian Academy of Pediatrics and FOGSI recommend a single Tdap dose between 27 and 36 weeks (ideally 28–32 weeks for best antibody transfer). Your antibodies cross the placenta and protect your newborn from whooping cough until their own vaccines start at 6 weeks — important because pertussis can be life-threatening in tiny babies. It is safe and well-studied; expect at most a sore arm. Private cost is about Rs 500–1,200; it is free at government facilities. See why the Tdap shot matters and how to get it.

Second, Anti-D for Rh-negative mothers. If your blood group is Rh-negative and your partner is Rh-positive or unknown, a routine dose of Anti-D immunoglobulin at 28 weeks prevents your body from reacting against your baby's blood, which protects future pregnancies; another dose is given within 72 hours of birth if your baby is Rh-positive. About 5–7% of Indians are Rh-negative. Private cost is roughly Rs 2,500–5,000; it is free at government tertiary hospitals and under Ayushman Bharat. Supply can be patchy, so confirm availability ahead of time. See Rh incompatibility and Anti-D in India.

Other tests often done in this window: a repeat haemoglobin check for anaemia (very common in Indian pregnancies); urine culture if there are symptoms; a growth scan if there is any size–dates mismatch; and, for higher-risk pregnancies, fetal monitoring such as a non-stress test (NST) or biophysical profile from 28 weeks onward.

On access: all of this is free at government PHCs, CHCs, district hospitals and medical colleges under JSSK (Janani Shishu Suraksha Karyakram), which also covers tests, medicines, delivery and the 102 ambulance. On the 9th of every month, PMSMA offers free specialist antenatal consultations at government facilities — especially useful if you are high-risk. In the private sector, expect Rs 500–2,500 per visit.

In the third trimester you need only about 450 extra calories a day over your pre-pregnancy baseline — this is not 'eating for two.' Quality matters more than quantity, with the focus on protein, iron, calcium and vitamin D.

Protein needs rise to about 71 g a day (roughly 1.1 g per kg of pre-pregnancy weight) per ICMR. Good vegetarian sources: dal (a cup of cooked dal has 15–18 g), sprouts, paneer (100 g has 18–20 g), curd, milk, soya chunks (a cup cooked has 25–30 g), and nuts and seeds. Everyday combinations like dal-rice, rajma-chawal, idli-sambar, khichdi, dhokla and dahi-paratha give complete protein. Non-vegetarians can add well-cooked eggs, chicken, and small fish like sardines and mackerel (which are also rich in omega-3); avoid large predatory fish such as shark and swordfish for their mercury.

Iron is especially important now, as your baby builds stores for the first 4–6 months of life and your blood volume keeps expanding. With more than half of pregnant Indian women anaemic (NFHS-5), most need a supplement — usually 60 mg of elemental iron daily, higher if anaemic. Take it with a vitamin C source (lemon or orange) and away from tea, coffee and calcium for better absorption. See iron-rich Indian foods for pregnancy.

Calcium needs are 1,000 mg a day — from dairy, ragi (finger millet), sesame seeds, almonds and drumstick (moringa) leaves, with a supplement if your diet falls short. Vitamin D deficiency is very common in India despite the sunshine, so most women take a supplement (for example 60,000 IU monthly or 1,000–2,000 IU daily). Your prenatal supplement regimen ties all of this together.

Foods commonly questioned in Indian homes, with an evidence-based view: small amounts of ripe (yellow, sweet) papaya are safe and nutritious — it is unripe, green papaya in large quantities that is best avoided. A normal serving of ripe pineapple is fine. Genuinely worth avoiding are raw or undercooked meat, fish and eggs; unpasteurised dairy; high-mercury fish; more than about 200 mg of caffeine a day (one coffee or 2–3 cups of tea); all alcohol; and cut fruit or food from sources with hygiene concerns.

On traditional foods: ghee, almonds and dates are nutrient-dense and fine in moderation, jaggery is a modest iron source but still sugar, and coconut water and buttermilk are excellent for hydration. Avoid herbal or Ayurvedic preparations without checking with your doctor first, as their purity and contents vary widely.

