Causes of water breaking early in pregnancy

Possible contributors include infection around the pregnancy, bleeding during pregnancy, an overstretched uterus from more than one baby or excess amniotic fluid, cervical problems, smoking, and a previous early membrane rupture. These factors raise concern but do not prove why it happened in an individual pregnancy.

The waters are the fluid inside the amniotic sac surrounding the baby. Rupture before labour begins is called premature rupture of membranes; when it happens before the pregnancy reaches term, clinicians may call it preterm premature rupture of membranes.

Fluid may come as a gush or a continuing watery trickle that cannot be controlled like urine. Discharge and urine leakage can feel similar, so a maternity team may examine you, test the fluid, check your temperature, and assess the baby's heartbeat.

Contact your maternity unit promptly if you think your waters have broken, even without contractions. Note when leaking began and the fluid's colour, smell, and approximate amount. Wear a sanitary pad so the fluid can be assessed; do not insert a tampon or have sex while awaiting advice.

Management depends on gestational age, labour, infection signs, the baby's wellbeing, and fluid findings. It may include monitoring, medicines to reduce infection risk, an antenatal steroid injection to support the baby's preparation for birth, or planning birth when continuing the pregnancy is less safe.

Go to maternity emergency care now for green, brown, bloody, or foul-smelling fluid; fever or chills; severe abdominal pain; regular painful contractions; vaginal bleeding; reduced baby movement; or anything visible or felt in the vagina. Call emergency services if you feel faint, collapse, or cannot travel safely.

Ask whether testing confirms amniotic fluid, how the baby will be monitored, whether infection is suspected, and which changes should bring you back immediately. You can also ask how gestational age affects the balance between waiting and birth, and whether medicines or induction of labour may be considered.
