What Should You Know About Water Breaking While Sleeping?

You may notice a damp patch, a sudden gush when standing, or repeated trickling after getting up. Amniotic fluid is usually clear or pale and watery, but it can be difficult to distinguish from urine or discharge after lying down. A clean pad can help you observe the fluid; it cannot confirm the diagnosis. A leak may happen before contractions begin. If it occurs before full term, it can be associated with preterm labour and needs prompt review.

Stay calm, put on a clean maternity pad and note the time you first noticed wetness. Check the fluid’s colour and whether it continues to leak. Avoid tampons, sex, swimming and inserting anything into the vagina. Call your maternity unit or obstetric team promptly for instructions, and take your pregnancy notes if you are asked to attend. Keep track of baby movements while arranging care.

Go to urgent maternity care for green or brown fluid, bleeding, fever, severe pain, regular contractions, reduced baby movements or feeling faint or very unwell. Contact the team immediately if you are not yet full term, even without pain; see [Preterm Labour](/conditions/preterm-labour/) for related information. Do not wait until morning to report suspected ruptured membranes.

Ask how the team will check whether your waters have broken, whether you need monitoring, and what bathing, activity and sex advice applies. Ask when to check your temperature and movements, and who to call if leaking continues after you return home.
