Key takeaways

  • Your due date is an estimate, not a deadline — only ~5% of babies are born on it, and roughly half of singleton pregnancies are still pregnant at the start of week 40.
  • Baby is full term: around 50–51 cm and about 3.4 kg, with mature lungs and good iron stores.
  • Watch for the signs of real labour — regular tightening contractions, your waters breaking, or a bloody show — and know your hospital's '4-1-1' rule.
  • Decreased fetal movement is never normal at any stage. Do a kick count and go to hospital the same day if it doesn't pick up.
  • If labour hasn't started, your OB will discuss a membrane sweep and induction — most Indian OBs aim to deliver by 41 weeks because stillbirth risk rises slightly after that.
  • Call 102 (free maternity ambulance) or 108 for any heavy bleeding, severe headache with vision changes, or a sudden drop in your baby's movements.

Your baby at 40 weeks

At 40 weeks your baby is full term and measures around 50–51 cm from head to heel, weighing about 3.4 kg — roughly the size of a small pumpkin. Every organ is ready for life outside the womb.

The lungs are fully mature and producing surfactant, the substance that keeps the tiny air sacs open for that first breath. The brain is still developing fast and will keep growing rapidly for the first years of life. Most of the fine lanugo hair has shed, though a little may remain in the skin folds along with the white, waxy vernix. The bones are hardening everywhere except the skull, which stays soft and slightly mouldable so the head can ease through the birth canal.

Your baby now has good stores of iron (enough to last roughly the first 4–6 months) and a healthy layer of fat under the skin for warmth and feeding regulation. Meconium — the dark, sticky first stool — is collecting in the bowel, ready to pass after birth.

The baby's heart beats at 120–160 bpm. The placenta is mature (a Grannum grade 3 appearance is normal at term), and there is around 800–900 ml of amniotic fluid cushioning the baby.

A note on movement: there is less room to move now, so the type of movement may change — more squirms and stretches than big kicks. But the amount and pattern of movement should not drop. Keep doing a daily kick count, and contact your hospital straight away if your baby is quieter than usual.

Common symptoms at week 40

Week 40 symptoms are mostly about your body getting ready to give birth. Many women feel a mix of heavy discomfort and 'any day now' anticipation. You may notice:

Your body at week 40 in the Indian context

By the due date week, your bump is at its largest and your centre of gravity is well forward, so balance is genuinely altered. Loose, comfortable clothing matters more than ever — a drawstring kurta, leggings or a salwar with a stretchy waistband, or a maternity saree or palazzo. Slip-on flats are far easier than laces when bending is hard, and a supportive bra (often 2–3 cup sizes larger than before pregnancy) helps as your breasts prepare for feeding.

Deal kindly but firmly with the constant 'when is the baby coming?' comments from relatives and neighbours — a polite 'soon, thank you' and a change of subject is usually enough. You don't owe anyone an explanation.

Skin changes often peak now: the linea nigra (dark line down the abdomen) is prominent, melasma (chloasma) patches on the face may darken, and the nipples and areolae deepen in colour to help the baby latch after birth. Stretch marks may be developing or fully formed on the bump, breasts, hips and thighs — pink or red at first, fading to silvery white over months. Genetics largely decide who gets them. Moisturising with coconut oil, almond oil or a cream like Bio-Oil keeps skin comfortable, though the evidence that any product prevents stretch marks is weak. For more, see our guide to caring for stretch marks and silvery striae in pregnancy.

Comfort measures for the heavy final week: sleep on your left side where possible (it improves blood flow to the baby); a full-body or wedge pregnancy pillow (around ₹800–4,000) makes a real difference, as does a pillow between the knees. Sleeping propped up eases heartburn and breathlessness. A maternity support belt (₹500–2,500) can relieve back and pelvic pain, and a bath stool or long-handled brush helps when bending is difficult.

Sex in late pregnancy is safe for most women without specific contraindications such as placenta previa, ruptured membranes, or a history of preterm labour. Libido varies a lot — fatigue, body image and discomfort all play a part, and side-lying or spooning positions take pressure off the bump. After 37 weeks, the prostaglandins in semen and the oxytocin released with orgasm may have a small role in ripening the cervix, though the effect is modest. Some families discourage intercourse in pregnancy entirely; medically, that is not necessary in an uncomplicated pregnancy. Stop and get checked if there is bleeding or significant pain afterwards.

Skin-care safety: avoid retinoid creams (Retin-A, tretinoin, isotretinoin), which are not safe in pregnancy. Daily broad-spectrum SPF 30+ helps with melasma. Severe itching — especially on the palms and soles and worse at night — is a red flag: it can signal obstetric cholestasis, which needs liver function and bile-acid tests because it carries a stillbirth risk if untreated. A separate itchy rash on the bump (PUPPP) is common, harmless and treatable; mention either to your OB.

