Pregnancy Week 23: Baby Development, Symptoms & India Care Guide

• Your baby weighs around 500–550 g and measures about 28–29 cm; the lungs are entering the canalicular phase, which is why survival becomes meaningful from week 24 onwards.
• Most week-23 symptoms are second-trimester carry-overs — back pain, heartburn, leg cramps, swelling, congestion — plus the first Braxton-Hicks practice contractions for some women.
• Your ANC visit checks weight, BP, urine, fundal height (about 23 cm) and the baby's heartbeat, and sets up the next steps: the glucose test at 24–28 weeks, Tdap at 27–36 weeks, and Anti-D at 28 weeks if you are Rh-negative.
• Any vaginal bleeding, leaking fluid, more than 4–6 contractions an hour, severe headache with vision changes, or a clear drop in your baby's movements needs urgent medical review.
• Aim for about 71 g of protein a day, keep up iron, calcium and vitamin D, stay active for 150 minutes a week, and do daily pelvic-floor exercises.

Week 23 sits just below the viability threshold — the point at which a baby born early has a real chance of survival with intensive newborn (NICU) care. Your baby now measures around 28–29 cm crown-to-heel and weighs about 500–550 grams, close to a large mango. Active resuscitation at exactly 23 weeks is offered only at some top tertiary centres on a case-by-case basis, depending on the baby's weight, condition and the family's wishes; survival is roughly 25–40 per cent at the best-equipped global centres and lower at most Indian hospitals. 24 weeks is the formal threshold, and the chances rise quickly with every week after that.

What is developing this week: the skin is still wrinkled, reddish and translucent, but fat is beginning to deposit very slowly beneath it; vernix (the waxy protective coating) is thickening and fine lanugo hair covers the body; the eyebrows and eyelashes are well formed and tear ducts are appearing. The lungs are reaching the canalicular phase — the smallest airways are forming and tiny blood vessels are growing close to them, which is why babies born from week 24 onwards have a meaningful chance of breathing. Surfactant, the substance that keeps the lungs from collapsing, is being made in small amounts and rises sharply after week 28. The pancreas is developing the beta cells that make insulin, and the bone marrow has taken over most red-blood-cell production.

Movement: your baby is very active now — you may feel frequent kicks, rolls and even rhythmic hiccups, with clearer sleep-wake cycles. A partner can often feel a strong kick from the outside of the belly from around weeks 24–26.

Senses: hearing is well developed and your baby responds to sound; the eyes are still closed but sensitive to light, and the sense of touch is becoming refined.

Heart: the heart is fully formed, beating at 120–160 beats per minute and clearly visible on ultrasound.

Placenta and fluid: the placenta is mature; there is roughly 500 ml of amniotic fluid, largely made of your baby's urine plus secretions, and it is recycled continuously.

In your body: blood volume keeps expanding and your heart is working harder; the top of your uterus (fundus) now sits well above the navel at a fundal height of about 23 cm; your breasts may start producing colostrum; and the insulin resistance of pregnancy is building, which is exactly why the glucose test is timed for the coming weeks.

Week-23 symptoms mostly continue the patterns of the late second trimester. By now most women recognise their baby's movement pattern, which becomes reassuring to track.

Back pain: ongoing as your bump grows and posture shifts — pregnancy yoga, supportive footwear, a support belt and physiotherapy all help.

Heartburn and acidity: progressive as the uterus presses upward; try smaller meals, staying upright after eating and elevating your head at night, with antacids or H2-blockers/PPIs if your doctor advises.

Constipation: common — increase fluids and fibre, stay active, and use a stool softener if needed.

Skin changes: stretch marks, melasma and the linea nigra become more visible, along with itching as the skin stretches.

Leg cramps: often at night — gentle stretching before bed and adequate hydration help, with magnesium if your doctor recommends it.

Swelling: mild puffiness of feet and ankles — rest with your feet elevated and avoid standing for long stretches; sudden or severe swelling of the face and hands is different and needs review.

Breast changes: tenderness, and possibly the first drops of colostrum.

Nasal congestion, bleeding gums and vivid dreams may also continue.

