One of the most common reasons for a visit to the emergency room during pregnancy is to determine whether your water bag has broken. It’s completely normal to wonder, “Did my water just break?” Let’s walk through what that means, how to tell if it may have happened, and what to do next. If you’re ever unsure, call your obstetrician or midwife.

What does “water breaking” mean?

Your baby is surrounded by amniotic fluid inside a balloon-like protective sac. When the membranes rupture—partially or fully—fluid can leak out; this is commonly called your “water breaking.” Clinically, it’s termed premature rupture of membranes (PROM) when it occurs before contractions begin or preterm premature rupture of membranes (PPROM) when it occurs before you reach full term in your pregnancy. There are different ways to say your water bag has broken. You may also hear the term “membrane rupture.” Both terms have the same meaning.

For reference, you are full term once you are within 3 weeks of your due date. Your due date is at 40 weeks of pregnancy, so full term is 37 weeks or greater.

How might it feel or look?

Movies often portray your water bag breaking as an obvious, dramatic event. That portrayal is for entertainment purposes and may not always reflect reality.

You may notice a gush of fluid from the vagina or a slow, steady trickle that keeps dampening your underwear or pad.

Amniotic fluid is usually clear or pale straw-colored. It does not have an odor, unlike urine which smells like…well, urine. Urine also tends to be more yellow, though it can be clear if you have been drinking lots of water.

Sometimes, after a shower or urinating, you may experience fluid leakage from the vagina. This could be your water bag breaking. But it can also be a release of a pocket of fluid from the vagina or bladder.

If you are unsure if your water has broken, change to a fresh pad or pantiliner. If wetness persists, it’s time to go in for an evaluation to determine if your water bag is indeed broken.

Why it matters

After the membranes rupture, labor often follows on its own, especially if your pregnancy is full-term. The balloon that houses your baby and amniotic fluid helps to protect you and your baby from infection. Once that balloon breaks, your risk of infection increases. In full-term pregnancies, it is best to have your baby as soon as possible after your water bag has broken. This is to help reduce the risk of infection.

If rupture happens preterm, your team balances the benefits of continuing pregnancy against the risks of infection and complications for you and your baby.

What to do right away if you think your water broke

• Put on a pad (not a tampon). This helps you see the amount and color of fluid.
• Notice color and smell. Clear or faintly sweet fluid suggests amniotic fluid; yellow, stronger-smelling fluid may be urine.
• Avoid vaginal insertion (no tampons or sex). You do not want to introduce infection into that area by inserting anything into the vagina.
• Call your physician or certified nurse midwife. Be ready to describe gush vs. leak, color/odor, weeks pregnant, and whether you have contractions, bleeding, fever, or decreased baby movement.

Tests to check if you have broken your water

Your clinician may perform a sterile speculum exam to look for amniotic fluid pooling or leakage from the cervix.

They may collect fluid on a small swab and place it on a strip of paper to test the pH. This strip of paper is called a nitrazine test. More commonly, they may perform a more sophisticated test that looks for proteins present in amniotic fluid (amnisure).

Ultrasound may also be performed. This will check to see how much amniotic fluid surrounds the baby. If your water bag has broken, your fluid level, also called AFI (amniotic fluid index), may be decreased.

What happens next depends on gestational age

At term (≥37 weeks), you will likely go into labor soon after rupture; if not, your team may discuss inducing labor to reduce infection risk while keeping you and baby safe.

Between 34 and 36 6/7 weeks, your doctor will likely also induce your labor, as the benefit of delivery will usually outweigh the risk of infection with continued pregnancy.

Before 34 weeks, the aim is often to continue the pregnancy safely and wait to deliver. You may need to be admitted to the hospital and given antibiotics to reduce the risk of infection and preterm delivery. Your team will also discuss measures to help the baby in case you are delivered preterm, such as giving you antenatal corticosteroids to reduce the risks to the baby at birth.

When to seek emergency care

Go to the hospital or call your physician immediately if:

-fluid is green or yellow, as this may indicate that the baby is under stress.

-you have a fever or foul-smelling amniotic fluid, as this may indicate a possible infection.

-contractions or decreased fetal movement.

-vaginal bleeding.

-sudden large gush, as this can cause a surgical emergency known as umbilical cord prolapse or placental abruption.

Summary

Finally, if you are not sure what exactly is going on, reach out to your doctor. It’s okay to be unsure—calling your provider for advice is exactly the right step. You know your body best; your care team is there to guide and support you so you and your baby stay safe throughout your pregnancy.

Terms to know

SROM(spontaneous rupture of membranes)- you are full term (37 weeks or more pregnant), your water has broken, and you are feeling contractions.

PROM (premature rupture of membranes)—your water has broken, you are full term, and you are not feeling contractions.

PPROM (preterm premature rupture of membranes)- you are preterm (less than 37 weeks pregnant)  and your water has broken.

AROM (artificial rupture of membranes)-your physician or midwife intentionally broke your water bag.