Your antenatal visit at week 40: checks, GBS, monitoring and the induction conversation

By week 40 your antenatal (ANC) visits are weekly. India's standard schedule, in line with WHO and Ministry of Health & Family Welfare guidance, runs from booking through weeks 14–20, 24, 28, 32 and 34–36, then weekly until birth — usually 8–12 visits in all, with more for high-risk pregnancies. Women with conditions such as gestational diabetes, high blood pressure, anaemia, a previous preterm birth, a prior caesarean or a small or post-term baby are monitored more closely; see who falls into these groups in our guide to high-risk pregnancy criteria in India.

What a week-40 visit covers:

Food, nutrition and the date-fruit question

In the final week your diet still needs steady protein, iron, calcium and energy — but 'eating for two' is a myth. The third trimester needs only about 450 kcal a day above your pre-pregnancy baseline, and quality matters more than quantity. Smaller, more frequent meals (three mains plus two or three snacks) sit better when a heavy uterus is pressing on your stomach and worsening heartburn.

Protein needs are around 71 g a day (ICMR), or roughly 1.1 g per kg of pre-pregnancy weight. Vegetarian sources include dal (15–18 g per cooked cup), sprouts, paneer (18–20 g per 100 g), curd, milk, soya chunks (very protein-dense), nuts and millets. Pairings like dal-chawal, rajma-rice, idli-sambar, khichdi and paneer-paratha give complete protein. Non-vegetarians can add eggs (fully cooked), chicken and small fish like sardines and mackerel — but avoid large predatory fish (shark, swordfish, king mackerel) for mercury.

Iron stays important — for the baby's stores and your own blood volume. India has very high background anaemia (NFHS-5 found 52% of pregnant women anaemic), so most women need a supplement: usually 60 mg elemental iron daily, more if anaemic. Take it with a vitamin-C source (lemon or orange) and away from tea, coffee or calcium, which block absorption. See our guide to iron-rich foods in pregnancy. Requesting delayed cord clamping (1–3 minutes) in your birth plan also boosts your baby's iron stores at birth.

Calcium (1,000 mg/day) comes from milk, curd, paneer, ragi, sesame, almonds and moringa leaves, with a supplement if your diet falls short. Vitamin D deficiency is common across India even in sunny regions; most OBs prescribe a supplement.

Dates (khajoor): there is reasonable randomised-trial evidence — largely from Iran, with some Indian replication — that eating about 5–6 dates a day from week 36–37 is linked to a more favourable cervix at admission, shorter active labour, and less need for induction or oxytocin. The likely mechanism is natural prostaglandin-like and oxytocin-like activity plus quick energy. It is low-risk for women with normal blood sugar, but dates are concentrated, high-glycaemic sugar, so women with gestational diabetes should check with their OB or dietitian first. Five to six medium dates is roughly 100–150 g.

Indian foods that suit this stage: khichdi, idli-dosa with sambar, rajma-chawal, dahi with meals, ragi porridge, jowar/bajra rotis, sprouted-moong salad, vegetable pulao with raita, fresh fruit (ripe papaya is safe and beneficial; also banana, orange, pomegranate, melon), coconut water and buttermilk.

Foods to be careful with: large quantities of unripe (green) papaya, raw or undercooked meat/fish/eggs, unpasteurised dairy and soft cheeses, high-mercury fish, more than ~200 mg caffeine a day (about one coffee), and all alcohol. Avoid cut fruit and unhygienic street food.

Hydration: aim for about 2.5–3.5 litres of fluid a day (more in summer), mostly water, with coconut water, lemon water and buttermilk. Good hydration supports amniotic fluid; dehydration can trigger more Braxton-Hicks. Keep ORS sachets handy in hot weather or after any vomiting or loose motions.

Movement, exercise and labour preparation

Gentle activity is still recommended at 40 weeks for women without contraindications — WHO, FOGSI, ACOG and RCOG all endorse staying active in a normal pregnancy. By now the goal is comfort, mobility and getting your body ready for labour, not fitness gains. The 'talk test' is the simplest intensity guide: moderate effort lets you talk but not sing.

What works well this week:

When to call your doctor or go to hospital

Some symptoms need urgent attention. Don't wait for your next ANC visit — call your OB or go to the nearest hospital with maternity services. In an emergency, call 102 (free maternity ambulance) or 108 (general emergency).

