Key takeaways

  • Week 28 marks the official start of the third trimester. Your baby measures roughly 37-38 cm and weighs about 1.0-1.1 kg.
  • Tdap (whooping cough) vaccine is recommended between 27-36 weeks, ideally now, to protect your newborn before their own shots begin at 6 weeks.
  • If your blood group is Rh-negative, a routine dose of Anti-D immunoglobulin is given around 28 weeks to protect future pregnancies.
  • Daily kick counting starts this week. The standard reassuring count is 10 distinct movements within 2 hours.
  • ANC visits now move to every 2-3 weeks until week 36, then weekly. Many second/third-trimester tests (CBC re-check, glucose test) are scheduled in this window.
  • Any bleeding, leaking fluid, regular contractions before 37 weeks, or reduced fetal movement needs same-day medical attention.

Your baby and body at week 28

Week 28 is the formal start of the third trimester. Your baby is around 37-38 cm long (crown to heel) and weighs roughly 1.0-1.1 kg, about the size of a large eggplant (baingan).

Your baby this week:

The brain is growing fast, with the cortex starting to form its characteristic folds and grooves. The lungs are maturing and producing more surfactant, the substance that lets the lungs expand after birth. This is a big reason survival improves so much between 24 and 28 weeks. Eyes can now open and close, eyelashes are visible, and a layer of fat under the skin is making it look smoother. Iron and other nutrients are being stored in the liver and spleen, supplies that will support your baby through the first 4-6 months of life.

Movements are now strong, frequent, and follow a recognisable pattern. You may see kicks ripple across your belly, and your partner can often feel them from the outside. Hearing is mature, and the heartbeat is steady at 120-160 beats per minute. Amniotic fluid is around 800-1000 ml and will peak around weeks 34-36.

Your body this week:

Your blood volume is now 45-50% above pre-pregnancy levels, and the top of your uterus (fundus) sits roughly 28 cm above your pubic bone. The bump is prominent, your centre of gravity has shifted forward, and the diaphragm is pushed up, so you may feel breathless on exertion. Insulin resistance is more pronounced now (the reason gestational diabetes is screened in this window), and from this point your check-ups move closer together.

Common symptoms at week 28

Most week 28 symptoms carry over from late second trimester and may intensify as the bump grows. None of the following are unusual on their own:

Manage the everyday discomforts in simple ways: pregnancy yoga, supportive footwear, and a maternity support belt help back pain; smaller, frequent meals and not lying down straight after eating ease heartburn; fibre, fluids, and gentle activity help constipation; and stretching plus adequate calcium and hydration help night-time leg cramps. A pregnancy pillow and left-side sleeping make sleep more comfortable.

Paracetamol is the painkiller of choice in pregnancy; avoid NSAIDs like ibuprofen in the third trimester unless your doctor advises otherwise. Antacids and acid-reducing medicines (H2 blockers, PPIs) are used when needed for reflux, and a sitz bath helps haemorrhoids.

Body changes and skin in the Indian context

By the start of the third trimester the bump is clearly visible for everyone, whatever your build. Your doctor measures the fundal height (top of the uterus to the pubic bone) at each visit; in this window it roughly matches your gestational age in centimetres, so about 28 cm at week 28. A difference of more than 2-3 cm from expected may prompt a growth scan to check the baby's size and amniotic fluid.

Skin pigmentation often becomes more noticeable now. The linea nigra (the dark line down the centre of the abdomen) deepens, and melasma, darker patches on the cheeks, forehead, and upper lip, can be more visible on Indian skin tones. Both usually fade after delivery. Stretch marks may appear on the bump, breasts, thighs, and hips; genetics largely decides who gets them. Moisturising with coconut oil, almond oil, or a dedicated cream (Bio-Oil, Mamaearth, Palmer's, roughly Rs 200-1500) keeps skin comfortable, though evidence that any product prevents marks is limited. See caring for stretch marks for more.

A few skin-care points matter in late pregnancy: avoid retinoid creams (Retin-A, tretinoin, isotretinoin), which are unsafe in pregnancy; use a broad-spectrum SPF 30+ sunscreen daily, which also helps limit melasma; and keep skin moisturised as the bump stretches. Severe itching, especially of the palms and soles, should never be ignored, as it can signal obstetric cholestasis and needs a liver function test.