Braxton-Hicks contractions: these practice contractions may begin around now — brief, painless tightening of the uterus lasting 30–60 seconds, irregular, and not building in strength or frequency, often after activity or in the evening. They are normal and ease with hydration, rest or a change of position. What is not normal is more than 4–6 tightenings an hour with cramping or back pain, which can signal preterm labour. Learn to tell Braxton-Hicks from real contractions.

Your bump is clearly visible now, whatever your build. Your doctor measures the fundal height (from the pubic bone to the top of the uterus) at each visit — it roughly matches your gestational age in centimetres, so about 23 cm this week. A difference of more than 2–3 cm from expected may prompt a growth scan to check the baby's size and the amniotic fluid. In Indian families, comments from relatives and strangers about your bump's size or shape — and predictions about the baby's sex — are common. You can graciously deflect intrusive questions; you owe no one an explanation.

Skin changes intensify: the linea nigra (the dark line down the centre of the abdomen) becomes prominent in most women, and melasma (darker patches on the cheeks, forehead and upper lip) is more noticeable on deeper Indian skin tones — it usually fades after delivery. The nipples and areolas darken further, and stretch marks may appear on the bump, breasts, thighs and hips, starting pink or red and fading to silver over months. Genetics largely decide who gets them; moisturising with coconut, almond or vitamin-E oil, or creams like Bio-Oil or Mamaearth (Rs 200–1,500), keeps skin comfortable even though the evidence that they prevent marks is limited. See caring for stretch marks and striae in pregnancy.

Comfort measures for the growing bump: a well-fitted supportive bra a size or two larger; loose, breathable clothing — many Indian women find a kurta with a drawstring waist, leggings or a comfortably draped saree easier than fitted Western wear at this stage; flat or low-heeled footwear with arch support; and a maternity support belt (Rs 500–2,500) if back or pelvic pain is significant. Sleeping on your left side is preferred from the second trimester because it improves blood flow back to the heart; a full-body or wedge pregnancy pillow (Rs 800–4,000) makes a real difference, as does a pillow between the knees and under the bump.

Sex in the second and third trimester is safe for most women with no specific contraindication (such as placenta previa, threatened or prior preterm labour, or ruptured membranes). Libido varies — some women feel more interested, others less, because of fatigue, body image or discomfort. Side-lying or partner-on-top positions ease pressure on the bump, and open communication helps. Any bleeding or significant pain afterwards should be checked. Some cultural beliefs discourage sex during pregnancy entirely; medically, this is not necessary in an uncomplicated pregnancy.

Skin care now: avoid retinoid products (Retin-A, tretinoin, isotretinoin) as they are unsafe in pregnancy; use a daily broad-spectrum SPF 30+ sunscreen, which also helps with melasma; and keep skin moisturised — coconut, almond and vitamin-E oils are all safe. Severe itching, especially of the palms and soles, needs liver-function tests to rule out obstetric cholestasis, and a harmless but itchy late-pregnancy rash called PUPPP can be managed with your doctor's help.

India's standard ANC schedule (per WHO and Ministry of Health and Family Welfare guidance) recommends visits at booking, around weeks 14–20, then weeks 24, 28, 32 and 34–36, and weekly after 36 — about 8–12 visits in all, with more if your pregnancy is higher risk (gestational diabetes, high blood pressure, anaemia, a previous preterm birth, twins, advanced maternal age, a prior caesarean, or growth or fluid concerns).

A routine visit around now covers your weight (aim for a total pregnancy gain of about 11–16 kg if your starting BMI was normal), blood pressure, a urine dipstick for protein and sugar, fundal height (about 23 cm), the baby's heartbeat by handheld Doppler, a review of your symptoms and supplements, your test results, and the plan for the next visit.

Your doctor will also set up the weeks ahead: the glucose (GTT/OGTT) screen for gestational diabetes at 24–28 weeks — read how the glucose test works and how to prepare; the Tdap vaccine; Anti-D for Rh-negative mothers; and, if you have any risk factors such as a short cervix or a previous preterm birth, closer monitoring including cervical-length scans and possibly progesterone.