Aim for about 2.5–3.5 litres of fluids a day, more in summer. Water is best, supplemented by coconut water, buttermilk and lemon water; keep ORS handy in hot weather or after any vomiting or loose motions.

Staying active is strongly recommended unless your doctor has advised otherwise. WHO, FOGSI, ACOG and RCOG all endorse moderate exercise in pregnancy because it helps control weight gain, lowers the risk of gestational diabetes and preeclampsia, eases back and pelvic pain, improves mood and sleep, and is linked to easier labour and faster recovery.

Aim for about 150 minutes of moderate activity a week (around 30 minutes, 5 days a week), plus light strength work twice a week and daily pelvic floor exercises. Use the 'talk test' to gauge intensity: you should be able to chat but not sing.

Good options now: brisk walking (the most accessible choice — parks, malls or a treadmill); swimming and aqua-aerobics (buoyancy supports the bump and eases swelling); a recumbent stationary bike; and prenatal yoga with props (avoid hot yoga). See our guide to safe prenatal yoga.

Pelvic floor (Kegel) exercises matter more in the third trimester as the uterus presses down. Find the muscles by briefly stopping your urine mid-stream once (only to identify them), then squeeze for 5–10 seconds and release, doing 10–15 reps a few times a day. Done consistently, they lower the risk of urinary leakage and prolapse later. See how to do Kegels correctly.

Modifications for this stage: avoid lying flat on your back for long after about 16–20 weeks (use a tilt or lie on your side); mind your balance and your relaxin-loosened joints; skip deep abdominal moves like full sit-ups and planks; and dial back on hot days or after a poor night's sleep.

Avoid throughout pregnancy: contact sports, anything with a fall risk (riding, skiing, outdoor cycling on Indian roads), scuba diving, high altitude without acclimatisation, and hot yoga, saunas or very hot baths that raise your core temperature.

Stop and call your doctor if you have vaginal bleeding, regular contractions (more than 4–6 an hour before 37 weeks), leaking fluid, dizziness or fainting, chest pain, a bad headache, calf pain or swelling, or reduced fetal movement.

Two practical India notes: in summer, exercise in the cooler early morning or evening and hydrate hard; in winter, check the AQI in northern cities and stay indoors when pollution is high (AQI over 200). And push back gently on the 'pregnancy means complete bed rest' idea — that advice is wrong for the vast majority of healthy pregnancies.

Some symptoms need same-day medical attention. Do not wait for your next scheduled visit if you notice any of the following — call your doctor or go to the nearest hospital with maternity services.

Reduced fetal movement deserves special mention. Once your baby's pattern is established (from around 28 weeks), fewer or weaker movements than usual is one of the most important warning signs and should never be ignored. Lie on your left side after a meal or a sweet drink and count distinct movements: 10 movements within 2 hours is reassuring. If you do not reach that, do not wait until morning — go in for an NST or biophysical profile the same day. Prompt checking can prevent stillbirth.

If you have severe depression, hopelessness or thoughts of harming yourself, this is also an emergency — call iCall (9152987821), Vandrevala Foundation (1860-2662-345), AASRA (9820466726) or NIMHANS Tele-MANAS (14416), and tell someone you trust.

How to reach help fast: 102 (Janani Express) is the free maternal ambulance across India; 108 is the general emergency number. Save your doctor's number, your hospital's emergency line, your blood group and your family contacts where you can find them quickly.

Your emotional health deserves the same care as the physical changes. Many women in the third trimester feel a mix of excitement and anxiety — about labour, the baby's health, finances, work, and family dynamics. Nesting urges and mood swings are common. All of these feelings are valid; the idea that a pregnant woman should be uniformly joyful does not match reality.

Mental health conditions in pregnancy are common and treatable. Antenatal depression affects roughly 15–20% of pregnancies in India, and anxiety a similar share. Untreated, they are linked to poorer outcomes for both mother and baby, so the instinct to 'tough it out' is often the wrong one. If low mood, worry or sleeplessness is affecting daily life, talk to your doctor — and read pregnancy anxiety vs depression to understand the difference.

