32 Weeks Pregnant

At 32 weeks pregnant, your baby measures about 42.4 cm from head to heel. Most organs are now well formed, but the lungs and brain are still maturing. From here, much of the work is laying down fat, which will help your baby keep warm after the birth. Many babies are already head down by this week, and those that aren't still have time to turn. This is also when some people have a scan to recheck a low-lying placenta. This page covers what a 32-week ultrasound is for, how big your bump should measure, how to tell if your baby is head down, what birth at 32 weeks would mean, and which symptoms need a call.

Baby development at week 32

The fetus is now practising for life outside — breathing, sucking, and swallowing. Toenails and fingernails have grown in,. Most babies have settled into a head-down position by now or will soon. The skin is becoming opaque rather than translucent. About the size of a squash.

What an ultrasound shows at 32 weeks

A 32-week scan isn't part of routine care for everyone. When one is booked, there is usually a reason. A common one is a placenta that was lying low at the 20-week scan. One NHS trust counts a placenta as low-lying if its edge is within 20 mm of the cervix, and says about 9 in 10 of these move up as the womb grows. A repeat scan, often at 32 weeks, checks whether yours has moved. It is sometimes done through the vagina. If the placenta is still low, you'll see an obstetrician and have another scan at around 36 weeks.

Other reasons for a scan now include twins, a bump that measures bigger or smaller than expected, or a condition such as pre-eclampsia. A scan at this stage can check how well your baby is growing and show which way it is lying.

Two vaccines are also timed around now. In the US, the RSV vaccine for pregnant people is given at 32 to 36 weeks, during September to January in most of the country. It helps protect your baby from severe RSV, a lung infection. The other option is an RSV antibody given to the baby after birth, and most babies don't need both. The whooping cough vaccine (Tdap) is advised at 27 to 36 weeks. Ask at your next visit which ones you still need.

Your body at 32 weeks

  • Strong movements with less room to move
  • Shortness of breath as the uterus pushes upward
  • Heartburn
  • Trouble finding a comfortable sleep position

Your belly at 32 weeks

From about 20 to 36 weeks, your bump, measured in centimetres from the pubic bone up to the top of the womb, tends to match your number of weeks. At 32 weeks, a measurement of 30 to 34 cm is in the usual range. A number outside it often has a simple cause, such as a due date that is a little off, your build, or twins. If your provider is unsure, they may send you for a scan.

The top of your womb now pushes up under your ribs, and it will reach your breastbone at around 36 weeks. With less room for your lungs and stomach, breathlessness and heartburn are common. The extra weight at the front can also change the way you walk, and some people find they start to waddle.

Tips for week 32

  • Your provider may check the baby's position from now on
  • Prop yourself with pillows to breathe and sleep easier
  • Keep noticing your baby's usual movement pattern and call at once if it changes

32 Weeks Pregnant: your questions

What trimester is 32 weeks?
Week 32 is in the third trimester, which runs from week 28 until birth. A due date is set at 40 weeks, 8 weeks from now.
How many months is 32 weeks pregnant?
32 weeks pregnant puts you in month 8 of pregnancy. Week 32 is the first week of that month, which runs to week 35. Providers count in weeks; months are approximate.
How big is the baby at 32 weeks?
At 32 weeks, the baby is about the size of a squash, roughly 42.4 cm long and around 1702 g. That is an average; healthy babies vary.
What symptoms should I not ignore at 32 weeks pregnant?
A few signs mean you should ring your maternity unit or provider right away, day or night. The first is a baby who moves less than usual, or whose usual pattern changes. Others are bleeding, fluid that gushes or trickles out, and tightenings that start to come regularly. Before 37 weeks, these can mean early labour. Pre-eclampsia also needs an urgent check. Watch for a bad headache that won't go away with painkillers, blurry vision or flashing lights, pain just under the ribs, being sick, or swelling that comes on suddenly in the face, hands or feet.
What happens if my baby is born at 32 weeks?
Most babies born at 32 weeks do well, though many need care in a neonatal unit at first. In a national French study of babies born in 2011, 98.9% of those born at 32 to 34 weeks survived to go home, and 96.8% went home without a severe health problem. The lungs and brain are still maturing, so help with breathing, feeding and keeping warm is common. If you go into labour early, doctors may offer you steroid injections, which help the baby's lungs mature, and a drip of magnesium sulphate to help protect the brain.
How do I know if my baby is head down at 32 weeks?
Your provider can usually tell by feeling your belly for the baby's head, back and bottom, and a scan can confirm it if they're not sure. You may notice clues too. If you feel kicks low down in your pelvis and one hard lump up near your ribs, the baby may be bottom first. Babies often move into position between 32 and 36 weeks, so there's no need to worry yet. Only 3 to 4% of babies born at full term are breech.
Is cramping or diarrhoea normal at 32 weeks pregnant?
Mild cramps are usually harmless if they fade with rest, a change of position, a trip to the toilet or passing wind. Loose stools are most often due to a stomach bug or food poisoning, so keep drinking fluids. Still, early labour can start this way. Period-like cramps, a dull ache low in the back, or belly cramps with or without diarrhoea can all be signs. If cramps keep coming back in a pattern, you bleed or leak fluid, or the pain lasts after 30 to 60 minutes of rest, ring for advice at once.
Can I fly at 32 weeks pregnant?
Usually, yes, if your pregnancy is healthy, but check first. In the US, most airlines allow domestic flights until about 36 weeks, and international cut-offs are often earlier. After 28 weeks, an airline may ask for a letter from your provider confirming your due date. The NHS notes that labour is more likely after 37 weeks, or around 32 weeks if you're carrying twins. On the plane, wear your seat belt low, under your bump, drink water and walk around often to lower the risk of blood clots.