Tdap vaccine: the Indian Academy of Pediatrics (IAP) and FOGSI recommend a single Tdap dose (tetanus, diphtheria, acellular pertussis) between 27 and 36 weeks — ideally 28–32 weeks for the best antibody transfer. Your antibodies cross the placenta and protect your newborn from whooping cough until the baby's own vaccines start at 6 weeks, which matters because pertussis can be life-threatening in tiny babies. Tdap is well studied and safe in pregnancy; a sore arm or mild fever is possible. It costs about Rs 500–1,200 privately (Boostrix, Adacel) and is free at government facilities. The older two-dose tetanus toxoid (TT) schedule is still used at many government centres; if you have already had TT this pregnancy, ask your doctor whether Tdap should still be given for the pertussis cover. See the full pregnancy vaccine schedule — TT, Tdap, flu and COVID.

Anti-D immunoglobulin for Rh-negative mothers is given routinely at 28 weeks to prevent Rh sensitisation that could harm future pregnancies, and again within 72 hours of delivery if the baby is Rh-positive. Rh-negative blood is found in about 5–7 per cent of Indians. It is also needed after any bleeding, trauma, amniocentesis or pregnancy loss. It costs roughly Rs 2,500–5,000 privately and is free at government tertiary hospitals and under Ayushman Bharat PMJAY; supply can be intermittent, so confirm availability in advance. Read more on Rh incompatibility and Anti-D in India.

Other tests in this window: a repeat blood count for anaemia at 24–28 weeks (and again at 32–36), a urine culture if there are symptoms, a growth scan if there is any size-dates mismatch or other concern, and for higher-risk pregnancies, cervical-length scans and — from week 28 — NST and biophysical-profile monitoring. Thyroid levels are rechecked if you are on treatment.

Government pathway: ANC is free under JSSK at all PHCs, CHCs, district hospitals and medical colleges, and PMSMA on the 9th of every month offers free specialist obstetric consultation — especially useful for high-risk monitoring. Your Mother and Child Protection (MCP) card tracks everything. Privately, expect 2–4 visits in this window at roughly Rs 500–2,500 each, often bundled into a comprehensive ANC package.

This is not about ‘eating for two’. You need only about 340 extra calories a day in the second trimester (around 450 in the third) — quality matters far more than quantity. The goal is enough protein, iron, calcium and vitamin D for your fast-growing baby.

Protein rises in importance now — about 71 g a day in India (ICMR), or roughly 1.1 g per kg of your pre-pregnancy weight. Good vegetarian sources: dal (15–18 g per cooked cup), sprouts, paneer (18–20 g per 100 g), curd, milk, soya chunks (very high), nuts and seeds, and millets like ragi, bajra and jowar. Pairings such as dal-rice, rajma-chawal, idli-sambar, khichdi, dhokla and paneer-paratha give complete protein. Non-vegetarians can add eggs (fully cooked), chicken, and small fish like sardines and mackerel for omega-3, while avoiding large predatory fish (shark, swordfish, king mackerel) for mercury.

Iron is critical — NFHS-5 found 52 per cent of pregnant Indian women are anaemic, so most need a supplement (60 mg elemental iron daily, more if anaemic). Take it with a vitamin-C source like lemon water for better absorption, and keep it away from tea, coffee and calcium. Build iron-rich foods into every meal too — see iron-rich foods for pregnancy in India.

Calcium needs are 1,000 mg a day — from dairy, ragi, sesame (til), almonds and drumstick (moringa) leaves, with a supplement if your diet falls short. Vitamin D deficiency is very common in India despite the sun, so most women supplement (commonly 60,000 IU monthly or 1,000–2,000 IU daily).

Foods to be careful with, with the evidence behind the advice: ripe (yellow) papaya is safe and nutritious — only unripe green papaya in large amounts is a theoretical concern, so the blanket ‘no papaya’ rule is overcautious; a normal serving of ripe pineapple is fine; avoid raw or undercooked meat, fish and eggs, unpasteurised dairy and raw-milk cheeses, street-vendor cut fruit and reheated leftovers; keep caffeine under 200 mg a day (about one coffee); and avoid alcohol entirely.