Comfort and clothing: A well-fitted, supportive bra (often 1-2 cup sizes larger now), loose kurtas or stretchy-waist leggings, and flat or low supportive footwear all help. Sleep on your left side from the second trimester onwards, as it improves blood return; a full-body or wedge pregnancy pillow (Rs 800-4000) with one pillow between the knees and one under the bump makes a real difference. Whether you choose fitted clothes that show the bump or traditional draped sarees and kurtas is entirely your comfort and your choice. Unsolicited comments about the size or shape of your bump are common; you owe no one an explanation.

Intimacy: Sex is safe in an uncomplicated pregnancy. It is best avoided if you have placenta previa, threatened or previous preterm birth, or ruptured membranes. Libido changes either way are normal, and side-lying or other positions that take pressure off the bump can help. Stop and seek review if there is bleeding or significant pain afterwards.

Your week 28 ANC visit: Tdap, Anti-D, and kick counting

Week 28 is one of the bigger antenatal visits, with several key items scheduled together. India's ANC schedule (aligned with WHO and the Ministry of Health and Family Welfare) recommends visits at booking, around weeks 14-20, 24, 28, 32, and 34-36, then weekly until delivery, usually 8-12 visits in all. From week 28 your visits move to every 2-3 weeks, and from week 36 they become weekly. Women with high-risk features such as GDM, high blood pressure, anaemia, twins, or a previous preterm birth are seen more often.

1. Tdap vaccine. The IAP and FOGSI recommend a single Tdap dose between 27 and 36 weeks (ideally 28-32 weeks). Maternal antibodies cross the placenta and protect your newborn from whooping cough (kali khansi) for the first few months, until the baby's own shots begin at 6 weeks. Pertussis can be severe or fatal in tiny babies, so this matters. Tdap is well-studied and safe in pregnancy; a sore arm or mild fever is the most you might feel. It costs about Rs 500-1200 privately (Boostrix, Adacel) and is free at government facilities. The older two-dose tetanus toxoid (TT) schedule is still used at many government centres but does not protect against whooping cough. See the full Tdap in pregnancy guide.

2. Anti-D for Rh-negative mothers. If your blood group is Rh-negative, a routine dose of Anti-D immunoglobulin is given around 28 weeks to prevent your body from reacting to your baby's blood, which could harm a future pregnancy. A second dose is given within 72 hours of delivery if the baby is Rh-positive, and after any bleeding, trauma, or procedure. Rh-negative blood is found in about 5-7% of Indians. It costs roughly Rs 2500-5000 privately and is free at government tertiary centres and under Ayushman Bharat. Supply can be intermittent, so confirm availability in advance. Full details are in our guide to Rh incompatibility and Anti-D.

3. Kick counting starts now. From week 28 you begin counting your baby's movements once a day. Lie on your left side after a meal or a sweet drink, then count distinct movements. The standard reassuring target is 10 movements within 2 hours (the 'count to 10' method); some centres use 6 in 1 hour. If you do not reach the count, have something sweet and recount; if it is still low, go to hospital for a non-stress test (see the red flags section below).

4. Routine checks and the glucose test. Every visit includes weight, blood pressure (a key warning sign for Preeclampsia in Pregnancy: Diagnosis and Care in India), a urine dipstick, fundal height, and the fetal heart rate. A CBC is usually repeated at 24-28 weeks to re-check for anaemia. The glucose tolerance test for gestational diabetes is scheduled in the 24-28 week window if not already done.

Government pathway. ANC is free under JSSK at all PHCs, CHCs, district hospitals, and medical colleges. PMSMA provides free specialist obstetric consultation on the 9th of every month, which is especially valuable for high-risk care. Your Mother and Child Protection (MCP) card tracks everything through the pregnancy. In the private sector, expect Rs 500-2500 per visit, or a comprehensive package that bundles visits, tests, and scans.

Food and nutrition: protein, iron, and what to eat

In the third trimester your baby grows quickly, so quality nutrition matters. You need only about 450 extra calories a day now, not double your intake; 'eating for two' leads to excessive weight gain. Aim instead for steady, nutrient-dense meals.

Protein needs rise to about 71 g a day in the third trimester (ICMR), roughly 20-25 g above your usual intake; see protein needs in pregnancy. Good vegetarian sources include dal (15-18 g per cooked cup), sprouts, paneer, curd, milk, soya chunks (very protein-dense), and nuts and seeds. Complete-protein meals like dal-chawal, rajma-chawal, idli-sambar, khichdi, dhokla, and paneer-paratha do the job well. Non-vegetarians can add eggs (well cooked), chicken, and small fish like sardines and mackerel, which are excellent omega-3 sources; avoid large predatory fish for mercury.

