Week 29 of pregnancy: Gaining Fast
Your baby is growing fast. What to do straight away if movements slow or change, and why breathlessness is so common now.
Last updated 28 September 2026
What's happening this week?
Your baby is in a steady growth phase, and with less space the kicks may feel sharper and more like jabs. This week's key message is about movements: if your baby is moving less, moving differently or you cannot feel them, contact your maternity unit straight away, the same day, even at night. Do not wait until the next day and do not rely on a home heartbeat monitor. For you, breathlessness is becoming common as the uterus pushes upwards.
Baby's development
Your baby is now growing quickly, at roughly 100 to 150 g a week around 28 to 30 weeks. The rate keeps rising towards a peak of about 200 to 220 g a week at around 35 weeks, before slowing a little near term. Much of this gain is fat, which gradually fills out the limbs and face, so the body looks less lean week by week.
The bones are fully formed but still soft and flexible, and they will keep hardening over the coming weeks. Your baby also keeps practising breathing-like movements and swallowing amniotic fluid, and most of that fluid is now your baby's own urine, which is one reason fluid levels are checked on later scans.
Space is getting tighter, so movements change in character: fewer big somersaults, more jabs, pushes and rolls that you may see ripple across your bump. What should not change is how often your baby moves. Movements do not slow down towards the end of pregnancy, and they continue right up to and during labour. A baby who is moving less than usual may need checking, which is why a change in movements is always treated as urgent.

Week 29
Gestational age
Measured head to heel, your baby is usually about 38 to 39 cm, and ultrasound estimates at 29 weeks commonly fall around 1.2 to 1.5 kg. The 1,150 g shown is just below that range; many healthy Indian babies track below Western medians. What matters more than any one number is that growth continues steadily from scan to scan.
Your body this week
Your uterus now presses up against the diaphragm, the muscle under your lungs, leaving them less room to expand. At the same time progesterone makes you breathe more deeply. Many women feel breathless climbing stairs or talking while walking. This is common and usually harmless, but breathlessness that comes on suddenly, happens at rest or comes with chest pain is not.
The bump also presses on your bladder, so toilet trips increase again, and heartburn may be worse after large meals. Your heart is still working harder as blood volume rises towards its peak. Braxton Hicks tightenings may come a little more often, and your ankles may swell by evening. Neither should be painful or sudden; if they are, get checked.
It is natural to feel more tuned in to your baby now, and some people start to worry about movements. Knowing exactly what to do if something feels different can make that worry easier to carry.
Symptoms you may notice
Every pregnancy is different - you may have some, all or none of these.
- Breathlessness
- Sit or stand upright, slow your pace and give yourself time on stairs. Extra pillows at night may help, while still lying on your side. Seek urgent help for sudden breathlessness, breathlessness at rest, chest pain or coughing up blood.
- Sharp jabs and kicks
- Kicks may now be strong enough to wake you or be seen from outside. The type of movement changes as space runs out, but the amount should not fall.
- Needing to pass urine often
- Pressure on the bladder is the usual cause. Burning, stinging, urgency or cloudy urine suggests an infection and needs checking the same day.
- Heartburn
- Large meals press on an already crowded stomach, so eat little and often and stay upright for a while after eating.
- Tiredness
- Carrying extra weight and broken nights take their toll. Short rests during the day help; mention exhaustion that feels out of proportion.
Medical care and tests
Assessment for reduced movements
Only if neededAny time, day or night
If you report reduced or changed movements, the maternity unit will want to see you promptly. They will usually check you, listen to or record your baby's heartbeat, and may arrange further tests if needed. Going in is never a waste of anyone's time, and you should go again whenever it happens.
Growth scan with Doppler
Commonly offeredAround 28–34 weeks in Indian private care
Many private hospitals in India offer a third-trimester scan that estimates the baby's size, the amount of fluid and placental blood flow, even in low-risk pregnancies. This is common practice rather than national guidance; the UK does not offer routine scans after 28 weeks in uncomplicated pregnancies, and WHO does not recommend routine Doppler.
Regular antenatal checks
RoutineEvery 2–4 weeks, depending on your provider
Blood pressure and urine are checked at each visit and your fundal height is measured to track growth. Government facilities in India also offer free second- and third-trimester check-ups on the 9th of each month under PMSMA.
Your doctor may give you specific instructions about watching movements. Follow them, and call whenever you are unsure.
Nutrition this week
- Protein needs are higher in the second and third trimesters, and this growth phase is a good moment to check you are getting enough. Try to include a protein food at every meal and in one or two snacks.
- Vegetarian options include dal, rajma, chana, soya chunks, paneer, dahi, milk, besan chilla and cooked or steamed sprouts. Combining a pulse with a cereal, as in dal-chawal or rajma-roti, makes a good everyday plate.
- If you eat eggs, fish or chicken, they are easy protein boosts. Cook eggs until firm, and avoid high-mercury fish such as shark and swordfish.
- If your appetite is small, spread protein across mini-meals: a handful of roasted chana, a glass of milk or a bowl of dahi between meals adds up.
Movement and exercise
- Keep activity at a level where you can still talk, and slow down when you feel breathless. Swimming can feel easier than walking because the water supports your weight.
- Walks, gentle swims and prenatal yoga are still suitable. During breathing practice, sit upright with your shoulders relaxed and breathe out slowly.
- If you notice reduced movements, do not wait to see whether a snack, a cold drink or lying down gets your baby moving. Call the maternity unit.
Things to keep in mind
- You know your baby's pattern best. If movements feel reduced, different or have stopped, contact the maternity unit or labour ward immediately, day or night, rather than waiting for your next appointment.
- Do not use a home Doppler or phone app to reassure yourself. Hearing a heartbeat does not mean the baby is well, and it can delay getting checked.
- There is no set number of kicks that is normal. Some doctors in India suggest a daily kick count; if yours has, follow their instructions, and still call if you notice any change.
- A kick counter can help you note your baby's usual pattern, but it is not a substitute for calling when something feels different.
When to contact your doctor

- Itching of the palms or soles.
- Sudden puffiness in the face, hands or feet, or a headache that lingers.

Frequently asked questions
What should I do if my baby is moving less?
Contact your maternity unit or labour ward straight away, even in the middle of the night. Do not wait until the next day, and do not try to check at home with a Doppler or app. The team will check you and your baby's heartbeat. Usually all is well, but reduced movements can sometimes be a sign that a baby is unwell, so it is always worth being seen.
Do babies move less as they run out of room?
No. The type of movement changes as space gets tighter, with more rolls and pushes and fewer big kicks, but your baby should keep moving as often as usual. Movements continue up to and during labour, so a drop in movements should never be put down to lack of space.
Should I use a kick counter?
UK guidance does not recommend counting to a fixed number, because there is no single normal number of kicks. Some doctors in India suggest a daily count; if yours does, follow their advice. A kick counter can help you notice your baby's usual pattern, but if movements seem different, call the maternity unit rather than finishing a count.