Cultural foods, in perspective: ghee, almonds and dates are nutrient-dense in moderation; saffron and jaggery in small culinary amounts are fine; coconut water and buttermilk (chaas) are excellent for hydration. Avoid Ayurvedic or herbal preparations without your doctor's approval, since composition and purity vary and some herbs are unsafe in pregnancy.

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; keep ORS handy in the heat or after any vomiting.

Staying active is strongly recommended unless your doctor has advised otherwise. WHO, FOGSI, ACOG and RCOG all back moderate-intensity exercise in pregnancy because it helps control weight gain, lowers the risk of gestational diabetes (by around 25–30 per cent in pooled trials) and pre-eclampsia, eases back and pelvic pain, improves mood and sleep, and supports an easier labour and recovery.

Aim for at least 150 minutes of moderate activity a week — simply 30 minutes on five days — plus light strength work 2–3 times a week and pelvic-floor exercises daily. Use the ‘talk test’: you should be able to talk but not sing.

Good choices now: brisk walking (the most accessible option in India — in a park, on a treadmill, or in a mall on very hot or high-pollution days); swimming and aqua-aerobics, which the bump-supporting buoyancy makes ideal; a recumbent stationary bike; and prenatal yoga, with props, avoiding hot/Bikram styles. Add light, well-controlled strength work, skipping the Valsalva strain and heavy overhead lifts.

Pelvic-floor (Kegel) exercises matter most now as the uterus grows heavier: tighten the muscles you would use to stop urine for 5–10 seconds, release, and repeat 10–15 times, three sets a day, sitting, standing or lying down. Done consistently through pregnancy and after birth, they lower your risk of urinary leakage and prolapse. See how to do Kegels and pelvic-floor exercises.

Modify for your shifting balance: avoid lying flat on your back for more than a few minutes after about 16–20 weeks (use a slight left tilt or side-lying instead), watch your footing as your centre of gravity moves forward, avoid extreme stretches because pregnancy hormones loosen the joints, and skip full sit-ups and unmodified planks.

Avoid throughout pregnancy: contact sports, anything with a fall risk (skiing, horse-riding, advanced cycling on Indian roads), scuba diving, high altitude without acclimatisation, and overheating from hot yoga, saunas or very hot baths.

Stop and call your doctor if you have vaginal bleeding, persistent contractions (more than 4–6 an hour before 37 weeks), leaking fluid, dizziness or fainting, chest pain, breathlessness beyond normal exertion, calf pain or swelling, or a clear drop in your baby's movements.

Practical India tips: exercise in the cool of early morning or evening in summer and hydrate hard; on high-AQI days (AQI over 200) in cities like Delhi NCR, prefer indoors; women-only classes and home-based yoga or walking remove most barriers. Push back firmly on the myth that pregnancy means complete bed rest — for the vast majority of women it does not. The late second trimester is often the best window to build a routine you can carry into the third.

Some symptoms need urgent contact with your doctor or a trip to the nearest hospital with obstetric services. Call without delay for any vaginal bleeding (which can signal a placental problem or preterm labour), severe abdominal pain especially with bleeding or contractions, a gush or trickle of fluid (possible water break), regular painful contractions before 37 weeks (more than 4–6 an hour with cramping or back pain — possible preterm labour), or signs of significant blood loss such as dizziness, a racing heart or pale, clammy skin.

A fever above 38°C suggests infection — a urinary infection is common in pregnancy and can trigger preterm labour if untreated, and other infections (dengue, typhoid, COVID, influenza, listeria) can affect both you and your baby. Do not self-medicate with random antibiotics; see a doctor.

A severe or persistent headache, especially with blurred vision or flashing spots, severe pain in the upper abdomen, marked swelling of the face and hands, or a sudden weight jump (over 1 kg in a week) are warning signs of pre-eclampsia, which becomes a real risk from week 20 onwards — get your blood pressure checked urgently. See recognising and managing pre-eclampsia in India.

Because the viability threshold is near, preterm-labour signs matter especially this week: regular painful contractions, pelvic pressure, a change in discharge (watery, mucousy or bloody) or low backache coming in waves all mean you should reach hospital immediately. If preterm delivery looks likely, antenatal corticosteroids given 24–48 hours beforehand greatly improve the baby's outcomes.

