Contractions are one of those things that everyone assures you “you will know when it is happening” while being conspicuously vague about what it actually feels like. Some people describe early contractions as period cramps. Others describe them as pressure waves. Others say they felt nothing like they expected. All of those accounts are accurate for someone.
This guide gives you the most honest and specific description of what contractions feel like at different stages of labour, how to distinguish early labour from other sensations, and what you are likely to experience as things progress.

What Contractions Are
A contraction is a tightening and shortening of the uterine muscle. The uterus is a large, hollow muscle and during labour it contracts rhythmically to efface (thin) and dilate (open) the cervix, and eventually to push the baby out.
The sensation you experience is caused by two things: the physical tightening of the muscle, and the reduced blood flow to the uterine tissue that occurs when the muscle contracts. That reduced blood flow creates an ache similar to the ache of a muscle in extended use, which is part of why labour is physically demanding.
What Early Contractions Feel Like
Early contractions, sometimes called latent phase contractions, are the contractions that begin the process of cervical effacement before active labour begins. Many people experience these for hours or even days before labour becomes established.
Period-Like Cramps
The most common description of early contractions is that they feel like period cramps, or like severe period cramps. The sensation is located low in the abdomen, sometimes radiating into the lower back and thighs. It builds gradually, reaches a peak and then fades.
The key difference from actual period cramps is that contractions are rhythmic. They come, they peak, they ease, they go. And then they come again.
Lower Back Ache
Many people experience contractions primarily or partly as lower back pain. This is especially common when the baby is in the occiput posterior position (back to back), where the baby’s skull presses against the maternal sacrum. Back labour can be more intense than anterior labour because of the pressure on the lower spine.
A Tightening or Hardening Sensation
If you place your hand on your abdomen during a contraction, you will feel the uterus become very hard, like a tensed muscle. The sensation you feel internally is that same tightening, experienced from the inside. Some people describe it primarily as pressure rather than pain, particularly in the early stages.
Braxton Hicks Versus Real Contractions
Braxton Hicks contractions are practice contractions that occur throughout the third trimester (and sometimes earlier). The distinction between Braxton Hicks and early labour contractions is one of the most frequently asked questions in pregnancy.
Braxton Hicks:
- Irregular, without a consistent pattern
- Do not increase in frequency or intensity over time
- Often ease when you change position, walk, or drink water
- Usually felt as tightening rather than pain
- Do not cause cervical change
Real contractions:
- Regular, with a consistent pattern that becomes more frequent over time
- Increase in intensity regardless of what you do
- Continue or worsen when you change position or move
- Often felt as both tightening and discomfort or pain
- Cause the cervix to efface and dilate
The rule of thumb “if it stops when you walk, it’s Braxton Hicks; if walking makes it more intense, it’s probably real” is broadly accurate.
What Active Labour Contractions Feel Like
Active labour begins when the cervix reaches approximately 6 centimetres dilation, though this definition has been revised in recent years. By this stage, contractions are well established and clearly felt.
Intensity That Builds
Active labour contractions are significantly more intense than early labour contractions. The build from the beginning of the contraction to the peak is longer and the peak itself is stronger. Many people describe them as waves: the sensation rises from below, reaches a peak that requires full focus to manage, and then recedes.
Duration
Active labour contractions typically last 45 to 90 seconds. This is longer than early contractions (which may last 20 to 45 seconds). The sensation at the peak of a 60 to 90 second contraction is the most demanding part of labour for most people.
The Rest Period
Between active labour contractions, most people feel entirely or almost entirely normal. This rest period, typically 3 to 5 minutes in active labour, is the body’s way of allowing recovery before the next contraction. Using these rest periods, even briefly, is one of the most important things you can do to sustain your energy through labour.
Where It Is Felt
In established labour, the sensation typically spreads from the lower abdomen through the hips, lower back and sometimes down the thighs. The pressure on the pelvis becomes more pronounced as the baby descends.
What Transition Feels Like
Transition is the period between active labour and the pushing stage, occurring between approximately 8 and 10 centimetres dilation. It is typically the most intense period of labour and also, in most cases, the shortest.
