Waters breaking: what to expect

Your “waters” are the bag of amniotic fluid that surrounds and protects your baby, and when it breaks, that fluid is released. Films make it look like a sudden dramatic gush in public, but in reality it’s often more subtle — and, importantly, only a minority of labours actually start this way. For most people, contractions come first and the waters break later, sometimes not until well into labour.

What it feels like. It can be anything from a sudden gush to a slow, uncontrollable trickle that keeps coming (unlike a small wee, which stops). You might feel a little “pop” first. It can be hard to tell from urine or the increased discharge of late pregnancy — the giveaways are that amniotic fluid keeps leaking and you can’t hold it back, and it’s usually pale and mild-smelling.

What to do. Note the time it happened and the colour of the fluid, and pop on a pad (not a tampon) so you can keep an eye on it. Then contact your midwife or maternity unit — even if you’re not having contractions — so they can advise you on what to do next based on your situation.

Colour matters. Clear or pale straw-coloured fluid is normal. But if the fluid is green, brown or bloody, call your maternity unit straight away, as green or brown can mean your baby has done their first poo (meconium) and needs checking. A small amount of blood-tinged mucus (a “show”) is different and can be a normal sign labour is near.

If labour doesn’t start on its own. Often labour follows within hours of the waters breaking. If it doesn’t, your team will talk with you about options, because once the waters have gone there’s a slightly increased risk of infection over time. Depending on how many weeks you are and your circumstances, they may recommend waiting a little longer with monitoring, or inducing labour. They’ll also advise you to watch for signs of infection and to keep track of your baby’s movements.

If it happens before 37 weeks. Waters breaking early (preterm) needs prompt attention, so call your maternity unit or go in immediately — you’ll be assessed, and your team will make a plan to protect you and your baby, which may include medication and closer monitoring. Don’t wait to see what happens.

A few practical tips. Once your waters have broken, avoid putting anything in the vagina (no baths with bath products designed to go inside, no sex, no tampons) to reduce infection risk — showers are fine — and follow your midwife’s advice. Keep an eye out for a fever, tummy pain, or fluid that starts to smell offensive, and report a change in your baby’s movements at once.

Not sure if it’s your waters? It can genuinely be hard to tell from a leak of urine (common in late pregnancy) or normal discharge. If you’re unsure, pop on a pad, lie down for half an hour, then stand up — a gush as you stand often points to waters. Either way, if you think it might be your waters, it’s always fine to call your maternity unit and ask; they can check with a simple examination if needed, and would much rather you rang.

How much fluid should there be? It varies a lot — some people have a dramatic gush, others a slow trickle that keeps refreshing — and it can keep leaking in smaller amounts right up to the birth, because your baby continuously makes more amniotic fluid. So you don’t need to worry that “it’s all gone” or that your baby has no cushioning left; there’s still plenty around them.

The bottom line: if you think your waters have broken, note the time and colour and call your maternity unit — day or night — for advice. Green or brown fluid, bleeding, waters before 37 weeks, or reduced movements all mean call immediately. Otherwise, it’s often the exciting sign that you’ll be meeting your baby before too long.
