When Do Braxton Hicks Contractions Start in Pregnancy?

A practice contraction is a temporary tightening of the womb. Your abdomen may become firm and then relax. The sensations can be mild, uncomfortable, or barely noticeable. They commonly vary in spacing and intensity rather than building in a steady rhythm. Walking, a busy day, dehydration, a full bladder, or a change in position can make them stand out. The point at which you first notice them differs from person to person and does not by itself indicate that birth is near.

Take a break, drink water, empty your bladder, and change position. Time a series of tightenings if they continue, recording their spacing, duration, and strength. Notice your baby's usual movements. If symptoms persist or you feel uncertain, contact your maternity team and describe the pattern rather than waiting for it to become severe.

Contact maternity care promptly if contractions become regular, stronger, or painful, or if they continue after rest and fluids. Seek urgent advice for vaginal bleeding, leaking fluid, persistent pelvic pressure, ongoing lower-back pain, or reduced fetal movement. When these signs occur before full term, clinicians need to assess for possible [Preterm Labour](/conditions/preterm-labour/).

Ask your obstetrician or midwife when to start timing contractions, which number to call day or night, and how your pregnancy history affects the plan. Confirm where you should go if symptoms occur with bleeding, fluid loss, or reduced movement.
