When Do Braxton Hicks Contractions Start?

These practice contractions are tightenings of the womb that can come and go without settling into a regular pattern. The abdomen may feel firm, then relax. They are often uncomfortable rather than steadily painful, and they do not normally become closer, longer, and stronger in a predictable sequence. Activity, a full bladder, dehydration, or changing position can make them more noticeable. The timing alone cannot confirm whether labour has started.

Pause and notice when each tightening begins and ends. Drink water, empty your bladder, rest, or change position, then see whether the pattern settles. Gentle movement may feel helpful for some people, while quiet rest suits others. Keep your maternity unit's contact details available and follow any personalised advice from your midwife or obstetrician.

Contact your maternity team promptly if tightenings become regular or painful, do not ease with rest, or occur with leaking fluid, vaginal bleeding, pelvic pressure, unusual backache, or reduced fetal movement. If these symptoms happen before your care team considers your pregnancy full term, urgent assessment is needed because contractions can be a sign of [Preterm Labour](/conditions/preterm-labour/).

Ask when your team wants you to call, how to time contractions, and which symptoms should take you directly to the maternity unit. You can also ask whether your pregnancy has any features that change the advice about early tightenings.
