Signs of Labour: What to Watch For
Feel calm and prepared by learning to recognise the unique signs that your body and baby are ready for birth.
As your due date approaches, you may find yourself wondering how you will know when labour truly begins. Understanding the signs of labour can help you feel more prepared and confident about when to take action, whether that is calling your midwife, heading to hospital, or simply continuing to wait patiently at home. Every woman's experience of labour is unique, but there are common signs that indicate your body is preparing for or beginning the process of giving birth.
Early signs of labour
In the days and weeks leading up to labour, your body begins preparing for birth. These early signs do not necessarily mean labour will start immediately, but they indicate that your body is getting ready:
Lightening or engagement
Also known as "dropping," this occurs when your baby's head moves down into your pelvis, typically 2-4 weeks before labour in first pregnancies, though it may happen closer to labour in subsequent pregnancies:
- You may notice your bump looks lower or different in shape
- Breathing becomes easier as pressure is taken off your diaphragm
- You may feel increased pressure in your pelvis and bladder
- Walking may become more uncomfortable
- You might need to urinate more frequently
Braxton hicks contractions
These practice contractions become more frequent and noticeable as your due date approaches:
- Irregular tightening of your uterus that comes and goes
- Generally painless, though they may become uncomfortable
- Often triggered by activity, dehydration, or a full bladder
- Typically ease with rest, change of position, or hydration
- Do not follow a regular pattern or increase in intensity
Nesting instinct
Many women experience a sudden burst of energy and an overwhelming urge to prepare their home:
- Intense desire to clean, organise, or complete baby preparations
- Feeling energised despite being in late pregnancy
- Compulsion to ensure everything is "ready" for baby's arrival
- May occur days or weeks before labour begins
Changes in cervix
Your cervix begins to soften, thin (efface), and possibly dilate in preparation for labour:
- These changes may be detected during routine antenatal appointments
- You will not necessarily feel these changes happening
- Some women may be several centimetres dilated weeks before labour begins
- Others may not dilate until labour is well established
Definitive signs of labour
These signs indicate that labour has likely begun and you should start timing events and preparing to contact your midwife or birthing team:
Regular, progressive contractions
True labour contractions have distinct characteristics that differentiate them from Braxton Hicks:
- Regularity: Contractions follow a consistent pattern, coming at regular intervals
- Progressive intensity: They gradually become stronger, longer, and more painful
- Duration: Each contraction typically lasts 30-70 seconds
- Frequency: They occur every 3-5 minutes in established labour
- Persistence: They continue regardless of rest, position changes, or hydration
- Location: Pain often starts in your back and moves forward to your abdomen
Timing Contractions: When contractions become regular, start timing them from the beginning of one contraction to the beginning of the next. Note both the frequency (how often they occur) and duration (how long each one lasts).
Waters breaking (rupture of membranes)
Your waters may break before or during labour, and the experience can vary significantly:
- Dramatic gush: A sudden release of a large amount of clear or slightly yellow fluid
- Slow leak: A steady trickle of fluid that you might initially mistake for urine
- Multiple gushes: Fluid released in several smaller amounts over time
- During labour: Waters may not break until well into the labour process
Key points about waters breaking:
- Only about 10-15% of women experience waters breaking before contractions begin
- The fluid should be clear or slightly yellow with a sweet smell
- If fluid is green, brown, or has a strong odour, contact your midwife immediately
- Once waters break, there is an increased risk of infection, so labour usually needs to begin within 24 hours
Bloody show or mucus plug
The loss of your mucus plug is another sign that labour may be beginning:
- A thick, jelly-like discharge that may be clear, pink, or slightly bloody
- May come away gradually over several days or all at once
- Indicates that your cervix is beginning to open
