36 weeks pregnant: position checks and the ways babies are born
The appointment this week matters more than it feels. Here is what will be checked, and what your options are if your baby is not head-down.
Updated October 13, 2026 · sources checked October 13, 2026
In short
At 36 weeks your baby is about 47 cm from head to heel (NHS) and the lungs are probably mature enough to breathe without help. Your midwife or doctor will check your baby's position; if your baby is bottom-down, you may be offered a turn (ECV). The one thing to do this week: go to your 36-week appointment, even if getting there feels like a marathon.
Where you are at 36 weeks
You are at the end of month 9 in Cleveland Clinic's grouping and four weeks from your estimated due date. From next week, 37 weeks, a birth is called early term, not premature. Your pregnancy week calculator gives you the exact day count.
Your baby this week
The NHS gives about 47.4 cm from head to heel, comparing it to a romaine lettuce, and says the lungs are probably mature enough to breathe outside the womb without help. Your baby can also suck and digest milk now.
Cleveland Clinic says the fine body hair called lanugo is being shed and there is hair on the head. By the end of this ninth month it gives an average length of 17 to 19 inches and a weight of 6 to 7 pounds; your own baby may be smaller or bigger, which is why your bump is measured at each visit.
Your body and common symptoms
- Leaks when you laugh or cough. The NHS links this to the pelvic floor relaxing before birth. A Cochrane review found that pelvic floor muscle training in pregnancy probably lowers the chance of leaking in late pregnancy for people who were not leaking before. Squeeze and lift as if stopping a pee, hold, release, several times a day.
- Heaviness low down. If your baby has engaged, you may breathe more easily but feel pressure in your pelvis. The NHS adds that engagement does not mean labour is near; it could still be weeks away.
- Everything is an effort. That is normal at 36 weeks. Accept lifts, deliveries and help.
Is this normal? When to call
Call your midwife or maternity unit straight away if your baby moves less or the pattern changes, if your waters break, you bleed, you have regular painful contractions, a severe headache, vision changes, pain under the ribs or sudden swelling. Before 37 weeks, any sign of labour needs a call. UK: maternity unit, NHS 111 if you cannot reach them, 999 in an emergency. US: OB-GYN or midwife, 911 in an emergency.
Appointments and tests around 36 weeks
| United States | United Kingdom (England) | |
|---|---|---|
| Routine check | Visits move from every two weeks to weekly as your due date nears (Cleveland Clinic) | 36-week appointment: the midwife feels your bump for the baby's position, measures it, checks blood pressure and urine, asks about movements and your mental health (NHS) |
| Group B strep | Vaginal and rectal swab between 36 and 38 weeks (ACOG) | Not routinely offered (NHS) |
| Baby head-up | Your OB-GYN will discuss options | ECV may be offered; it works around half the time (NHS) |
| Vaccines | Week 36 is the last week of the CDC windows for Tdap (27 to 36) and the RSV vaccine (32 to 36, September to January) | RSV vaccine still possible up until labour if missed |
The ways babies are born (England, NHS figures)
- Vaginal birth: around 6 in 10 births. Labour has three stages: the cervix opening to about 10 cm (often 6 to 12 hours), pushing and birth, then the placenta.
- Caesarean: nearly 3 in 10 babies, planned or emergency. The operation takes 40 to 50 minutes and you may stay in hospital a few days.
- Assisted birth: just over 1 in 10, with ventouse (suction cup) or forceps.
- After a previous caesarean: the NHS says a vaginal birth is often possible, depending on why you needed the caesarean. Ask about the pros and cons for you.
Every route is a good birth when you and your baby are safe. Our guide to caesarean birth explains what to expect if you need one.

For your partner
Practise the car seat, do one dry run to the hospital or birth centre, and take on the pelvic floor reminder with kindness, not commentary.

Questions parents ask
What happens if my baby is breech at 36 weeks?
The NHS says you may be offered external cephalic version (ECV), where a doctor or midwife gently uses their hands on your bump to encourage the baby to turn; it works around half the time. Some babies turn on their own later. Your team will talk you through the options for birth.
When is the group B strep test?
In the US, ACOG says the swab from the vagina and rectum is done between 36 and 38 weeks. In the UK the NHS does not test routinely, because GBS is very common and a test cannot predict which babies will be affected; tell your midwife if you have had GBS before.
Is it normal to leak pee when I laugh at 36 weeks?
Yes, it is common. The NHS explains that the pelvic floor muscles around the bladder relax as your body prepares for birth. Maternity pads and pelvic floor exercises help.
