Signs of Labour: What to Watch and When to Call
Published 2026-07-08 | By SafeMama Editorial Team | Editorial policy
Short answer
Early signs include regular tightening contractions, a show, backache and waters breaking. NHS advises contacting your midwife or maternity unit when contractions are regular and strong, if your waters break, if there is any bleeding, or if the baby movements change.

Signs of Labour in pregnancy: how to think about it
NHS guidance describes several signs that labour may be starting: contractions or tightening that become regular and stronger, a show where the mucus plug comes away and may be tinged with blood, backache, an upset stomach, and waters breaking. Early or latent labour can last a long time, which is why the guidance separates the stage where staying home is reasonable from the point where contact matters. The signals that prompt immediate contact are specific rather than general. Waters breaking matters because the protective barrier is gone and the colour indicates whether the baby has passed meconium. Bleeding needs assessment because it can indicate a problem with the placenta. Contractions before 37 weeks matter because preterm labour changes what care is offered. And a change in baby movements at any point, including during labour, is treated the same way it is throughout pregnancy: call immediately.
Signs of Labour: safer choices
- Contacting your midwife or maternity unit when contractions become regular, last around a minute and come roughly every five minutes, or sooner if you are unsure.
- Expecting early labour to take time. NHS describes a latent phase that can last hours or longer, particularly in a first pregnancy.
- Staying at home in early labour if you are comfortable and have been advised to, using a warm bath, movement and paracetamol for the early stage.
- Contacting the unit at any hour if you are worried, even if the signs are ambiguous. Being checked unnecessarily is expected and welcome.
Signs of Labour: what to avoid or double-check
- Do not wait to call if your waters break, whatever the colour, and note the time and colour to report.
- Do not wait if there is any vaginal bleeding, if the fluid is green or brown, or if you feel feverish or unwell.
- Do not ignore a change in baby movements during early labour. Movements should continue during labour, and any change needs the same immediate call as at any other stage.
- Do not assume it is too early to be taken seriously. Contractions before 37 weeks need contact straight away, since that is preterm labour.

Frequently asked questions
When should I call the maternity unit in labour?
When contractions are regular, strong and roughly five minutes apart, or immediately if your waters break, there is bleeding, the fluid is green or brown, or baby movements change.
How long does early labour last?
It varies widely. NHS describes a latent phase that can last many hours, particularly in a first pregnancy. Staying home during that stage is common if you have been advised it is fine.
My waters broke but I have no contractions. What now?
Contact your maternity unit straight away regardless. Note the time and the colour of the fluid, and report both.
What is a show?
The mucus plug coming away from the cervix, sometimes tinged with blood. It can happen days before labour and is not itself a reason to go in, but mention it to your midwife.
I am having contractions before 37 weeks.
Contact your maternity unit immediately. Contractions before 37 weeks may be preterm labour, which changes the care that is offered.
Should the baby still move during labour?
Yes. Movements should continue during labour, and any change needs the same immediate call as at any other point in pregnancy.