Iron demand peaks now, both for your baby's stores and your own expanding blood volume. With over half of pregnant Indian women anaemic (NFHS-5), most need supplements: 60 mg elemental iron daily routinely, more if anaemic. Take iron with a vitamin C source like lemon water, and keep it apart from tea, coffee, and calcium, which block absorption. Pair it with iron-rich Indian foods.

Calcium and vitamin D remain important: aim for 1000 mg of calcium (dairy, ragi, til, moringa leaves, almonds) and supplement vitamin D, as deficiency is very common in India even in sunny regions. Folic acid and your prenatal supplement continue through pregnancy.

Hydration: aim for 2.5-3.5 litres of fluid a day, more in the heat. Water is best, with buttermilk (chaas), coconut water, and lemon water as good additions. Use an ORS sachet (Electral, Rs 5-15) after vomiting or diarrhoea or on very hot days.

Foods to be careful with, in perspective: Ripe papaya in normal amounts is safe and nutritious; only unripe green papaya in large quantities is best avoided. Likewise, a normal serving of ripe pineapple is fine. Genuinely worth avoiding: raw or undercooked meat, fish, and eggs; unpasteurised dairy and raw-milk soft cheeses; alcohol entirely; and caffeine above ~200 mg a day (about one coffee). For street-cut fruit and reheated leftovers, food poisoning hits harder in pregnancy, so prioritise hygiene. Avoid Ayurvedic or herbal pregnancy preparations unless cleared by your doctor, as purity and ingredients vary.

Exercise and pelvic floor work at week 28

Staying active is recommended for almost all uncomplicated pregnancies. WHO, FOGSI, ACOG, and RCOG all endorse moderate activity because it helps control weight gain, lowers the risk of gestational diabetes and preeclampsia, eases back and pelvic pain, and improves mood, sleep, and recovery after birth.

Aim for about 150 minutes of moderate activity a week (roughly 30 minutes on 5 days), plus daily pelvic floor work. Use the 'talk test': at a moderate intensity you can hold a conversation but not sing. Brisk walking is the most accessible option in India; swimming is wonderfully bump-friendly and cooling; a recumbent stationary bike is comfortable; and prenatal yoga with props suits this stage well. Avoid Bikram or hot yoga.

Pelvic floor (Kegel) exercises become especially important now as the uterus presses down. Squeeze the muscles you would use to stop urine, hold for 5-10 seconds, release, and repeat 10-15 times, three times a day. Doing this through pregnancy and after birth lowers your risk of urinary leakage and prolapse later; here is the full Kegel technique.

Modify for the bump: avoid lying flat on your back for more than a few minutes after about 16-20 weeks (use a left tilt or side-lying instead), watch your balance, skip deep stretches and full sit-ups or planks, and ease off on very hot or high-pollution days. Check the AQI in cities like Delhi NCR in winter and exercise indoors when it is above 200.

Stop and call your doctor if you have vaginal bleeding, regular contractions, leaking fluid, dizziness or fainting, chest pain, severe breathlessness, a one-sided painful swollen calf, or reduced fetal movement. Push back gently against the common 'pregnancy means complete bed rest' belief, which is wrong for most women.

When to see a doctor: red flags at week 28

Some symptoms are emergencies in the third trimester. Do not wait until your next appointment; go to the nearest hospital with maternity services the same day or night. Call 102 (the free Janani Express maternal ambulance) or 108 if you need transport.

Reduced fetal movement is the single most important red flag once kick counting has begun. If you do not feel your usual movements, lie on your left side after a meal or sweet drink and count; if you do not reach 10 movements in 2 hours, go to hospital for a non-stress test, described in fetal monitoring. Reduced movement can be the first sign of a problem, and prompt review can prevent stillbirth. Do not 'wait and see' until morning.

Other warning signs are listed below. Severe itching of the palms and soles points to obstetric cholestasis and needs a liver test, while a painful, swollen, one-sided calf may signal a clot.

Mental health emergencies count too. If you have thoughts of harming yourself, feel unable to cope, or have severe anxiety, you can call iCall (9152987821), Vandrevala Foundation (1860-2662-345), AASRA (9820466726), or Tele-MANAS (14416), and go to your nearest emergency department.

