Third trimester

41 weeks pregnant

At 41 weeks 0 days to 41 weeks 6 days, your pregnancy is late term by ACOG's definition. Labor usually starts on its own before 42 weeks, but some risks begin to rise slowly from 41 weeks. Please make sure you have talked with your midwife or doctor about monitoring and induction, so you can decide on a plan together.

This page covers 41 weeks 0 days to 41 weeks 6 days (41+0 to 41+6), counted from the first day of the last period. Check how far along you are

At this stage, size varies widely between healthy babies. Your care team checks growth directly rather than against a chart.

How your baby is developing

  • Your baby's fastest period of growth is over, and they should be mature enough to manage outside the womb without help.1
  • Babies born after their due date often have red, dry, peeling skin, because much of the protective vernix has gone. The top layer usually peels off by itself within a few days, and moisturizing it can make it worse.1
  • As pregnancy goes past the due date, the placenta may not work as well as before, which can reduce the oxygen and nutrients reaching your baby. This is one reason your care team will want to check on your baby now.2
  • Your baby should keep moving in their usual pattern right up to and during labor.3

Changes you may notice

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

  • Feeling frustrated or impatient is common at this stage. Braxton Hicks contractions and swollen hands and feet may continue.1
  • If your baby's movements slow down, stop or change from their usual pattern, call your midwife or maternity unit straight away. Do not wait for your next appointment or until the morning.3
  • Signs that labor may be starting include contractions, a show, backache, an urge to go to the toilet and your waters breaking. Call urgently if your waters break, you have vaginal bleeding, or your baby is moving less than usual.4

Care around this week

  • UK: a 41-week appointment is part of the routine schedule, and induction will be offered if labor hasn't started by 41 weeks. NICE guidance says to explain that some risks may increase from 41 weeks 0 days, including a higher chance of cesarean birth, of the baby needing neonatal intensive care, and of stillbirth and newborn death, and that induction from 41 weeks may reduce these risks. You'll also be asked to think about how induction might affect your birth experience. You may be offered a membrane sweep first.1,5,6,7
  • US: MedlinePlus says that at 41 weeks your provider will usually check on your baby with tests such as a non-stress test and a biophysical profile (an ultrasound check). If the results are reassuring, your provider may wait for labor to start. Between 41 and 42 weeks, your provider will likely want to induce labor.2
  • Induction is your choice, and your care team should explain why they are suggesting it. It usually starts in hospital with hormones placed in the vagina or taken as tablets, or a device such as a small balloon to help open the cervix. Your waters may be broken and a hormone drip may be used. Induced labor is usually more painful than labor that starts on its own, and assisted birth with forceps or ventouse is more likely.6

Questions to ask your provider

  • What monitoring do you recommend for my baby now, and how often?
  • When could induction happen, and what method would you start with?
  • What are the benefits and risks of induction compared with waiting, for me?
  • If I decide to wait, how often will we review the plan?
  • Who should I call if something changes before my next appointment?
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.8,9,10,11

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.10,12
  • 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.4,10,11,13
  • 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.3,10
  • 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.8,10,11
  • Sudden swelling of your face, hands or feet, or swelling, redness or pain in a leg.8,10,11
  • Belly pain that is severe or does not go away after resting, or pain just below the ribs.8,10,14
  • Regular tightenings or contractions, period-type pains, or backache that is unusual for you before 37 weeks, which can be signs of preterm labor.13,14
  • A fever of 100.4°F (38°C) or higher, or feeling hot, cold or shivery.10,11,13
  • Shortness of breath that comes on suddenly or happens when you lie flat, chest pain, a racing or pounding heart, or dizziness or fainting.10,11
  • Very itchy skin, especially on the palms of your hands or soles of your feet, or itching that is worse at night.15
  • 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.10,16
  • Thoughts of harming yourself or your baby. Get help right away, and call 911 or 999 if you think you might act on them.10,17

Questions about 41 weeks

Is it safe to go past 41 weeks?

NHS information says the risks are still very small but start to increase from 41 weeks. That's why your midwife or doctor will talk with you about extra monitoring or induction now.1,7

Can I say no to induction?

Yes, it's your choice. If you decide not to be induced, your care team should discuss your other options, offer you the chance to revisit the decision at each review, and, from 42 weeks, offer extra monitoring of your baby.6,7

How common is it to still be pregnant at 41 weeks?

In NHS data from 2019 to 2020, about 1 in 6 labors that started on their own began between 41 weeks 0 days and 41 weeks 6 days. By the end of that week, 99% of them had started.7