Help comes in many forms: talking therapy such as CBT is highly effective and is offered in-person and online; counselling and tele-therapy are widely available in India (roughly Rs 500–3,000 a session); and where medication is needed, several antidepressants (sertraline is the most studied) are considered safer than untreated illness — a perinatal-aware psychiatrist can guide you. Crisis lines include iCall (9152987821), Vandrevala Foundation (1860-2662-345) and NIMHANS Tele-MANAS (14416).

An India-specific note: cultural expectations of gratitude can make it hard to admit you are struggling, and the focus on the baby can sideline the mother's wellbeing. You have every right to ask for and receive proper care, and antenatal depression is best treated when it is first noticed rather than waiting for it to 'pass after delivery.'

On the brighter side, this is a lovely time to bond. Strong, regular movements, daily kick counts, talking or singing to your baby, and resting a hand on your belly all build connection — and partners can often feel the baby move from the outside now. There is no single 'right' way to bond; some feel it strongly before birth and others more afterward, and both are normal.

Partner involvement makes a real difference now. Helpful things a partner can do: ask how she is feeling without pressure to be cheerful; attend ANC visits and share in decisions about vaccines, hospital choice and the birth plan; learn about labour together through a childbirth class; take on more of the household load; and act as a buffer against well-meaning but conflicting family advice.

In a joint family there is genuine support — cooking, company, help with older children — alongside real challenges, such as advice that conflicts with medical guidance or pressure around ceremonies. A useful approach is to agree that medical decisions rest with the mother and her doctor, use 'my doctor said' as a polite shield, and acknowledge elders' suggestions warmly even when you do not act on them.

Around this point many families hold the traditional baby shower — Godh Bharai in much of the north and west, Seemantham or Valaikappu in the south, Shaad in Bengal, Shrimanta or Dohale Jevan in Maharashtra. These usually fall in the seventh or eighth month (weeks 28–32), timed for when preterm risk has eased, and centre on blessings, gifts, bangles and the mother's favourite foods. Enjoy what is meaningful to you, but do not let it become a stressful obligation in a tiring trimester.

Now is a good time for practical planning too: confirm your maternity-leave dates (India's Maternity Benefit Act gives 26 weeks of paid leave for the first two children at establishments with 10 or more employees, usually started around weeks 34–36); start thinking about your hospital bag, which most people pack at 34–36 weeks; and discuss your birth plan and postpartum help (a japa maid typically costs Rs 10,000–25,000 a month).

If your situation involves pressure over the baby's sex, coercion or any form of abuse, please reach out: revealing fetal sex is a crime under the PC-PNDT Act, and helplines include 181 (women's helpline), 1091 (women's safety) and Vandrevala Foundation (1860-2662-345). Your healthcare team should know about anything seriously affecting your wellbeing — it is part of your care.

Costs in this window cover the routine ANC visit plus any tests, vaccines and Anti-D. In the private sector a routine visit runs Rs 500–2,500; at government facilities every visit, test, scan, vaccine, delivery and ambulance is free under JSSK.

Typical private-sector costs: glucose tolerance test Rs 500–1,500; haemoglobin recheck Rs 200–600; urine routine and culture Rs 100–500; a growth scan Rs 1,500–3,500; an NST Rs 500–1,500; Tdap vaccine Rs 500–1,200; and Anti-D (if Rh-negative) Rs 2,500–5,000. Monthly supplements add roughly Rs 500–2,500.

Schemes worth knowing and using: JSSK for free, comprehensive government maternity care; PMSMA for free specialist consultations on the 9th of each month; PMMVY, a Rs 5,000 cash benefit for the first live birth; and JSY support for institutional delivery. Several states add their own schemes — for example Tamil Nadu's Dr Muthulakshmi Reddy Maternity Benefit Scheme.

On insurance: check your employer or personal health policy for maternity cover, including any waiting period and per-claim sub-limits, well before your due date. Ayushman Bharat (PMJAY) covers eligible low-income families for ANC, delivery, vaccines and complications, while CGHS and ESI cover central-government and organised-sector workers.

Costs people forget to budget for include transport to visits, childbirth classes (Rs 3,000–15,000), a breast pump (Rs 2,000–15,000), maternity and baby supplies, and postnatal help. Planning early — and using the JSSK and PMMVY route where possible — keeps out-of-pocket costs manageable.
