What do birth cramps feel like?

Birth cramps, also known as labor contractions, refer to the painful tightening and contracting of the uterus that occur during the different stages of labor prior to childbirth. These cramps are a normal part of the birthing process as the uterus works to push the baby down into the birth canal. While everyone’s experience is different, most women describe labor cramps as an intense sensation of pressure or squeezing in the lower abdomen or back.

What causes birth cramps?

During pregnancy, the uterus remains relaxed to accommodate the growing baby. As delivery approaches, the body releases hormones that cause the uterine muscles to contract intermittently. These contractions are what cause the sensations of cramping or tightening. The contractions become progressively stronger and more frequent as labor progresses to help dilate the cervix and move the baby into position for delivery.

Hormones involved

The main hormones involved in initiating labor contractions are:

  • Oxytocin – Produced by the pituitary gland, oxytocin stimulates contractions of the uterine muscles.
  • Prostaglandins – These fatty acids cause the cervix to ripen and soften to prepare for delivery.
  • Estrogen – Levels of this hormone rise towards the end of pregnancy, playing a role in strengthening contractions.

As labor nears, the increasing amounts of these hormones circulating in the body trigger the release of other contraction-stimulating substances like calcium and potassium in the uterine tissue. This biochemical cascade stimulates rhythmic contractions of the uterus.

What do contractions feel like?

The feeling of labor contractions varies significantly for each woman based on factors like the strength and position of her uterus, the baby’s size and position, and the progression of labor. However, most women describe the cramping sensation as:

  • Painful tightening in the lower abdomen that comes and goes
  • Feeling like the abdomen is being squeezed and drawn inward
  • Menstrual or premenstrual cramping but often more intense
  • Pain building up to a peak before fading away again
  • Radiating pain that wraps around to the lower back and thighs

During the early stages of labor when the cervix is starting to thin out (efface) and open up (dilate), contractions are usually mild and intermittent, occurring every 10-30 minutes and lasting 30-60 seconds. As labor progresses, the contractions become stronger, longer, and closer together.

Contraction patterns

Typical contraction patterns during active labor include:

  • Moderate labor: Contractions every 5 minutes, each lasting 60-90 seconds
  • Active labor: Contractions every 3 minutes, each lasting 60 seconds
  • Transition phase: Contractions every 2-3 minutes, lasting 60-90 seconds

Women often describe the peak of contractions as an extremely intense cramping and squeezing sensation. However, most report that the pain is manageable in between the peaks when the uterus relaxes again briefly.

How much do contractions hurt?

There is no universal pain scale that can quantify how much labor contractions hurt. Every woman experiences a different degree of pain that depends on multiple factors:

Individual pain threshold

Everyone has a different tolerance and threshold for coping with pain. While some women may be able to tolerate strong labor cramps, others with low pain tolerance may experience more pain even with milder contractions.

Size and position of baby

The intensity of labor cramps often depends on the size and position of the baby. Contractions tend to be more painful with a larger baby or an baby in an abnormal position as the uterus has to work harder to accommodate the baby. This can slow down or complicate labor.

Progression of labor

Early stage contractions are usually mild, but the pain progressively increases as the labor continues and the contractions become stronger and more frequent leading up to delivery.

Duration of labor

Women who experience prolonged labors lasting over 24 hours typically report experiencing more pain from the sustained contractions over an extended period.

Location of pain

Some women feel cramping primarily in the lower abdomen while others also experience intense back pain that radiates around the hips and thighs. The location of pain impact’s one perception of pain severity.

Use of pain relief

The amount of pain experienced can be significantly reduced by using medical pain relief such as epidurals, nitrous oxide gas, narcotics, etc. Women who give birth without pain medication often report very intense pain from contractions.

Preparation and positioning

Taking birthing classes, using breathing techniques, changing positions frequently, and having proper emotional support and reassurance can help manage the intensity of contraction pain during labor.

What does each stage of labor feel like?

Labor is divided into three stages, each marked by a different pattern and intensity of contractions:

First stage

This early phase, lasting up to 20 hours for first-time mothers, is characterized by light irregular contractions that become stronger and more frequent. Women may or may not feel these early contractions. As labor progresses, the contractions become very painful and occur every 2-5 minutes, lasting for 30-70 seconds.

