When your water breaks, call your healthcare provider right away. That’s the single most important step. About 90% of people whose water breaks between 37 and 40 weeks will go into labor on their own within 24 hours, but your provider needs to know it’s happened so they can guide your next move based on your specific situation.
How to Tell If It’s Actually Your Water
Water breaking doesn’t always look like the dramatic gush you see in movies. Sometimes it’s a slow trickle that’s easy to confuse with urine, which leaks frequently in late pregnancy. Amniotic fluid is mostly clear or pale straw-yellow, and it has no smell. Urine, by contrast, has a distinct odor and a deeper yellow color. The other key difference: you can usually stop the flow of urine by squeezing your pelvic floor muscles, but you can’t control amniotic fluid.
If you’re not sure what you’re dealing with, put on a clean pair of underwear or a sanitary pad (not a tampon), lie down for 15 to 30 minutes, then stand up. Amniotic fluid pools while you’re lying down and comes out when you stand. Check the pad for color, amount, and smell. If the fluid is brown or green-tinged, that means your baby has passed their first stool, which your provider needs to know about immediately.
Your First Steps After Confirming It
Stay calm. Note the time it happened, the color of the fluid, and whether you notice any odor. Then call your provider. They’ll ask you these details and tell you whether to head to the hospital now or wait at home for contractions to start. Some providers will want you to come in right away, especially if you tested positive for group B strep during pregnancy or if the fluid looks anything other than clear or pale yellow.
Call immediately, rather than waiting, if you notice any of the following along with your water breaking:
- Fever
- Foul-smelling fluid
- Bright red bleeding (not just blood-tinged mucus)
- A sudden decrease in your baby’s movement
- Something you can see or feel in your vagina, which could indicate cord prolapse, a rare but serious emergency
What Not to Do
Once your water breaks, the protective barrier between your baby and the outside world is gone. Infection risk goes up with time, so everything you do from this point should focus on keeping bacteria out. The rules are straightforward:
- Don’t insert anything into your vagina. No tampons, no fingers checking for dilation, no sex.
- Don’t take a bath. Showers are fine, but sitting in water increases infection risk.
- Minimize internal exams. Even well-intentioned cervical checks push bacteria closer to the baby. These should wait until you’re in active labor.
Why Timing Matters
The longer the gap between your water breaking and delivery, the higher the chance of infection. Research comparing different approaches found that when labor was induced within 12 hours of the water breaking, the rate of a serious uterine infection called chorioamnionitis dropped nearly in half compared to a wait-and-see approach (about 5% versus 10%). Starting even sooner, within 6 hours, was linked to significantly lower antibiotic use and fewer signs of fetal distress.
This is why most providers lean toward getting labor started relatively quickly if contractions haven’t begun on their own. Your provider may offer you a window to let labor begin naturally, but current evidence supports induction sooner rather than later when your water breaks at term and contractions don’t follow. The specific timeline depends on your circumstances: how far along you are, whether you’re GBS positive, and how you and the baby are doing.
What to Expect at the Hospital
When you arrive, your provider will confirm that your membranes have ruptured. This usually involves a quick exam and sometimes a test of the fluid’s pH, since amniotic fluid is more alkaline than vaginal discharge. They’ll monitor your baby’s heart rate and check for signs of infection like fever or elevated heart rate in you.
If you’re already having regular contractions, labor will proceed on its own. If not, your provider will likely discuss induction options. This could start with medications to soften the cervix or with a synthetic version of the hormone that triggers contractions. The goal is to deliver your baby in a timeframe that keeps infection risk low while giving your body a chance to do much of the work naturally.
Preterm Water Breaking
If your water breaks before 37 weeks, the approach changes significantly. Your provider will weigh the risks of infection against the risks of delivering a premature baby. In many cases, the goal is to buy time for the baby’s lungs and other organs to mature, while closely monitoring for any signs of infection. This often means a hospital stay with continuous monitoring rather than immediate delivery. The earlier in pregnancy this happens, the more complex the decision-making becomes, and your care team will walk you through the options specific to your gestational age.
Packing and Practical Prep
Since only about 10% of labors begin with the water breaking (most start with contractions first), it can catch you off guard. Having your hospital bag packed by 36 weeks takes the scramble out of the moment. Keep a waterproof mattress pad on your bed in the final weeks, and consider keeping a towel in your car. These small preparations let you focus on the things that actually matter: noting the time, checking the fluid, and calling your provider.