Overwhelming Intensity
Transition contractions come more quickly and last longer than active labour contractions, with a much shorter rest period between them. Some people in transition describe feeling as though contractions are continuous with very little gap.
The Urge to Give Up
Transition is the phase during which many people feel they cannot continue. The irony of this is that transition is the end. By the time most people feel they cannot go on, they are within an hour of meeting their baby. Midwives recognise the feeling of despair in transition as a positive sign.
Physical Symptoms
Transition often brings additional physical experiences alongside the contractions: shaking, nausea, feeling extremely hot or cold, feeling frightened or very emotional. All of these are normal and are caused by the hormonal and physical intensity of this stage.
What Pushing Contractions Feel Like
Once the cervix is fully dilated, the sensation changes.
The Urge to Push
Many people describe an involuntary urge to push during contractions, similar to (but much stronger than) the urge to open the bowels. This reflex is called the Ferguson reflex. It is involuntary and powerful. With some analgesics, particularly epidurals, this urge may be reduced or absent, requiring more directed pushing guidance from the midwife.
Relief
Many people find the pushing stage a relief after transition, because there is something active to do with the energy of the contraction. The sensation of pushing is intense but has a different quality from the passive experience of dilation contractions.
The Ring of Fire
As the baby’s head crowns (stretches the perineum to its fullest extent), many people experience what is commonly called the “ring of fire”: an intense burning sensation around the vaginal opening. This sensation is the stretching of tissue at its maximum. It lasts only a short time and is the immediate precursor to the birth of the head.
Pain Management and How It Changes the Experience
Without Pain Relief
Unmedicated labour allows the full experience of the sensations described above. Many people who birth without pain relief describe contractions as extremely painful but manageable with breathing, movement and support. The natural endorphin release that accompanies labour helps modulate the experience.
With Gas and Air (Entonox)
Gas and air does not eliminate the sensation of contractions. It creates a dissociative effect, making the peak feel slightly distant and more manageable. Some people find it helpful; others find it makes them feel nauseous or disconnected.
With an Epidural
An effective epidural significantly reduces or eliminates the sensation of uterine contractions. Some people with epidurals feel pressure during contractions but not pain. Others feel nothing until the pushing stage. With a low-dose mobile epidural, some sensation and movement is usually preserved.
With Remifentanil Patient-Controlled Analgesia
Remifentanil (a short-acting opioid given as a patient-controlled intravenous drip) reduces the peak of contraction pain without eliminating sensation. It requires continuous monitoring but allows more mobility than an epidural.
Practical Things That Help During Contractions
Movement
Moving during contractions, particularly rocking, swaying or walking, keeps the pelvis mobile and often reduces the intensity of the sensation. Remaining still is rarely the most comfortable option.
Water
Labouring in a bath or birth pool is one of the most effective non-pharmacological pain management options. Water provides buoyancy, warmth and a reduction in the sensation of gravity, all of which can make contractions more manageable.
Breathing
Specific breathing patterns (slow, deep breaths that expand the lower ribs on the inhale, and long controlled exhales) help the nervous system maintain a parasympathetic (rest and recover) state rather than a sympathetic (fight or flight) state. The difference in experience can be significant.
Counterpressure
Firm, sustained pressure on the lower back during contractions, applied by a partner or midwife, relieves the back pain component of contractions for many people.
Warmth
A heat pack or wheat bag applied to the lower back during contractions reduces muscle spasm and provides a competing sensory input.
When to Go to Hospital or Call Your Midwife
The general guidance in the UK for people with a straightforward pregnancy is to contact your midwife or go to hospital when contractions are:
- Coming regularly every 5 minutes
- Lasting at least 60 seconds each
- Continuing consistently for at least an hour
This is often called the 5-1-1 rule. However, you should always call your maternity unit if you are unsure, if you have any concerns about the baby’s movements, if your waters have broken, or if you feel something is wrong regardless of whether the 5-1-1 rule is met.
