When to Go to Hospital in Labour: A Clear Guide for First and Subsequent Births

One of the most common questions in late pregnancy is knowing the right moment to leave for hospital. Go too early and you may be assessed in early labour and sent home. Wait too long and — particularly for second or subsequent births — you may find yourself further along than expected. Getting the timing right matters, but so does understanding the signs that mean you should not wait at all.

This guide covers the standard NHS timing guidance for first and subsequent pregnancies, what to do if your waters break, the home birth option, and a clear list of situations where you should go immediately regardless of contraction frequency.

⚠️ MEDICAL DISCLAIMER

This article is educational information only. It is NOT a substitute for professional medical advice, diagnosis, or treatment.

Always consult your pediatrician or healthcare provider before making any medical decisions for your baby or child. Every baby is unique, and professional medical guidance is essential.

In case of emergency, call 911 or your local emergency number.

The Standard Guidance for First-Time Mothers

For uncomplicated first pregnancies, the NHS and NICE recommend calling your maternity unit when contractions are:

• Regular — following a consistent pattern rather than irregular Braxton Hicks
• Approximately 5 minutes apart (measured from the start of one contraction to the start of the next)
• Lasting around 60 seconds each
• Sustained for at least an hour

This is broadly consistent with the widely cited 5-1-1 rule (5 minutes apart, 1 minute long, for 1 hour). The maternity triage team will ask you to describe the pattern, how long it has been going on, whether there is any bleeding, whether your waters have broken, and how the baby is moving.

You are not expected to have perfect data. Describe what you have noticed and let the team guide you. They may ask you to continue monitoring at home for another hour, or they may ask you to come in — depending on your obstetric history, your risk factors, and how your contractions sound over the phone.

First labours typically take longer than subsequent ones, particularly the early latent phase. NICE defines established labour as 6 cm or more of dilation. Before this threshold, the evidence supports remaining at home where you are comfortable and labour can often progress more naturally than it does in a clinical setting.

For Second and Subsequent Pregnancies

The timing guidance changes significantly for second and subsequent births, because second labours are typically much faster — particularly the active phase. What took 12 hours in a first labour may take 3 hours or less the second time.

For second or subsequent births, the NHS advises calling when contractions are 3 to 4 minutes apart, rather than waiting for the 5-minute interval that applies to first births. Do not apply your previous labour's timing as a benchmark — second labours can progress to full dilation very quickly once they establish.

If you had a particularly fast first labour — defined by NICE as a labour that progressed from onset to birth in three hours or fewer — inform your midwife at an antenatal appointment. You should have a personalised plan that accounts for this, which may mean calling earlier and planning transport carefully.

If Your Waters Break

When the membranes rupture — whether with a sudden gush or a slow trickle — you should contact your maternity unit or midwife promptly, even if contractions have not started.

What NHS guidance says:

• If the amniotic fluid is clear, call your maternity unit to discuss next steps. Labour may start on its own within 24 hours.
• If the fluid is green, brown, or blood-stained, go to the maternity unit immediately. Green or brown fluid may indicate meconium, which can be a sign of fetal distress and requires prompt assessment.
• If your waters break and labour does not start within 24 hours, the NHS recommends being assessed and discussing induction of labour to reduce the risk of infection (chorioamnionitis).
• If you are Group B Streptococcus (GBS) positive — confirmed by a vaginal swab — you should go to the maternity unit immediately when your waters break. GBS can pass to the baby and requires IV antibiotics in labour.

It is worth noting that spontaneous rupture of membranes does not always result in the waters "breaking" dramatically. For many people, it is a slow leak that might be mistaken for increased vaginal discharge or urine leakage. If you are unsure, put on a clean pad and check after 30 minutes. Amniotic fluid is typically odourless, clear or slightly pale yellow, and continues to leak. If you are still uncertain, call your maternity unit — a simple test in triage can confirm whether it is amniotic fluid.

The Home Birth Option

If you are planning a home birth, the process works differently. Instead of going to the hospital, you call your community midwife team when labour is establishing.

For home births, NHS guidance generally advises calling when contractions are 4 to 5 minutes apart. Your midwife team will come to you. They will bring the equipment needed to monitor you and the baby safely, including resuscitation equipment for the newborn.

You should still have a clear plan for transfer to hospital if needed. Your midwives will advise transfer if:

• Labour is not progressing as expected
• There are concerns about your wellbeing or the baby's
• You request additional pain relief (specifically an epidural, which is not available at home)
• Any complication arises that requires obstetric review

Transfer rates from planned home births vary, but NICE data suggests around 45% of first-time parents who plan a home birth transfer during labour, compared with around 12% of people having a second or subsequent birth. This is not a failure — it is the system working as intended.

What Happens at Triage

If you call your maternity unit and are asked to come in, you will be assessed at the maternity triage or assessment unit. Knowing what to expect can reduce anxiety about the process.

A typical triage assessment includes:

• A discussion of your symptoms — when contractions started, how frequent they are, whether your waters have broken, whether there is any bleeding, how the baby has been moving.
• Blood pressure and urine check — routine observations that screen for pre-eclampsia and urinary infection.
• Abdominal examination (palpation) — your midwife will feel your abdomen to assess the baby's position, the engagement of the head, and uterine contractions.
• CTG monitoring — electronic monitoring of the baby's heart rate and your contractions for approximately 20–30 minutes. This assesses fetal wellbeing and confirms the contraction pattern.
• Vaginal examination (VE) — with your consent, the midwife will examine internally to assess cervical dilation. This is the definitive way to know what stage of labour you are in.

