How early can Braxton Hicks start?

A Braxton Hicks contraction is a temporary tightening of the womb. The abdomen may feel firm, then soften as the tightening passes. These contractions are usually irregular and do not steadily become closer, longer or stronger. They may be more noticeable after activity, when you are tired, when your bladder is full or when you have not had enough fluids.

Feeling tightening does not by itself show whether labour has started. The pattern, associated symptoms and stage of pregnancy matter. Contractions before labour can be difficult to distinguish from early labour, particularly when they continue despite rest or become rhythmic.

Pause, change position and rest. Drink fluids if you have been advised that this is suitable for you, and empty your bladder. Notice when each tightening starts, how long it lasts and whether the gaps change. Gentle breathing can help you stay comfortable. Do not rely on timing alone if you also have fluid leakage, bleeding, pelvic pressure or unusual backache.

Contact your maternity team promptly if tightenings become regular, painful or progressively stronger, especially earlier in pregnancy. Seek urgent assessment for vaginal bleeding, fluid leaking, reduced fetal movement, severe abdominal or back pain, fever or strong pelvic pressure. These features can indicate a problem such as preterm labour and need assessment rather than home observation.

Ask how your maternity service wants you to time contractions, which symptoms require an immediate call and what comfort measures are appropriate for your pregnancy. Keep the contact number available if the pattern changes.
