When to worry about waters breaking with preterm labour

Waters breaking means the membranes around the baby may have opened, allowing amniotic fluid to leak. Preterm labour occurs before the pregnancy reaches term, and waters breaking is a common presentation of Preterm Labour. Leakage may be a gush, a steady trickle, or dampness that returns after changing position. Fluid can be difficult to distinguish from urine or normal discharge at home.

A maternity team can examine the fluid, check your temperature and pulse, assess contractions, and monitor you and the baby. They may also assess for infection or cervical change. Do not insert anything into the vagina while waiting for advice.

Contact your maternity unit or emergency service immediately and explain that you may be leaking fluid before term. Note when the leakage began, its colour and smell, and whether it is continuous. Use a clean sanitary pad rather than a tampon, and take the pad with you if requested. Avoid sex, swimming, and placing medicines or other products in the vagina until assessed.

Keep your pregnancy notes and medication list available. If you feel faint, have severe pain, or cannot travel safely, call emergency services. Do not drive yourself if you feel unwell.

Seek urgent care straight away for fever or chills, worsening abdominal or back pain, regular tightening, vaginal bleeding, green or foul-smelling fluid, reduced baby movements, or feeling seriously unwell. These signs can need rapid treatment, but their absence does not make suspected membrane rupture safe to watch at home. Get assessed even if the leak stops.

Ask whether the membranes have ruptured, how the baby and cervix will be monitored, and which symptoms should prompt a return. You can also ask about infection precautions, medicines that may be considered, and what activity is appropriate while you are being observed.