Emotions, nesting, and mental wellbeing

The start of the third trimester brings labour and birth into sharper focus, and a wide mix of feelings is completely normal: excitement about meeting your baby, anxiety about delivery, sudden bursts of nesting energy, mood swings from poor sleep, and, for some, real distress. The cultural expectation that pregnant women must always be joyful simply does not match reality, and difficult emotions are valid.

Antenatal depression and anxiety each affect a meaningful share of pregnancies in India and are often under-recognised. Untreated, they are linked to poorer outcomes and a higher chance of postnatal depression, so they are worth treating, not 'toughing out'. Learn the difference between pregnancy anxiety and depression, and know that effective help exists. Cognitive behavioural therapy is highly effective without any medication considerations, and where medicine is needed, options such as sertraline are well-studied and generally safe in pregnancy; the decision is made with your doctor.

Tele-counselling is widely available in India (Practo, YourDost, Wysa, and others, roughly Rs 500-3000 a session), and the Mental Healthcare Act 2017 increasingly requires insurers to cover mental health. Crisis lines include iCall (9152987821) and Tele-MANAS (14416).

Bonding often deepens now through strong kicks, talking or singing to the baby, and your partner feeling movements from the outside. There is no single 'right' way to bond; some women feel it intensely before birth and others more afterwards, and both are normal.

Partner support and family ceremonies

Partner involvement makes a real difference in the third trimester. Helpful things a partner can do: ask how she is feeling without pressure to be cheerful, attend ANC visits where possible, take on more of the household load, and act as a buffer against well-meaning but conflicting advice from extended family. Many partners feel the baby move from the outside for the first time around weeks 24-28, which can be a powerful moment of connection.

This is a good week to enrol in a childbirth education class together. Courses usually run 6-8 sessions starting around weeks 28-32 and cover the stages of labour, breathing and pain relief, when to come to hospital, and newborn basics. Prepared parents tend to feel less anxious and report better birth experiences. It is also a sensible time to draft a birth plan and pack the early items for your hospital bag.

Godh bharai, seemantham, valaikappu, shaad and similar baby showers traditionally fall in the seventh or eighth month, around weeks 28-32, once preterm risk has eased. They vary by community, from bangle ceremonies in Tamil Nadu to elaborate feasts in Bengal, but most involve blessings, gifts, and the mother's favourite foods. Take part in what feels meaningful and let the rest go; it should not become a source of stress in a tiring trimester.

Planning ahead: confirm when your maternity leave will start (the Maternity Benefit Act provides 26 weeks of paid leave for the first two children at establishments with 10 or more employees), arrange handover at work, and plan postpartum help, whether family, a japa maid (around Rs 10,000-25,000 a month), or a doula.

Two firm boundaries matter. Pressure to reveal or select the baby's sex is illegal in India: the PC-PNDT Act makes prenatal sex determination and disclosure a criminal offence. And if you face emotional, physical, or financial abuse, help is available through the women's helpline 181, women's safety 1091, and the NCW helpline (7827-170-170). Your medical team should know about anything seriously affecting your wellbeing.

Costs and government schemes this week

Week 28 stacks a few costs together: the routine visit plus vaccination, Anti-D if needed, and any tests due. Here is a rough private-sector picture; all of it is free under JSSK at government facilities.

Government schemes worth using: JSSK covers all ANC, tests, scans, vaccines, Anti-D, delivery, NICU, and ambulance transport free at public facilities. PMSMA offers free specialist consultation on the 9th of each month. PMMVY provides a Rs 5000 cash benefit for the first live birth, and JSY gives cash assistance for institutional delivery. Several states run additional schemes (such as Tamil Nadu's Dr Muthulakshmi Reddy Maternity Benefit Scheme).

On insurance: check your employer or personal policy for maternity cover, including any waiting period and per-claim sub-limits, and confirm it is active before your due date. Ayushman Bharat PMJAY, CGHS, ESI, and state schemes (Aarogyasri, MJPJAY, and others) cover maternity care for eligible families.

Plan for the less obvious costs too: childbirth classes (Rs 3000-15000), maternity clothing, breastfeeding supplies and a pump, the nursery, and postpartum help. The JSSK and PMMVY pathway can reduce out-of-pocket spending substantially for those who use it.