- Labour may begin within hours or up to a week after losing the plug
- Not all women notice losing their mucus plug
Understanding the stages of labour
Labour is divided into three distinct stages, each with its own characteristics and duration:
First stage: early and active labour
The first stage is the longest part of labour and is divided into two phases:
Early Labour (Latent Phase)
- Cervix dilates from 0-4 centimetres
- Contractions are mild to moderate and may be irregular
- Can last 6-12 hours for first-time mothers, shorter for subsequent births
- You can usually manage at home during this phase
- Good time to rest, eat light meals, and stay hydrated
Active labour
- Cervix dilates from 4-10 centimetres
- Contractions become stronger, longer, and more frequent
- Usually lasts 4-8 hours for first-time mothers
- This is typically when you will want to be at your chosen birthing location
- Pain relief options become more important during this phase
Second stage: pushing and birth
This stage begins when your cervix is fully dilated (10cm) and ends with your baby's birth:
- You will feel an overwhelming urge to push
- Contractions may space out slightly, giving you rest between pushes
- Can last 30 minutes to 3 hours for first-time mothers
- Usually shorter (under an hour) for subsequent births
- Your midwife will guide you on when and how to push effectively
Third stage: delivery of placenta
After your baby is born, your uterus continues to contract to deliver the placenta:
- Usually completed within 30 minutes of birth
- You may have managed or physiological third stage
- Mild contractions help separate and expel the placenta
- Your midwife will examine the placenta to ensure it is complete
When to contact your midwife
Knowing when to call your midwife or maternity unit is crucial for ensuring you receive appropriate care at the right time:
Contact immediately if:
- Waters break: Especially if the fluid is not clear or if you are less than 37 weeks pregnant
- Heavy bleeding: More than a heavy period or bright red blood
- Severe, constant abdominal pain: That does not ease between contractions
- Reduced baby movements: If you notice a significant decrease in your baby's normal movement pattern
- Visual disturbances: Seeing spots, flashing lights, or severe headaches
- Signs of infection: Fever, chills, or foul-smelling discharge
Contact when:
- Regular contractions: Coming every 3-5 minutes and lasting 45-60 seconds for at least an hour
- First baby: When contractions are strong and regular, even if they are not yet very close together
- Subsequent babies: When contractions become regular, as labour may progress more quickly
- You are concerned: Trust your instincts - if something does not feel right, it is always better to check
Information to have ready
When you call your midwife or maternity unit, be prepared to provide:
- Your name, date of birth, and NHS number
- Your estimated due date
- Details about contractions (frequency, duration, intensity)
- Whether your waters have broken and the colour of the fluid
- Any bleeding or discharge
- Your baby's movements
- Any other symptoms or concerns
Common misconceptions about labour signs
There are several myths about labour that can cause unnecessary anxiety or confusion:
Myth: "labour always starts with waters breaking"
Reality: Only about 10-15% of women experience their waters breaking before contractions begin. For most women, contractions start first, and waters break during labour or may even need to be broken artificially.
Myth: "if your waters break, you must rush to hospital immediately"
Reality: Whilst you should contact your midwife when your waters break, if the fluid is clear and you are full-term, you do not necessarily need to rush to hospital. Your midwife will advise you based on your specific circumstances.
Myth: "labour pain is unbearable from the start"
Reality: Labour typically starts gradually, with mild contractions that build in intensity over time. Early labour is often manageable, and there are many pain relief options available as labour progresses.
Myth: "first babies always come late"
Reality: Whilst first labours tend to be longer, first babies can arrive early, on time, or late. Only about 5% of babies arrive on their exact due date.
Myth: "you will definitely know when you are in labour"
Reality: Many women, especially first-time mothers, are unsure whether they are in early labour or experiencing strong Braxton Hicks contractions. This uncertainty is completely normal.
