32 weeks pregnant.

The baby practices breathing motions — pulling amniotic fluid in and out. Lungs are nearly ready for the outside world.

The short answer: Looks like a small newborn. Skin is smooth, vernix coats it, and the baby is plumping up quickly.

What may be changing in your body

Heartburn, swelling, and shortness of breath peak. Sleep may improve briefly as the baby drops lower in the pelvis closer to birth.

Heartburn at its peak

The stomach has minimal room now, so reflux flares even with small meals. Eating earlier in the evening and sleeping propped up on pillows are the highest-impact fixes.

Shooting pains into the groin

As the baby settles lower, pressure on pelvic nerves causes sharp electric twinges — an early taste of what is nicknamed lightning crotch. Startling but harmless.

Fatigue with poor sleep

Broken nights and a heavy bump create a genuine energy deficit. Treat rest as a task on the list, not a reward for finishing it.

Swollen fingers

Rings may feel tight by afternoon. Take them off before they get stuck; sudden hand or face swelling remains a same-day call to your midwife or doctor.

Clumsy balance

Your centre of gravity is at its most forward. Hold rails on stairs, avoid ladders and step stools, and let others reach the high shelves.

When to call

Regular painful tightenings, bleeding, fluid leaking, severe headache or vision changes, or any reduction in your baby's movements: contact your maternity unit immediately.

Your week 32 checklist

  • Confirm your whooping cough vaccine was done — week 32 is the end of the ideal window, though later is still worthwhile.
  • Finalise your birth plan and give copies to your birth partner and your notes.
  • Buy any remaining hospital bag items — packing itself comes around week 35.
  • Arrange for the car seat to arrive and schedule time to practise fitting it.

A useful partner move this week

Take the car seat out of the box this week and do a full practice install — the straps and bases humble everyone on the first try, and you do not want your first attempt in a hospital car park. Then pack your own small bag: snacks, charger, change of clothes, coins for parking.

What comes next

Group B Strep screening is usually offered around weeks 35–37 — a simple swab to guide labor antibiotics if needed.

Common questions

When should I worry about shortness of breath in late pregnancy?

Gradual breathlessness on exertion that eases with rest is a normal mechanical effect of the uterus crowding your lungs. Seek urgent medical help if breathlessness comes on suddenly, occurs at rest, or is accompanied by chest pain, a racing heartbeat, coughing blood, or one-sided leg swelling — these need same-day assessment. When unsure, call your maternity unit and describe it; that is what they are there for.

When should I pack my hospital bag?

Aim to have it fully packed by around week 35, since a meaningful share of babies arrive before their due date. A practical approach: gather items from week 30, pack properly at 35, and keep the bag by the door or in the car from 37. Pack for the baby and for yourself, and include the boring winners — phone charger, snacks, lip balm, and your maternity notes.

What should actually go in a birth plan?

The most useful birth plans are short — one page covering pain relief preferences, who your birth partner is, feelings about interventions, skin-to-skin and feeding wishes, and anything staff should know about you. Think of it as preferences, not a script; labour often improvises, and flexibility protects your experience. Discuss it with your midwife around now so nothing in it comes as a surprise on the day.

How many months is 32 weeks pregnant?

Pregnancy months do not divide evenly into weeks, so clinicians date pregnancy in weeks. At 32 weeks, you are in trimester three.