Week 28 myths, corrected

Myth: The Tdap vaccine in pregnancy is dangerous for the baby

  • False. Tdap is specifically recommended in pregnancy by the IAP, FOGSI, ACOG, CDC, RCOG, and WHO between 27 and 36 weeks (ideally 28-32 weeks). Safety data from millions of women show no increased risk of miscarriage, stillbirth, birth defects, or preterm labour; the most you might feel is a sore arm or mild fever.
  • Far from harmful, it is protective. Antibodies cross the placenta in the last trimester and shield your newborn from whooping cough during their most vulnerable first weeks, before their own vaccines start at 6 weeks. Whooping cough in newborns can cause apnea, pneumonia, and death, and outbreaks still occur in India. The older two-dose TT schedule does not include this protection, which is why Tdap is increasingly preferred.

Fact: Kick counting from 28 weeks is one of the most valuable things you can do

  • True. Daily kick counting is free, needs no equipment, and helps catch early signs of fetal distress in time to act. Every baby has a unique pattern, and a change from that pattern is the warning sign, not any single 'normal number'.
  • Method: lie on your left side after a meal or a sweet drink, then count distinct movements (kicks and rolls; hiccups do not count). Ten movements within 2 hours is the standard reassuring count. If you fall short, have something sweet and recount; if it is still low, go to hospital that day or night for an NST. Track it on paper or an app. Most reduced-movement episodes turn out fine on review, but the few that do not can be addressed only if you come in promptly.

Myth: Anti-D is unnecessary if the father's blood group is unknown

  • False. An Rh-negative mother is given Anti-D whenever the baby's Rh status is unknown or known to be positive, regardless of certainty about the father. If the father's status is unknown, the baby may well be Rh-positive, so the routine 28-week dose is the safer, standard choice.
  • Why it matters: if Rh-positive blood from the baby reaches an Rh-negative mother, her body can make antibodies that, in a future pregnancy, attack a Rh-positive baby's red cells and cause haemolytic disease of the newborn, which can be severe or fatal. Anti-D at 28 weeks, again after delivery if the baby is Rh-positive, and after any bleeding or procedure, prevents this. Skipping it because the father's status is uncertain, or because you do not plan more children, is not advisable.

Fact: Childbirth education classes reduce labour anxiety

  • True. Classes (usually 6-8 sessions starting around weeks 28-32) cover the stages of labour, breathing and relaxation, pain-relief options including epidural, labour positions, when to come to hospital, and the basics of recovery, breastfeeding, and newborn care. Prepared parents tend to feel less anxious and report better birth experiences.
  • Options in India range from hospital-run courses at major chains (Rs 3000-15000) to independent educators and free online resources. For partners, attending classes together is one of the most useful ways to be involved. Popular instructors book out, so enrol early.

Frequently asked questions

How big is the baby at 28 weeks?

Around 37-38 cm from head to heel and roughly 1.0-1.1 kg, about the size of a large eggplant (baingan). The lungs and brain are maturing quickly, and movements are now strong and regular.

Why is the Tdap vaccine given at 28 weeks?

Tdap is recommended between 27 and 36 weeks (ideally 28-32) so that antibodies cross the placenta and protect your newborn from whooping cough until their own shots begin at 6 weeks. It is safe in pregnancy and is recommended by IAP, FOGSI, and WHO.

How do I count my baby's kicks?

Once a day, lie on your left side after a meal or a sweet drink and count distinct movements. The standard reassuring count is 10 movements within 2 hours. If you do not reach it, have something sweet and recount; if it is still low, go to hospital for a non-stress test.

What is Anti-D and do I need it?

Anti-D immunoglobulin is given to Rh-negative mothers around 28 weeks to stop the immune system reacting to the baby's blood, which protects future pregnancies. You need it if your blood group is Rh-negative and the baby's Rh status is unknown or positive, even if the father's group is uncertain.

How often will I have check-ups now?

From week 28 your ANC visits typically move to every 2-3 weeks until week 36, then become weekly until delivery. Women with high-risk features are seen more often, with extra monitoring as advised.

Is it safe to exercise in the third trimester?

Yes, for most uncomplicated pregnancies. Aim for about 150 minutes of moderate activity a week plus daily pelvic floor exercises, avoid lying flat on your back and high-fall-risk activities, and stop if you have bleeding, contractions, leaking fluid, dizziness, or reduced fetal movement.