Go in straight away for:

Your emotional health in the due-date week

The final week is emotionally intense, and that is completely normal. Many women feel a swirl of excitement, impatience, and real anxiety about labour, the baby's position, and whether birth will go as hoped. Nesting urges (sudden bursts of energy to clean and prepare) often alternate with deep fatigue. Hormone shifts and broken sleep amplify all of it. For women who have had a previous loss or fertility struggles, anxiety often peaks now. The cultural expectation that an expectant mother should be serene and grateful at all times simply doesn't match reality.

Common late-pregnancy worries include birth pain and how to manage it, whether labour will start on its own, and whether a vaginal birth will be possible. India's private metro hospital caesarean rates run high (often 40–60%, well above the WHO-suggested 10–15%), so many women feel pressure toward an early caesarean recommendation that may or may not be medically justified — our guide to shared decision-making around caesarean birth can help you ask the right questions.

These feelings are valid, but they shouldn't tip into something heavier. Antenatal depression affects roughly 15–20% of pregnancies in India (ICMR), and it strongly predicts postnatal depression — so recognising and treating it early genuinely matters. Don't 'tough it out' or quietly stop medication: SSRIs such as sertraline are generally considered safer in pregnancy than untreated depression, and talking therapies like CBT are highly effective. Tele-counselling is widely available in India (Practo, YourDost, MFine and others, roughly ₹500–3,000 a session). If you are struggling, your OB can connect you with perinatal mental-health support, which continues into the postpartum period too.

Reach out for help. Lean on your partner (the single biggest support), supportive family, and any childbirth-class community you've built. In a crisis, call iCall (9152987821), the Vandrevala Foundation (1860-2662-345, 24/7), AASRA (9820466726), or the government tele-mental-health line NIMHANS Telemanas (14416).

A cultural note: the pressure to look only joyful can make it hard to share difficult feelings honestly, and attention often centres on the baby rather than the mother. Your emotional and physical wellbeing deserve equal priority, and seeking mental-health care is a sign of good parenting, not weakness.

Partner and family support this week

A supportive partner makes an enormous difference in these final days. The most useful things a partner can do are ask how she's feeling (without pressure to be cheerful), attend the weekly ANC visit, learn the labour stages and comfort measures together, take on more of the household load, and act as a buffer against well-meaning but conflicting family advice.

A partner's main job in labour is not medical — it's calm presence, advocacy (speaking her preferences to the team when she's too focused to), and comfort: back rubs, water, position help, encouragement. Knowing this in advance takes the pressure off.

The joint-family context brings real support — cooking, company, help with older children, and traditional postpartum care — alongside real friction: advice that conflicts with medical guidance, opinions on diet and rest, and pressure about the method of delivery. A simple, polite 'my OB advised this' is an effective shield. It helps to agree in advance that the pregnant woman, guided by her OB and supported by her partner, is the primary decision-maker on medical questions.

On delivery-method pressure: some families push for vaginal birth as the only 'real' way; a caesarean, when medically indicated, is safe, sometimes life-saving, and takes nothing away from motherhood. At the same time, over-eager elective caesareans (sometimes for convenience or astrological timing) are a genuine concern in some private settings. The right stance is a medical one — caesarean when it's needed, vaginal birth when there's no contraindication. It's reasonable to ask your hospital about its caesarean rate and the criteria it uses.

Practical planning: confirm your maternity-leave start (the Maternity Benefit Act gives 26 weeks paid leave for the first two children at establishments with 10+ employees), keep transport ready, and line up postpartum help — a family member, a japa maid (around ₹10,000–25,000/month) or a postpartum doula. If a family situation involves coercion, gender pressure or abuse, you can call the women's helpline 181, women's safety 1091, or the National Commission for Women on 7827-170-170 — your care team should know about anything seriously affecting your wellbeing.

Looking ahead to the first hour: plan for immediate skin-to-skin contact and early breastfeeding — both are evidence-based and easy to request in your birth plan, and the skin-to-skin contact of those first minutes helps regulate your baby's temperature, breathing and feeding.

Costs and access to care this week

Week-40 costs are mostly the weekly ANC visit plus any tests or monitoring, and then your delivery package. At government facilities, everything — visits, tests, scans, delivery, NICU and postnatal care — is free under JSSK.

Week 40 myths, corrected

Myth: 'Induction always leads to a caesarean'

  • Not true. Older studies seemed to link induction with more caesareans, but they compared induced women to those in spontaneous labour — a misleading comparison, since women are often induced for medical reasons that themselves raise caesarean risk. More recent randomised trials comparing induction at 39 weeks with waiting (such as the ARRIVE trial, 2018) found similar or even slightly lower caesarean rates with induction.
  • What it means for you: if your OB recommends induction at 40–41 weeks for a medical reason (post-term, preeclampsia, GDM, reduced movements, cholestasis, low fluid), the indication makes induction the right choice. Modern methods — cervical ripening, a Foley catheter, oxytocin or breaking the waters — are safe and effective when used appropriately. Choosing an OB and hospital that support vaginal birth attempts also matters.