Based on the examination, you will either be:

• Admitted to the labour ward or midwife-led unit (active labour, typically 6 cm or more)
• Transferred to a birth centre or ward for monitoring if there are concerns
• Advised to return home if you are in early labour

If You Are Sent Home

Being assessed in triage and sent home can feel discouraging, particularly if contractions have been going on for hours and are genuinely uncomfortable. It is not a sign that your labour is not real, or that the midwife does not take your pain seriously. It is a reflection of evidence that early labour — before 6 cm — progresses better at home.

Research shows that people who remain at home during the latent phase of labour have lower rates of intervention, including epidurals and caesarean section, than those who are admitted early. The familiar environment, freedom to move, access to your own food, and reduced anxiety associated with home all contribute to better labour progress.

When you are sent home, you will be given clear written and verbal guidance about when to return. You should return when:

• Contractions reach the threshold discussed (usually 5 minutes apart for 1 hour, or 3 minutes apart for a second birth)
• Your waters break
• You experience any of the immediate warning signs listed below
• You are concerned for any reason

You are always permitted to call the maternity unit. There is no rule that says you can only call once things are serious. The team would rather speak to you at 3 am for reassurance than have you manage something alone that needed assessment.

When to Go Immediately

These situations require going to hospital immediately. Do not track contractions. Do not wait for a pattern to establish. Call 999 if needed, or go directly to the maternity unit.

Cord prolapse: If you feel or see a loop of umbilical cord at the vaginal opening after your waters break, call 999 immediately. This is a rare obstetric emergency in which the cord can be compressed by the baby's head, cutting off blood flow.

Heavy vaginal bleeding: A small amount of blood-streaked mucus (a "show") is normal in early labour. Bright red bleeding in a quantity larger than a period, or any bleeding that soaks a pad, requires immediate assessment. This may indicate placental abruption or another complication.

Green or brown amniotic fluid: Indicates possible meconium and requires prompt fetal monitoring.

Absent or significantly reduced fetal movement: If you cannot remember feeling the baby move in the last few hours, or the pattern of movement has changed significantly, go in. Do not wait for contractions to reach any particular threshold. RCOG guidance is explicit that reduced fetal movement should always be assessed promptly — this applies whether or not you are in labour.

Constant, severe abdominal pain that does not ease between contractions: Labour contractions build and release. Pain that is constant and does not ease may indicate placental abruption and needs immediate assessment.

Fitting, vision disturbances, severe headache, or sudden facial swelling: These can be signs of severe pre-eclampsia or eclampsia. Call 999.

You feel extremely unwell in a way that feels different from labour: Trust this. If something feels acutely wrong beyond the expected discomfort of labour, say so. Maternal instinct is not quantifiable, but clinicians take it seriously.

The Emotional Reality of Early Labour Management

Knowing the clinical guidelines is one thing. Experiencing early labour at home, particularly as a first-time parent, is another. Contractions that make it impossible to talk are difficult to manage anywhere, but managing them at home with hours still to go requires a specific kind of preparation.

A few things that help:

• Agree a plan with your birth partner in advance about how you will manage early labour together.
• Know who to call. Have the maternity unit number saved in your phone.
• Prepare the home environment — know where the TENS machine is, have a bag ready, have paracetamol, water, and easy food accessible.
• Rest when contractions allow. The ability to conserve energy in early labour has a real effect on how you feel in active labour.
• Remember that calling the maternity unit costs nothing and is always appropriate. You will never be judged for calling when something feels wrong.

Frequently Asked Questions

How do I know if I am in active labour?

Active labour is defined by NICE as cervical dilation of 6 cm or more. Clinically, this is confirmed by vaginal examination. Signs that suggest active labour is establishing include contractions lasting 60 seconds or more, coming every 3–5 minutes, and making it very difficult to speak or focus during them.

What if my contractions are irregular but very painful?

Pain intensity is not the same as labour progress. Contractions can be painful without following an established pattern. If pain is severe and unmanageable, call your maternity unit regardless of contraction frequency — particularly if it is your first pregnancy.

Can I eat before going to hospital?

In early labour at home, eating a light meal is appropriate. Most units prefer that you avoid large, heavy meals once you are in established labour, and you will not be permitted to eat once you have had an epidural.

My maternity unit is more than 30 minutes away — does this change when I should call?

Yes. If you live at a significant distance from your nearest maternity unit, factor in travel time when deciding when to call. Discuss this at a late pregnancy appointment so you have a personalised plan. Some people in this situation are advised to call earlier than the standard threshold.

I was sent home from triage but contractions are still painful — what do I do?

Manage contractions at home using the advice you were given. Use a TENS machine, warm bath, paracetamol, and movement. Call the maternity unit if contractions increase in frequency, your waters break, or you have any concerns. There is no rule about how quickly you can call back.

Is it safe to go to hospital in a taxi or should I call an ambulance?

For most people in uncomplicated labour, a taxi or private car is appropriate and faster than an ambulance. Call 999 if you suspect cord prolapse, are having a seizure, have very heavy bleeding, or birth appears imminent.

Key Takeaways

• For first births, call the maternity unit when contractions are regular, 5 minutes apart, lasting 60 seconds, for at least one hour.
• For second and subsequent births, call earlier — at 3 to 4 minutes apart — because labour typically progresses faster.
• If your waters break, call the maternity unit promptly. Go immediately if the fluid is green, brown, or blood-stained.
• Group B Strep carriers should go to hospital as soon as waters break for IV antibiotics.
• Being assessed in triage and sent home in early labour is evidence-based, not dismissive — active labour is defined as 6 cm dilation by NICE.
• Go immediately for heavy bleeding, cord prolapse, reduced fetal movement, constant severe pain, visual disturbances, or any feeling that something is acutely wrong.
