The first labor signs can feel surprisingly ordinary. You might notice cramps that come and go, a dull ache in your lower back, or a tightening that makes you pause halfway through a conversation. One useful clue is how those sensations change over time. Contractions that grow stronger, last longer, and come closer together are more likely to mean labor is progressing.
Call your maternity team immediately if you think your water has broken, you have vaginal bleeding, your baby’s movements slow down, stop, or change, or you have possible labor symptoms before 37 weeks. Call even if it’s the middle of the night. If you have a strong urge to push and think your baby is coming now, call your local emergency number for an ambulance.
What Are the Early Signs of Labor?
Labor can start gradually, and the first sign won’t be the same for everyone. You may notice contractions first, see a change in discharge, or feel fluid leaking before you feel any tightening. Here’s what those changes can look and feel like.
Cramps or Belly Tightening That Comes in Waves
A contraction happens when your uterus tightens and then relaxes. Your belly may feel firm during the wave and soften as it passes. You might feel period-like cramps low in your belly, pressure in your pelvis, or an ache in your lower back.
Early contractions can be unevenly spaced. One might make you pause what you’re doing, while the next feels milder. As labor progresses, contractions generally become stronger, last longer, and occur more frequently. The pattern across several contractions usually tells you more than any one wave.
Sticky Mucus or a Pink-Tinged “Show”
You may see thick, jelly-like mucus in your underwear or when you wipe. A little pink or blood-streaked mucus can be a show, which happens when the cervix begins to open and the mucus plug comes away. It may come out at once or in smaller pieces.
Labor can follow soon or take a few days, and some people never notice a show. If you see vaginal bleeding apart from a slight streak in the mucus, or you aren’t sure whether what you’re seeing is a show, call your maternity team immediately.
Lower Backache or More Pressure in Your Pelvis
When your baby settles lower, you may feel more pressure in your pelvis or notice that you need to use the bathroom more often. An aching lower back can also be part of early labor, particularly if it comes in waves with belly tightening.
Your baby can move lower well before birth, so pressure alone doesn’t tell you when labor will begin. If you’re under 37 weeks and develop new downward pressure, an unusual backache, or period-like cramps, call your maternity team right away, even if the symptoms are mild.
A Trickle or Gush of Fluid
Your water can break before contractions start or during labor. It might feel like a sudden gush or a slow trickle you can’t control. It can be hard to tell amniotic fluid from urine, especially when there’s only a little at a time.
If you think your water has broken, call your maternity team immediately, even if you feel fine and have no contractions. Use a clean sanitary pad rather than a tampon. Tell the team when the leaking started and whether the fluid is clear, green, brown, bloody, or has an unpleasant smell. Make the call even if you aren’t sure what the fluid is.
How Do I Know If I’m in Labor?
Look at what happens across several contractions. Braxton Hicks contractions often come and go without a steady pattern and may ease when you rest or change position. Labor contractions generally keep coming and build over time.
| What you notice | Braxton Hicks contractions | Labor contractions |
|---|---|---|
| Timing | Often irregular, with no clear trend | Tend to become more regular and come closer together |
| Strength | May stay about the same, vary, or ease | Usually get stronger as labor progresses |
| Duration | May vary without getting longer | Tend to last longer over time |
| Rest or a change of position | May help the tightening settle | Contractions generally continue as labor progresses |
These are clues you can use to describe what’s happening. Early labor can be irregular, and practice contractions can feel uncomfortable. Sometimes an examination is needed to tell whether your cervix is changing. If you’re unsure, your maternity team can help you decide what to do next.
How to Time Contractions
- Duration: Count from the start of a contraction until it ends.
- How far apart they are: Count from the start of one contraction to the start of the next.
For example, if a contraction begins at 8:00 and ends at 8:00:45, it lasts 45 seconds. If the next one begins at 8:06, the contractions are six minutes apart.
A rough record can help your maternity team, but it’s fine if you don’t have exact times. If you notice an urgent symptom, call as soon as you notice it. You can explain what you’ve felt without waiting to time more contractions.
When to Call Your Maternity Team About Labor
Call your doctor, midwife, or labor and delivery unit if you think labor has started or you’re unsure what your symptoms mean. Follow the instructions your own team gave you about when to call or come in. As a general example, NHS guidance advises calling when contractions are regular and coming every five minutes or more often. If your care team has given you different instructions, use those.