Also get reviewed for: burning or pain when passing urine with fever and backache (possible kidney infection); one-sided calf pain or swelling (possible clot); chest pain, severe breathlessness or blue lips (emergency); and severe itching of the palms and soles (possible obstetric cholestasis, needing liver tests).

A clear, persistent drop in your baby's usual movements — or no movement for several hours during an active time — should always be checked. Formal kick counting becomes a routine self-monitoring tool from week 28, explained in fetal monitoring with NST and BPP.

Mental-health emergencies count too. If you have thoughts of harming yourself, severe hopelessness, or you are seeing or hearing things that are not there, call iCall (9152987821), Vandrevala Foundation (1860-2662-345) or NIMHANS Tele-MANAS (14416), go to the nearest emergency department, and tell someone you trust.

How to get urgent care: 102 (Janani Express) is the free maternal ambulance across India, and 108 is the general emergency ambulance. Government district hospitals and medical colleges provide free 24-hour emergency obstetric and newborn care under JSSK, and major private chains run 24-hour obstetric services. Keep your doctor's number, your hospital's emergency line and your blood group saved and to hand.

Your emotional health deserves as much attention as the physical changes. Many women in the late second trimester feel a mix of anticipation, anxiety about labour and the baby's health, worries about finances, work and family dynamics, sudden ‘nesting’ urges, and mood swings from hormone shifts and broken sleep. For those with previous losses or a long journey to conceive, anxiety can persist even past the viability point. All of these feelings are valid — the cultural expectation that pregnant women must always be joyful does not match real life.

Antenatal depression and anxiety each affect roughly 15–20 per cent of pregnancies in India, and untreated maternal mental illness is linked with poorer outcomes such as preterm birth and low birth weight. The instinct to ‘tough it out’ or quietly stop medication is usually the wrong one — talk to your doctor and, where needed, a psychiatrist experienced in perinatal care. Learn to tell pregnancy anxiety from depression.

Treatment is effective and safe when chosen carefully. Sertraline is among the best-studied antidepressants in pregnancy; valproate is avoided. Therapy such as CBT works well, often without medication, and tele-therapy through platforms like Practo, YourDost and Wysa is widely available at Rs 500–3,000 a session, increasingly covered by insurance under the Mental Healthcare Act 2017. Crisis helplines: iCall (9152987821), Vandrevala Foundation (1860-2662-345), AASRA (9820466726) and NIMHANS Tele-MANAS (14416).

Reaching the viability threshold is itself an emotional milestone — relief that the baby could survive if born now, mixed with fresh worry about preterm risk, particularly for high-risk pregnancies. Indian cultural pressure to appear only grateful can make it hard to share difficult feelings, and attention often centres on the baby rather than the mother. Your wellbeing matters equally; do not let stigma about psychiatric care keep you from help, and do not assume problems will simply vanish after delivery — antenatal depression strongly predicts postnatal depression and is best treated early.

Bonding deepens now through your baby's strong movements, talking or singing to the bump, gentle touch (a partner can often feel kicks from outside between weeks 24 and 28) and listening to music together. Some women bond intensely before birth and others more afterwards — both are completely normal.

A partner's involvement shapes the whole pregnancy experience. Supportive steps: ask how she is feeling, physically and emotionally, without pressure to be cheerful; share decisions about ANC, vaccination, hospital and birth plan; attend visits where possible; learn about pregnancy and labour together; take on more of the household load as fatigue and the bump grow; and manage external pressure so that decisions rest with her and her doctor rather than with well-meaning relatives.

Partners have their own feelings too — joy mixed with anxiety about supporting her, the coming labour, finances and parenthood. Talking to other expectant partners helps, and ANC visits, NST sessions and feeling the baby kick from outside all build connection before birth. Childbirth-education classes (Lamaze, Bradley, hypnobirthing, or hospital-run sessions) welcome partners and are valuable for both.

