Labour rarely starts without warning. Your body sends clear signals in the days and hours before birth begins. These signs are called pre-labour or early labour signs. They are your body’s way of preparing for delivery.
The most reliable sign is regular contractions that get stronger and closer together. But many women notice other changes first. Understanding these signs helps you know when to stay home and when to call your midwife or doctor.
No two labours are the same. Some women have several warning signs for weeks. Others only notice signs a few hours before labour starts. Here is what to look for and what each sign means.
What Are the First Physical Signs of Labour?
The first signs of labour are physical changes your body makes to prepare for birth. These happen before active labour begins.
Lightening is when your baby drops lower into your pelvis. This usually happens 2 to 4 weeks before labour for first-time mothers. For women who have given birth before, lightening may not happen until labour starts. You may find it easier to breathe after lightening because your baby is no longer pressing on your diaphragm. You may also need to urinate more often because your baby now presses on your bladder.
Increased vaginal discharge is another early sign. Your body produces more discharge in late pregnancy to keep the birth canal clean. This discharge is normally clear or slightly milky. If the amount increases noticeably, labour may be approaching.
Loose stools or mild diarrhoea can occur 24 to 48 hours before labour. The same hormones that soften your cervix also relax your bowel muscles. This is a normal response and not a cause for concern unless you also have fever or severe pain.
A surge of energy sometimes called “nesting,” can happen 24 to 48 hours before labour. Many women feel a sudden urge to clean, organise, or prepare the nursery. This burst of energy is driven by hormonal changes. It is not a guaranteed sign of labour, but it is common.
How Do You Know When Labour Is Near? Look for These Signs
Some signs are stronger indicators than others. The following signals suggest labour is genuinely close, usually within days or hours.
The mucus plug is a thick jelly-like substance that seals your cervix during pregnancy. When your cervix begins to soften and open, the plug comes out. You may notice it as a large blob of mucus or as increased discharge over several days. It can be clear, pink, or slightly blood-streaked. This is often called a “show.” Losing your mucus plug means your cervix is changing, but labour may still be days away.
Your waters breaking is a clear sign labour is near. This happens when the amniotic sac ruptures. You may feel a gush of fluid or a slow trickle. Amniotic fluid is usually clear and odourless. If your waters break, call your healthcare provider. Most women go into labour within 24 hours after their waters break. If contractions do not start, your provider may recommend induction to reduce infection risk.
Regular contractions are the most definitive sign. True labour contractions come at regular intervals and get closer together over time. They last longer and feel stronger as labour progresses. Walking often makes true contractions stronger. Resting does not stop them.
Braxton Hicks contractions are different. These are practice contractions that stay irregular and do not get stronger. They often stop when you change position or rest. Timing your contractions helps you tell the difference.
What Do Real Labour Contractions Feel Like?
Real contractions feel like strong menstrual cramps that spread across your abdomen and lower back. The pain builds to a peak and then slowly fades. Between contractions, you get a rest period.
In early labour, contractions may feel mild and last about 30 to 45 seconds. They may come every 5 to 20 minutes. As labour progresses, contractions last about 60 seconds and come every 3 to 4 minutes.
You can time contractions from the start of one to the start of the next. Keep a record of how long each contraction lasts and how far apart they are. Call your provider when contractions are regular, strong, and coming every 5 minutes for at least an hour. This is a general guideline. Your provider may give you different instructions based on your specific situation.
Contractions that stop when you rest are usually not real labour. Real contractions continue regardless of your activity level. They also intensify over time rather than staying the same.
What Is the Difference Between Early Labour and Active Labour?
Labour is divided into stages. Early labour is the first stage. Active labour is when your cervix dilates from about 6 centimetres to fully open at 10 centimetres.
Early labour can last for hours or even days. Contractions are often irregular and mild. You can usually talk through them. Many women rest, eat light meals, and stay hydrated during early labour at home.
Active labour is more intense. Contractions are stronger, longer, and closer together. You may find it hard to talk during a contraction. You may feel pressure in your lower back and pelvis. This is when most women go to the hospital or birth centre.
Your cervix must dilate to 10 centimetres for you to push. Your healthcare provider will check your cervix to confirm you are in active labour. Cervical checks are the most accurate way to know how far labour has progressed.
When Should You Call Your Midwife or Doctor?
Call your healthcare provider when you have any of these signs:
- Your waters break, even if you are not having contractions
- Contractions are 5 minutes apart for 1 hour
- Contractions are so strong you cannot walk or talk through them
- You have vaginal bleeding that is more than a pink or bloody show
- You notice decreased fetal movement
- You have severe, constant pain between contractions
If you are less than 37 weeks pregnant and notice any signs of labour, call your provider immediately. This could be preterm labour and needs urgent medical attention.
Trust your instincts. If something feels wrong, call. Labour care providers expect calls from concerned mothers. They would rather you call too early than too late.
What Should You Do When Labour Signs Start?
When you first notice signs of labour, stay calm. Early labour can last a long time, and you will need your energy later.
Rest as much as you can. Lie down or sit in a comfortable position. Take a warm shower or bath if your waters have not broken. This can ease discomfort and help you relax.
Eat light foods that are easy to digest. Toast, soup, yoghurt, and fruit are good options. Avoid heavy or greasy meals. Stay hydrated by sipping water or clear fluids throughout early labour.
Use distraction to pass the time. Watch a film, read a book, or listen to music. Gentle walking can help labour progress if you feel up to it.
Prepare your hospital bag and make sure your birth partner knows the plan. Double-check your route to the hospital or birth centre and confirm who will care for older children or pets.
Frequently Asked Questions
How close together do contractions need to be before I go to the hospital?
Most providers recommend going to the hospital when contractions are 5 minutes apart, lasting about 1 minute, for at least 1 hour. Follow the specific instructions your own provider gave you, as these can vary.
Can losing your mucus plug mean labour is days away?
Yes, losing your mucus plug means your cervix is starting to change, but labour may not start for several days. Some women lose their mucus plug up to two weeks before labour begins.
What should I do if my waters break but I have no contractions?
Call your healthcare provider right away. Most women go into labour within 24 hours after their waters break, and your provider will advise you on next steps to reduce the risk of infection.
How can I tell the difference between Braxton Hicks and real contractions?
Braxton Hicks contractions are irregular, do not get stronger, and often stop when you change position or rest. Real contractions come at regular intervals, get closer together, and continue regardless of what you do.
