32 weeks pregnant

How big is your baby at 32 weeks?

About the length of a bunch of celery — around 42.4 cm (16.7 in) head to heel, according to the NHS, weighing roughly 1,901 g (4 lb 3 oz).

The NHS puts the next four weeks in plain numbers: you will gain around 450 g a week, and your baby around 1 kg of fat. That is what lets a newborn hold its own temperature.

A note on the numbers: from week 20 the NHS measures head to heel, not head to bottom. Weights here are the median of the WHO fetal growth charts — half of babies weigh more, half less, and a scan estimate can be out by 10 to 15 per cent either way. A number below the median is not a diagnosis.

What's developing this week

Your baby is, as the NHS puts it, perfectly formed but needs to put on weight. Most babies are head down by now — cephalic presentation. If yours is not, there is still time; if they are breech at around 36 weeks, your team may offer ways to encourage them to turn.

Do babies move less at the end of pregnancy?

No. This is the most dangerous myth in the third trimester, and week 32 is where it takes hold.

Movements increase until about 32 weeks and then stay roughly the same. Tommy's states it flatly: it is not true that babies move less towards the end. The NHS says the same on its week 32 page — as your baby gets bigger there is less space, but you should still feel movements at the same rate until you give birth, and during labour too. The type of movement changes as the room runs out, from sweeping kicks to rolls and presses. The rate should not.

There is still no number to hit. The NHS is explicit that you do not need to count kicks; what matters is your baby's usual pattern. The RCOG says there is not enough evidence to recommend routine movement charts. In the US, ACOG describes kick counting as something a clinician may ask you to do at home after you have already noticed reduced movement, using their method and their threshold. If yours has given you one, follow it — it describes a pattern, it is not a pass mark, and our kick counter works the same way.

Reduced movements do not cause stillbirth, but they can signal that something is wrong: Tommy's notes that in around half of stillbirths the mother had noticed reduced movements first. If the pattern changes or stops, call your maternity unit immediately.

What you might feel

Heavier, hotter and more breathless. Braxton Hicks tightenings are common, and heartburn, backache, pelvic pressure and swollen feet are all ordinary now. Sleep on your side rather than your back — NHS guidance, echoed by RANZCOG, is that side sleeping is safer from 28 weeks.

Is 32 weeks pregnant 7 months or 8 months?

Week 32 is the first week of month 8. Eight weeks to go.

There is no official weeks-to-months map. A calendar month averages about 4.3 weeks, not 4, so 40 weeks is a little over nine months, and two apps can disagree. The most widely used mapping:

• Month 1 — weeks 1 to 4
• Month 2 — weeks 5 to 8
• Month 3 — weeks 9 to 13
• Month 4 — weeks 14 to 17
• Month 5 — weeks 18 to 22
• Month 6 — weeks 23 to 27
• Month 7 — weeks 28 to 31
• Month 8 — weeks 32 to 35
• Month 9 — weeks 36 to 40

Your maternity team will not use months. Everything is booked by week and day — "32 weeks and 3 days" — because a few days change what is offered.

What's happening at your appointments around now

No routine UK appointment falls at 32 weeks; the next is 34. But two vaccine windows turn over this week.

• UK whooping cough closes. The NHS asks for the vaccine before 32 weeks so antibodies have time to cross the placenta, and says plainly that later is not ideal because your baby is less likely to get protection from you. If you have not had it, chase it this week — late still beats never.
• US maternal RSV opens. ACOG recommends the RSVpreF vaccine between 32 0/7 and 36 6/7 weeks, seasonally. The NHS offers RSV vaccination from 28 weeks. Same vaccine, different weeks — follow the schedule of the country you are giving birth in.

RANZCOG's pertussis window also closes around now, and if you are RhD negative in Australia or New Zealand your second anti-D dose is due at around 34 weeks. ACOG puts the usual start of extra fetal monitoring at 32 to 34 weeks for pregnancies that need it.

Is it safe to fly at 32 weeks pregnant?

With one baby and a straightforward pregnancy, the RCOG says the safest time to fly is before 37 weeks, so you are inside it — but you need an airline letter, and ACOG regards travel after 28 weeks as riskier rather than unsafe. With twins, 32 weeks is the line: the RCOG names before 32 weeks as the safest time to fly with an uncomplicated twin pregnancy, and most airlines set their cut-off at the same point.

Keep two things apart. The medical position is the RCOG's: the safest time to fly is before 37 weeks with one baby and before 32 weeks with uncomplicated twins, because from those points labour becomes likely. The airline position is a commercial rule — most carriers refuse you after 37 weeks, some set an earlier limit, and from 28 weeks most want a letter from your midwife or doctor, which the NHS warns can cost money and take weeks. An airline rule is not medical advice.

The risk that is real: blood clots

ACOG puts it plainly: any travel of four hours or more — car, train, bus or plane — doubles DVT risk, and pregnancy adds to that. Under four hours the RCOG says you are unlikely to need special measures. Over four hours:

• Loose clothing, an aisle seat, regular walks about the cabin
• In-seat exercises roughly every 30 minutes, and water steadily
• Graduated compression stockings sized for you by a midwife or doctor — ACOG warns that stockings which are too tight or worn wrongly increase the risk instead

Practical points

• Take your maternity notes in hand luggage, not the hold.
• Check what maternity and neonatal care exists at your destination, and carry your maternity notes.
• Tell your insurer you are pregnant. The NHS says cover should include care in labour, premature birth and the cost of changing your return date.
• Travel to Zika areas is not recommended; some travel vaccines and anti-malarials are unsuitable.

When to call your midwife or doctor

Maternity units are staffed 24 hours a day, and away from home you can walk into any of them.

Get emergency help now

Call your local emergency number (999 in the UK and Ireland, 911 in the US and Canada, 000 in Australia, 111 in New Zealand) or go to an emergency department if you have:

• Heavy vaginal bleeding, or bleeding with severe abdominal pain
• Abdominal pain you cannot concentrate through
• Fainting or collapse, chest pain, or sudden breathlessness
• A severe headache painkillers do not touch, blurred vision or flashing lights, pain below your ribs, vomiting, or sudden swelling of your face, hands or feet — NHS and ACOG both list these as pre-eclampsia symptoms needing immediate assessment
• Pain, swelling or heat in one calf or thigh, which can be a DVT

Call your midwife or maternity unit today, whatever the hour

• Any reduction, weakening or change in your baby's usual pattern of movements. Call immediately, not in the morning, and do not use a home doppler — hearing a heartbeat does not mean your baby is well
• Regular tightenings, period-type pains, or backache that is not usual for you — the NHS list for possible premature labour, meaning labour before 37 weeks, which affects about 8 in every 100 babies
• A gush or a trickle of fluid, which could be your waters breaking
• Any vaginal bleeding, however light
• Itching without a rash, especially at night or on your palms and soles — it can be intrahepatic cholestasis of pregnancy
• A temperature, feeling generally unwell, or burning when you pee

You do not need to be certain something is wrong. That is what the number is for.