Fact: Roughly half of babies arrive in week 40 — but very few on the exact date

  • Mostly true. About half of singleton pregnancies deliver by the end of week 40, but only around 5% arrive on the due date itself. Births spread across weeks 37–42, with the median falling in week 40. First-time mothers tend to go slightly later (often nearer 41 weeks).
  • What it means for you: don't be anxious if labour hasn't started on or before your date — that's normal, especially for a first baby. Watch for true labour signs, keep your weekly visits, and discuss induction at 40–41 weeks. The due date is an estimate, not a deadline, so keep any naming or ceremony plans flexible. For what comes next, see pregnancy week 41.

Myth: 'Going past your date means the baby is in danger'

  • Mostly false — risk rises modestly, not dramatically, until 42+ weeks. Late-term (41 weeks) and post-term (42+ weeks) pregnancies carry a slightly higher chance of stillbirth, a larger baby, meconium-stained fluid, an ageing placenta and reduced fluid. The increase is real but the absolute risk stays low, which is exactly why Indian OBs typically recommend induction by around 41 weeks rather than waiting indefinitely.
  • What it means for you: monitoring steps up — usually twice-weekly NST and BPP from 41 weeks — and induction is discussed at 40–41 weeks. Going past your date is not an emergency in itself; close monitoring catches problems early, and most late-term babies are perfectly healthy.

Fact: Comfort measures genuinely help in early labour

  • True. As you wait for or move through early labour, simple measures ease the discomfort: a warm (not hot) shower or bath to relax muscles — though skip the bath once your waters have broken; sitting and rocking on a birth ball; walking; firm back or sacral massage during contractions; a heat pad on the lower back; staying hydrated; and small, light snacks for energy.
  • Breathing helps too: slow deep breathing between contractions, lighter pattern breathing through them, and consciously relaxing every muscle in the gaps (fighting a contraction with a tense body makes the pain worse). Visualisation, music, dim light and a trusted support person all make a difference. Labour is hard work, but your body is built for it — and pain relief is there if you choose it.

Frequently asked questions

I'm 40 weeks pregnant with no signs of labour. Is something wrong?

Almost always, no. Only about 5% of babies are born on the due date, and roughly half of pregnancies are still going at the start of week 40 — first-time mothers especially often reach 41 weeks. Keep doing your daily kick counts, attend your weekly visit, and your OB will discuss a membrane sweep and induction if labour hasn't started. Go to hospital sooner if your baby's movements drop, your waters break, or you have bleeding or severe headache.

How will I know if I'm in real labour and not Braxton-Hicks?

Real labour contractions get longer, stronger and closer together and don't ease with rest or a change of position. A common guide for a first baby is the 4-1-1 rule — contractions every 4 minutes, lasting 1 minute, for 1 hour. Your waters breaking or a heavy bloody show are also signs to go in. Braxton-Hicks are irregular, don't intensify, and often settle with rest and fluids. If you're unsure, call your OB — they would rather check you than have you miss true labour.

Do eating dates really help with labour?

There is reasonable randomised-trial evidence (mostly from Iran, with some Indian studies) that eating about 5–6 dates a day from week 36–37 is linked to a more favourable cervix, shorter active labour and less need for induction. It's low-risk for women with normal blood sugar, but dates are concentrated, high-glycaemic sugar, so if you have gestational diabetes, check with your OB or dietitian before adding them.

What is a membrane sweep, and should I have one?

A membrane sweep is a quick procedure during a vaginal exam in which your OB sweeps a finger around the cervix to separate the membranes, which releases natural prostaglandins and can encourage labour to start. It's commonly offered around or after your due date to reduce the need for formal induction. It can be uncomfortable and may cause some cramping or light spotting afterwards, which is normal. It's your choice — discuss the timing with your OB.

When should my OB induce labour if I go overdue?

Most Indian OBs recommend induction by around 41 weeks, because the small rise in stillbirth and meconium-related risk after that point outweighs the benefit of waiting longer. Some offer it at 40+5 or 41+0 days, with the exact timing depending on how your cervix looks (the Bishop score) and your monitoring results. From 41 weeks you'll usually have twice-weekly NST and BPP checks until your baby is born.

My baby is moving less at 40 weeks — is that normal because there's less room?

The type of movement can change as space gets tight — more rolls and stretches than big kicks — but the amount and pattern should not drop. Reduced movement is never something to wait out. Lie on your left side after a meal or sweet drink and count movements; if you don't reach 10 in 2 hours, go to hospital that day or night for an NST. Prompt checking can prevent serious problems.
