Third trimester

32 weeks pregnant

At 32 weeks your baby is fully formed and mainly needs to gain weight, while the lungs and brain keep maturing. Most babies are head down by now. In the US, the maternal RSV vaccine window opens this week if it falls during RSV season.

About the size of a spaghetti squash

Typical estimated weight 1.95 kg (4 lb 5 oz) at 32+0, about 2.13 kg (4 lb 11 oz) by 32+6. This is the 50th centile; healthy babies commonly vary by about 12.7% either way.1

A reference value, not a measurement of your baby.

How your baby is developing

  • Your baby is fully formed. The main job from here is gaining weight.2
  • Apart from the lungs and brain, most organs are ready for birth, and the skin is no longer see-through.3
  • Fat stores keep building over the coming month. This fat helps your baby regulate their temperature after birth.2
  • Most babies are lying head down by now, which is called a cephalic presentation. If yours is not, there is still time to turn.2
  • Rhythmic breathing movements continue, and your baby's body keeps storing iron, calcium and phosphorus.4

Changes you may notice

Everyone’s experience is different. You may notice some of these, or none.

  • Your growing bump may change the way you walk as your body adjusts to the extra weight in front.2
  • Tiredness is common, so rest when you can.2
  • There is less room in the uterus, but your baby's movements should continue at the same rate. If they slow down, change or stop, contact your provider or maternity unit straight away, even at night. You do not need to count kicks.2,5
  • Pelvic pain, heartburn, constipation, leg cramps and swelling are other common symptoms. Get medical advice about any vaginal bleeding.2

Care around this week

  • US: the maternal RSV vaccine (Abrysvo) is recommended at 32 to 36 weeks if those weeks fall during September through January in most of the country. Protection takes about 2 weeks to develop and pass to your baby, and lasts about 6 months after birth. If you do not get it, an RSV antibody is recommended for your baby instead; most babies do not need both. UK: the RSV vaccine is offered from around 28 weeks and can be given up until labor.6,7
  • US: Tdap is still recommended if you have not had it, during weeks 27 through 36. UK: the whooping cough vaccine is best given before 32 weeks, but if you missed it you can still have it later.7,8
  • Newborn vitamin K is often discussed before birth. In the UK it is offered for all babies within 24 hours of birth, usually as an injection into the thigh, to help blood clot and prevent a rare bleeding condition. You can ask about the oral form or decline it.2

Questions to ask your provider

  • Is my baby head down, and what happens if they are not by 36 weeks?
  • Should I get the RSV vaccine now, or will my baby be offered an RSV antibody after birth?
  • What will be offered to my baby right after birth, such as vitamin K?
  • If I have a cesarean, how long would I likely stay in the hospital?
When to contact your provider straight away

Call 911 (US) or 999 (UK) in an emergency, such as heavy bleeding or bleeding with severe pain, a seizure, chest pain, or severe trouble breathing.9,10,11,12

These symptoms are not always serious, but each one needs prompt advice from your provider, midwife or maternity unit (or NHS 111 in the UK if you cannot reach them) rather than waiting for your next appointment, and it helps to tell them you are pregnant.

  • Vaginal bleeding or spotting at any stage of pregnancy. Call 911 or 999 if the bleeding is heavy or comes with severe belly pain, shoulder pain, or feeling faint or dizzy.11,13
  • Fluid leaking or gushing from your vagina, or discharge that is unusual for you. Get checked straight away if the fluid is greenish, colored or smells bad.11,12,14,15
  • Your baby moving less than usual, not moving, or a change in their usual pattern of movements. Call immediately, even in the middle of the night, and do not use a home Doppler to check yourself.5,11
  • A severe headache that does not go away with simple painkillers or gets worse, or sudden changes in your vision such as blurring or seeing flashing lights.9,11,12
  • Sudden swelling of your face, hands or feet, or swelling, redness or pain in a leg.9,11,12
  • Belly pain that is severe or does not go away after resting, or pain just below the ribs.9,11,16
  • Regular tightenings or contractions, period-type pains, or backache that is unusual for you before 37 weeks, which can be signs of preterm labor.15,16
  • A fever of 100.4°F (38°C) or higher, or feeling hot, cold or shivery.11,12,15
  • Shortness of breath that comes on suddenly or happens when you lie flat, chest pain, a racing or pounding heart, or dizziness or fainting.11,12
  • Very itchy skin, especially on the palms of your hands or soles of your feet, or itching that is worse at night.17
  • Being sick so often that you cannot keep food or drink down, or signs of dehydration such as dark urine, peeing very little, or feeling dizzy.11,18
  • Thoughts of harming yourself or your baby. Get help right away, and call 911 or 999 if you think you might act on them.11,19

Questions about 32 weeks

Can I get the RSV vaccine at 32 weeks pregnant?

In the US, the maternal RSV vaccine is recommended at 32 to 36 weeks during September through January in most of the country. If you do not get it, CDC recommends an RSV antibody for your baby instead. In the UK, the vaccine is offered from 28 weeks.6,7

Do I need the RSV vaccine again if I had it in a previous pregnancy?

CDC does not currently recommend another dose in a later pregnancy. Instead, your baby should receive a long-acting RSV antibody after birth.6

Should my baby's movements slow down at 32 weeks because there is less room?

No. Space is tighter, but movements should continue at the same rate right up to and during labor. If they slow down, change or stop, contact your provider or maternity unit straight away.2,5

What if my baby is not head down at 32 weeks?

There is still time for your baby to turn. If they are not head down by about 36 weeks, your doctor or midwife may suggest ways to help them turn.2