The Indian joint family brings genuine support — cooking, company, help with older children and traditional postpartum care — alongside real challenges, such as advice that conflicts with medical guidance or pressure around ceremonies and delivery choices. What helps: agree that medical decisions rest with the mother and her doctor (with the partner as advocate), use ‘my doctor advised’ as a polite shield, set boundaries on intrusive comments, and accept genuine help while gently declining unhelpful pressure.

This is also when many start planning the baby shower — Godh Bharai in the north and west, Seemantham or Srimantham in the south, Valaikappu (the bangle ceremony) in Tamil Nadu, Shaad in Bengal, Dohale Jevan in Maharashtra — usually in the seventh or eighth month, around weeks 28–32, once preterm risk has eased. These warm traditions of blessing, gifts and the mother's favourite foods are lovely to take part in; just don't let them become an obligation that adds stress in a tiring trimester.

Practical planning helps too: confirm your maternity-leave start (the Maternity Benefit Act gives 26 weeks of paid leave for the first two children at establishments with 10+ staff), plan a work handover, and line up postpartum help (a japa maid typically costs Rs 10,000–25,000 a month). Start the birth-plan conversation early — where to deliver, who you want in the room, pain-relief preferences, and what happens if a caesarean becomes necessary.

A note on the law and on safety: under the PC-PNDT Act 1994, sex selection and disclosing the baby's sex are criminal offences — firmly resist any gender-preference pressure. If you face emotional or physical abuse, call 181 (women's helpline), 1091 (women's safety) or the NCW helpline (7827-170-170). Anything seriously affecting your wellbeing is part of your care, and your medical team should know.

Week-23 costs centre on the routine ANC visit plus any tests, vaccines or Anti-D due in this window. A private ANC visit runs about Rs 500–2,500; at government PHCs, CHCs, district hospitals and medical colleges it is free under JSSK, including tests, ultrasounds, medicines, delivery, postnatal care and the 102 ambulance.

Typical private test costs in this trimester: the glucose test (GTT/OGTT) Rs 500–1,500; a blood count Rs 200–600; urine routine and culture Rs 100–500; a growth scan Rs 1,500–3,500; a non-stress test Rs 500–1,500; and a cervical-length scan, if needed, Rs 1,500–3,000. All are free under JSSK at government tertiary centres.

Vaccines and immunoglobulin: Tdap costs about Rs 500–1,200 privately (free at government facilities), and Anti-D for Rh-negative mothers about Rs 2,500–5,000 a dose privately (free at government tertiary centres and under Ayushman Bharat PMJAY).

Ongoing supplements run about Rs 500–2,500 a month — iron, calcium, vitamin D, folic acid and, if advised, a prenatal multivitamin or DHA.

Schemes worth using: PMSMA offers free specialist consultation on the 9th of each month; JSSK provides free comprehensive maternity care at government facilities; PMMVY gives a Rs 5,000 conditional cash transfer for a first live birth; and JSY supports institutional delivery. Several states add their own schemes, such as Tamil Nadu's Dr Muthulakshmi Reddy Maternity Benefit (Rs 18,000).

Planning privately for the trimester: 2–4 ANC visits, the glucose test and labs, one or two scans/NSTs, vaccines, and Anti-D if Rh-negative. Comprehensive ANC packages at private chains often run Rs 25,000–80,000, with delivery packages separate (roughly Rs 60,000–3,00,000 for a normal birth and Rs 1,00,000–4,50,000 for a caesarean, depending on city and hospital).

Check your insurance early — maternity cover has waiting periods (often 9 months to 4 years) and per-claim sub-limits, and a pregnancy already in progress at policy start is usually excluded. Ayushman Bharat PMJAY, CGHS, ESI and state schemes (Aarogyasri, Mahatma Jyotiba Phule Jan Arogya Yojana and others) cover eligible families.

Easy-to-forget costs: transport and time off for visits, childbirth classes (Rs 3,000–15,000), a doula (Rs 5,000–30,000), maternity clothing, a breast pump, nursery setup and postpartum help (Rs 5,000–30,000 a month). Costs add up quickly in the private sector, so budget early — the JSSK plus PMMVY route cuts out-of-pocket spend substantially for those who use it.