Call your maternity team immediately if:
- You think your water has broken, even without contractions.
- You have vaginal bleeding beyond a little pink or blood-streaked mucus, or you’re unsure whether it’s a show.
- Your baby moves less than usual, stops moving, or changes their usual movement pattern.
- You’re under 37 weeks and have possible labor symptoms, including regular tightening, unusual backache, period-like cramps, new pelvic pressure, or leaking fluid.
- You have severe belly pain that continues between contractions.
- Any contraction lasts longer than two minutes, or you have six or more contractions in ten minutes.
Call your local emergency number for an ambulance if you have a strong urge to push and think the baby is coming now. Heavy bleeding, collapse, or serious trouble breathing also requires emergency help.
When you call, start with how many weeks pregnant you are and what prompted the call. If you can, mention when the symptoms began, how often the contractions are coming, and whether you’ve noticed fluid, bleeding, or a change in your baby’s movements. You can say, “I’m 39 weeks pregnant, and I think my water may have broken. I haven’t felt any contractions yet. What should I do?”
What Can Help You Feel More Comfortable in Early Labor?
If your maternity team advises you to stay home for now, try resting between contractions, taking a warm shower, or moving gently if that feels good. Slow breathing may help you through a wave. If you’d rather sit quietly or lean on a support person, that’s fine too.
Give your support person a specific job if it helps. They can time a few contractions, get your things ready, or speak with the maternity team while you focus on getting comfortable. If the pattern changes, a warning sign appears, or you become worried, call your maternity team again. A previous call doesn’t mean you have to wait if something new happens.
Frequently Asked Questions
1. What do early labor contractions feel like?
They may feel like period cramps, tightening across your belly, or an ache in your lower back. The sensation may build, peak, and ease as your uterus relaxes. Early waves can be irregular, so notice whether they gradually become stronger, longer, and closer together.
2. What are the clearest signs labor is starting?
Contractions that keep coming and build in strength and frequency are a useful clue. Your water breaking or a pink-tinged mucus show can also happen around the start of labor. A show alone can’t tell you when you’ll give birth.
3. Can labor start before my water breaks?
Yes. Contractions can start while the amniotic sac is still intact. If your water breaks first, call your maternity team immediately, even if contractions haven’t started.
4. Should my baby still move during labor?
Yes. You should continue to feel your baby move up to and during labor. Call your maternity team immediately if movement slows, stops, or changes from your baby’s usual pattern.
5. Can I be in early labor if my contractions are irregular?
Yes. Early contractions may be unevenly spaced and vary in strength. If they keep returning or you think labor is starting, call for advice. Don’t wait for a regular pattern if you have an urgent symptom.
6. Does losing the mucus plug mean I’ll give birth today?
It doesn’t give you a reliable timeline. Labor may follow soon, or it may take a few days. If you’re unsure whether you’re seeing blood-streaked mucus or vaginal bleeding, call your maternity team right away.
7. What if I can’t tell whether my water broke or I leaked urine?
Put on a clean sanitary pad and call your maternity team. Tell them when you noticed the fluid, whether it keeps leaking, and what it looks and smells like. You don’t have to identify it yourself before calling.
8. Should I wait until contractions are five minutes apart?
Follow your maternity team’s instructions. If you think labor has started or you’re worried, you can call before contractions reach that interval. Never wait for a timing target if your water may have broken, you’re bleeding, your baby’s movements change, or you may be in labor before 37 weeks.
9. What if I have period-like cramps before 37 weeks?
Call your maternity team immediately if the cramps could be a sign of labor, especially if you also notice pelvic pressure, an unusual backache, tightenings, or fluid leaking. You don’t need to wait for the cramps to become painful or regular.
10. Can a warm shower tell me whether I’m in labor?
No. A warm shower can help you feel more comfortable, but how you feel afterward doesn’t confirm whether your cervix is changing. Call your maternity team if you’re unsure, and don’t try a shower first if you have an urgent symptom.
Final Thoughts
The first few contractions can leave you wondering whether anything has really started. If the waves keep coming, notice how they change and tell your maternity team what you’re feeling. “Something feels different” is enough to start the conversation.
Keep your maternity team’s number somewhere you and your support person can find it quickly. If you notice a warning sign, call right away. You don’t need a complete contraction log or a definite answer before asking for help.