Preparing for labour
Being prepared can help you feel more confident when labour signs begin:
Create a birth plan
- Discuss your preferences for pain relief, positions, and interventions
- Consider who you want as your birth partner
- Think about your preferred environment and atmosphere
- Remember that birth plans are flexible - labour may not go exactly as planned
Pack your hospital bag
Have your bag ready by 36 weeks, including essentials for labour, after birth, and your baby:
- Comfortable clothes and nightwear for labour and after birth
- Toiletries and personal items
- Baby clothes in newborn and 0-3 month sizes
- Nappies, blankets, and car seat for the journey home
- Snacks and drinks for after birth
- Important documents and contact numbers
Know your route
- Plan the quickest route to your chosen birthing location
- Consider alternative routes in case of traffic
- Know where to park or arrange transport
- Have contact numbers readily available
Discuss plans with your birth partner
- Ensure they understand the signs of labour
- Share your birth preferences and discuss their role
- Make sure they know when and how to contact your midwife
- Discuss comfort measures they can help with during labour
Dealing with false alarms
It is common to have several false alarms before real labour begins, especially with your first baby:
Do not feel embarrassed
- Many women contact their midwife multiple times before labour truly begins
- Healthcare providers expect this and would rather assess you than miss the real thing
- Each "practice run" helps you become more familiar with your body's signs
- Being sent home is not a failure - it is all part of the normal process
What to do during false alarms
- Try to rest and conserve energy for when real labour begins
- Stay hydrated and eat light, nutritious meals
- Use relaxation techniques to manage any discomfort
- Time contractions to see if they follow a pattern
- Take a warm bath or shower, which may ease Braxton Hicks contractions
Special circumstances
Some situations require particular attention when it comes to recognising labour signs:
Previous quick labours
If you have had a previous labour lasting less than 3 hours, you should:
- Contact your midwife as soon as regular contractions begin
- Consider staying closer to your birthing location as your due date approaches
- Have a clear plan for quick transport to hospital
- Discuss the possibility of a home birth if appropriate
High-risk pregnancies
If you have pregnancy complications, you may need to contact your healthcare provider earlier:
- Follow specific guidance given by your consultant or midwife
- Be aware of any additional warning signs specific to your condition
- Do not hesitate to contact your team if you are unsure about any symptoms
- Ensure you are familiar with the direct contact numbers for your specialist team
Planned caesarean section
Even with a planned caesarean, labour may begin before your scheduled date:
- Contact your maternity unit immediately if you think labour has started
- Your caesarean may need to be brought forward
- Do not eat or drink once labour signs begin
- Go directly to hospital rather than calling first
Frequently asked questions
In the weeks or days before birth, your body enters a pre-labour phase. You may notice the baby "dropping", moving down into your pelvis, which can make breathing easier but increases pressure on your bladder and a waddling sensation when walking. Braxton Hicks practice contractions may become more noticeable, and many women experience a sudden burst of nesting energy to clean and organise. These signs indicate birth is near, though active labour could still be days away.
Braxton Hicks contractions are irregular, do not increase in intensity, and often stop if you change position, rest, or drink water. True labour contractions follow a strict pattern. They come at predictable intervals, get closer together, longer, and stronger over time, and crucially do not stop if you lie down or take a bath. Time your contractions from the start of one to the start of the next to track their frequency and duration.
Waters breaking, the rupture of the membranes, can be a dramatic gush or a slow, steady trickle. The fluid should be clear or pale straw-coloured. Contact your midwife immediately if the fluid is green or brown, which indicates meconium and requires prompt assessment. You should also call straight away if you notice heavy bright red bleeding. Waters breaking is always a reason to contact your midwife, regardless of whether contractions have started.
A bloody show occurs when the mucus plug that has sealed the uterus during pregnancy comes away as the cervix softens and thins. It typically looks like a stringy, pink, or blood-tinged discharge. It is a normal sign that your body is preparing for labour, though active labour may still be hours or days away. It is different from heavy vaginal bleeding, which requires immediate medical attention.
Contact your midwife immediately if your waters break, you notice reduced baby movements, you have heavy vaginal bleeding, you experience a severe headache or visual disturbances, or you are less than 37 weeks and feel regular tightening. For established labour, most hospitals advise calling when contractions are 5 minutes apart, lasting 1 minute each, and have been consistent for 1 hour. It is always better to call and be reassured than to wait in doubt.
No. This is a common misconception. Waters breaking dramatically before contractions start only happens in around 15% of cases. For most women, contractions begin first. Similarly, first babies are not always late, though it is common. And if you go to hospital and are sent home because labour has not established, this is not embarrassing, midwives expect and welcome these visits as a normal part of the process.
The first stage is when the cervix opens from 0cm to 10cm. It includes an early latent phase and an active phase as contractions intensify. The second stage begins when you are fully dilated and ends with the birth of your baby. This is the pushing phase where you actively help move the baby out. The third stage involves the uterus contracting one final time to deliver the placenta, usually within 5 to 30 minutes of birth.
Final thoughts
Recognising the signs of labour is an important part of preparing for your baby's arrival. Whilst every woman's experience is unique, understanding these common signs can help you feel more confident about when to take action and what to expect during the labour process.
Remember that labour is a natural process that your body is designed to handle. Trust your instincts, stay calm, and do not hesitate to contact your healthcare team whenever you have concerns.
Preparing for labour involves not just understanding the physical signs, but also feeling emotionally ready and well-supported throughout the process. Having access to personalised care that takes into account your individual circumstances, concerns, and birth preferences can make a significant difference to your confidence and overall birth experience.