Second stage

This active labor phase when the cervix fully dilates usually lasts up to 3 hours. Contractions occur every 1-2 minutes and last 60-90 seconds. Women describe feeling intense pressure in the pelvis and rectum. Uncontrolled pushing urges start towards the end of this stage.

Third stage

The final delivery stage lasts up to 30 minutes as the mother goes through the involuntary pushing and birth of the baby. Contractions may slow down but are still strong and painful during the final pushes. Cramping continues as the placenta detaches and is delivered.

What factors influence the pain of contractions?

While all labors involve painful contractions, some women experience more severe discomfort than others depending on these factors:

Size of baby

Larger babies put more pressure on the cervix and birth canal, intensifying the cramping needed to deliver the baby.

Baby’s position

Babies in an abnormal position like breech or posterior can cause more back pain and longer labors.

Shape of pelvis

Women with a narrower pelvic opening may experience more pain with contractions.

Strength of contractions

More frequent, longer-lasting and stronger contractions create more intense cramping.

Induction of labor

Contractions stimulated through medical induction with drugs like Pitocin are often more painful than natural contractions.

History of dysmenorrhea

Women who normally suffer from painful menstrual cramps may experience more severe contractions.

Stress and anxiety

High stress levels interfere with natural pain coping methods and make contractions feel worse.


Exhaustion from prolonged labor can lower pain tolerance.

Support system

Having an experienced birthing partner provides comfort and encouragement to manage contraction discomfort.

How are contractions monitored during labor?

During labor, contractions are monitored by the medical team to assess the progression and manage any complications. Some key aspects assessed are:


How often the contractions are occurring (every 2-10 minutes)


How long each contraction lasts (30-90+ seconds)


Assessed on a scale of 1-10 based on verbal feedback or observation

Resting tone

How relaxed the uterus feels between contractions

Fetal heart rate

Monitored for any distress correlated with contractions

Contraction Aspect Stage 1: Early Labor Stage 2: Active Labor Stage 3: Transition
Frequency Every 5-10 minutes Every 3-5 minutes Every 2-3 minutes
Duration 30-45 seconds 45-60 seconds 60-90 seconds
Intensity Mild Moderate-strong Very strong

Doctors or midwives may manually assess the strength, duration and frequency of contractions by feeling the abdomen or use technologies like tocodynamometry to automatically record contraction patterns.

Tips for coping with the pain of contractions

While painful contractions are an inevitable part of natural labor, there are techniques and preparations women can use to help manage the discomfort:

Take childbirth classes

Learning techniques like controlled breathing, visualization, and positioning can help cope.

Stay hydrated

Drink fluids regularly to prevent exhaustion and maintain energy.

Use focal points

Concentrate on objects, lights, or partner’s face during peaks.

Try different positions

Slow dancing, squatting, lunging, or using birth balls may provide relief.

Get massages

Massaging the lower back can help alleviate labor pains.

Take warm baths or showers

The warmth can have a soothing effect on the cramping sensation.

Use breathing techniques

Patterned breathing reduces tension, anxiety and perception of pain.

Listen to music

Soothing or uplifting music provides distraction.

Stay relaxed in between contractions

Remaining calm and limp in between contractions conserves energy.

When to seek medical help for contractions

While most contractions during labor are normal and expected, there are some warning signs that may indicate potential complications:

Contractions without cervical change

Strong regular contractions for over 2 hours without cervical dilation may signal failure to progress.

Excessively painful contractions

Extreme pain between contractions or that interferes with breathing may indicate issues like placental abruption.

Increasing contraction frequency

A sudden acceleration in contractions before 37 weeks may mean preterm labor.

Prolonged contractions

Each contraction lasting over 90 seconds can restrict oxygen supply to baby.

Irregular contractions

Sporadic timing between contractions may be a warning sign during late pregnancy.

Decreased fetal movement

If baby is not moving as expected, it may be a sign of fetal distress.

When to go to the hospital for labor

Timing hospital admission properly ensures you are checked in during active labor but not too early. Go to the hospital if:

  • Your water breaks
  • Contractions are under 5 minutes apart for 1-2 hours
  • You cannot talk through contractions anymore
  • You feel urge to push or bear down with contractions

Unless high-risk, avoid going too early to the hospital to prevent being sent home or undergoing unnecessary interventions.


While childbirth contractions can be very painful and stressful, understanding what to expect and using different coping techniques can help women manage the discomfort. Recognizing potential issues based on contraction patterns and getting to the hospital at the right time leads to the best delivery outcomes.
