Anticipation fills the air as you approach your due date. One of the most significant moments in your pregnancy journey can be when your water breaks. It’s a sign that labor is imminent and delivery is right around the corner.

When a pregnant person’s water breaks, it means the amniotic sac surrounding the baby has ruptured, allowing amniotic fluid to leak out through the vagina. The water breaking is also known as the rupture of the membranes. But not everyone’s water breaks. In some cases, your doctor will break your water during labor.

Unsure if your water has broken? Here’s what you need to know.

The Rupture of the Amniotic Sac

Inside your belly, your baby resides within the amniotic sac — a protective bubble filled with fluid. This sac serves multiple purposes: it cushions the umbilical cord, maintains a stable temperature, and provides a safe environment for your little one to grow.

For some pregnant people, the amniotic sac ruptures or breaks open when the body gears up for labor. After the amniotic sac ruptures, the fluid contained within it begins to drain through your vagina. This fluid is the “water”.

Does everyone’s water break naturally?

If you’re waiting impatiently for your water break, you’re not alone. While the popular image of water breaking involves a dramatic gush of fluid, the reality can be much different and less obvious.

Not every pregnant person experiences their water breaking before labor begins. When your water breaks before you experience signs of labor, it is known as a premature rupture of the membranes (PPROM.) According to StatPerls, this only occurs in about 8% of pregnancies.

For most, contractions kick off the labor process, and the amniotic sac ruptures later. It might rupture before you head to the hospital, at the hospital, or later in labor if your doctor intentionally breaks it.

For most, the water breaks during labor. Very rarely, in a premature delivery, you can give birth without ever breaking your water. This is called an en caul birth.

Signs Your Water Is About to Break

The anticipation of waiting for your water to break during pregnancy can be both exciting and nerve-wracking. Every twinge, cramp, or sensation can trigger a flurry of emotions as your due date approaches. It’s common to find yourself analyzing every movement, wondering if this is the time your labor will begin.

As you approach labor, paying attention to certain signs can help you anticipate when your water might break.

Here are five signs your water is about to break:

• Bloody discharge — A pinkish or brownish discharge (known as the “bloody show”) can occur as your body prepares for labor.

• Changes in discharge — Keep an eye on any changes in vaginal discharge. An increase in mucus-like discharge could be your mucus plug.

• Contractions — Regular, painful contractions that become more frequent and intense.

• Small leaks — Sometimes, your water breaks gradually, resulting in small leaks rather than a sudden gush.

• Increased pressure — You may feel increased pressure in your pelvic area as your baby descends into the birth canal.

What Causes Water to Break?

The amniotic sac can rupture due to contractions or the baby’s position. During the natural progression of labor, as your baby prepares for birth, their head may put pressure on the amniotic sac. This pressure may cause it to rupture.

Other factors may weaken the sac, leading to an earlier-than-expected break. If this happens before the 37th week of pregnancy, it’s termed preterm prelabor rupture of membranes (PPROM).

PPROM risk factors

When a pregnant person’s water breaks early, it’s known as PPROM. This occurs before the 37th week of pregnancy and can lead to complications such as infection, placental abruption, and umbilical cord issues.

If your water breaks unexpectedly, seek medical attention promptly to ensure your safety and your baby’s health. The exact trigger for PPROM isn’t always clear, but several factors may increase your risk of your water breaking early.

These include:

• Infection.
• Poor nutrition.

• Being underweight.
• Drug use.
• Previous PPROM.
• Smoking.

What Does Your Water Breaking Feel Like?

The sensation of your water breaking can be unique, varying from person to person. Some people describe it as a sudden gush of fluid, while others may feel a slow leak. Factors like the amount of amniotic fluid, the baby’s position, and individual sensitivity contribute to these differences.

Here’s what it might feel like for you:

• Gradual trickle — For some, water breaking isn’t a gush of fluid. It may feel more gradual — a slow trickle that feels like a persistent leak. It might remind you of a faucet dripping steadily.

• Pressure release — As the amniotic sac ruptures, you might experience a sense of pressure release. It’s like a balloon popping inside you.

• Small popping sensation — Some people hear or feel a small pop, almost like a bubble bursting. You’ll then feel the fluid escaping.
• Warm gush — Imagine suddenly feeling warmth in your lower abdomen or pelvic area. Some people describe it as a warm gush like you spilled a glass of water.

Everyone’s experience is different, and there is no one-size-fits-all description. Trust your instincts—if you suspect your water has broken, seek medical advice promptly.

Signs That Your Water Has Broken

When you’re wondering if your water has broken, here are some signs to look out for:

• Clear and odorless — Amniotic fluid is clear or pale yellow, thin, and odorless.
• Gush or subtle leak — Unlike dramatic movie scenes, water breaking doesn’t always result in a massive gush. Sometimes, it’s a gentle leak or stream, like pricking a balloon with a pin.
• Mucus or amniotic fluid? — As delivery approaches, the cervix softens, and you may lose your mucus plug. Sometimes, what appears to be water breaking is mucus. If the fluid is thicker, whiter, and odorless, it’s likely mucus.
• No urine smell — Unlike urine, amniotic fluid doesn’t smell like pee.
• You lose more fluid when you’re standing — Try standing up. Check to see whether there is an increase in fluid leakage when you’re standing upright. If more fluid comes out when you’re standing instead of sitting, this is a sign that your water has broken.
• Fluid comes out during a contraction — If you feel fluid coming out while your uterus tightens, it’s probably amniotic fluid, and your water has broken.

Water Breaking vs. Vaginal Discharge: What’s the Difference?

It’s crucial to distinguish between water breaking and normal vaginal discharge. Discharge is typically odorless and varies in consistency, while amniotic fluid may feel like a sudden gush or leak of clear or pale yellow fluid.

Understanding the distinction between water breaking and vaginal discharge is crucial during pregnancy:

Water breaking

When the amniotic sac tears, releasing amniotic fluid through the vagina. A sign that labor is imminent.

Signs of water breaking include:

• A sudden gush or trickle of fluid.
• Clear or pale yellow color.
• May occur during a contraction or spontaneously.

Vaginal discharge

Vaginal discharge is a normal occurrence during pregnancy and throughout life.

Signs of vaginal discharge include:

• Thin, white discharge. Or mucus streaked with blood (pink or brown).
• May be odorless.
• Occurs intermittently.

How Long Until You Have to Deliver?

If you think your water has broken, seek medical attention immediately. Delaying an evaluation can lead to infections or other health issues.

In most cases, labor begins within 24 hours of the water breaking. Approximately two-thirds of pregnant people enter labor within this time frame after their water breaks.

If labor doesn’t start on its own, your doctor may give you drugs to bring on labor. They may also give you antibiotics to protect against infection.

When to Talk to Your Doctor

If you suspect your water has broken, contact your care team immediately. Your care team will guide you through the next steps to ensure a safe and healthy delivery. It won’t be long before you meet your bundle of joy.
