During pregnancy, your uterus tightens and relaxes as it prepares for delivery. These tightenings are called contractions, and they can start well before your baby is ready to be born. Some are just practice. Others are true labor contractions. Knowing the difference between Braxton Hicks contractions and true labor can help you feel more confident as your due date approaches and help you decide when to call your OB.
What Are Braxton Hicks Contractions?
Braxton Hicks contractions are sometimes called “practice contractions” because they help your uterus prepare for labor without actually starting it. Most women describe them as a tightening or hardening across the belly that comes and goes. Some feel mild pressure or squeezing that is uncomfortable but not steadily painful.
These contractions show up more often in the third trimester, but some women notice them earlier. They are usually irregular, meaning you might feel a few close together and then none for hours. Common triggers include dehydration, physical activity, a full bladder, or a busy day without enough rest. If you drink water, change your position, or rest on your left side, they will often slow down or stop.
What Do True Labor Contractions Feel Like?
True labor contractions are more regular, more intense, and closer together over time. Many women describe them as a wave that builds to a peak and then eases off. Early contractions may feel like strong menstrual cramps or lower back pain. As labor progresses, contractions often become harder to talk through.
The key difference is that true labor contractions cause the cervix to soften, thin out, and dilate. Braxton Hicks do not usually cause meaningful cervical change. You cannot check your cervix at home, which is why paying attention to the pattern of your contractions is so important. Regular prenatal care visits can help your provider track cervical changes and keep you informed about what to expect as delivery gets closer.
Pattern, Not Pain, Is What Matters Most
It is possible for Braxton Hicks to feel uncomfortable, and it is possible for early labor to feel mild. So instead of focusing only on how strong a contraction feels, you will be better informed if you pay attention to the timing pattern of contractions over time.
Braxton Hicks contractions tend to be irregular and often stop with rest or hydration. True labor contractions become more regular, last longer, come closer together, and build in intensity. They keep going even if you change positions or lie down. Ask yourself one simple question: Are these getting more regular and more intense over time? If yes, and that trend has continued for at least an hour or two, that is a meaningful sign.
