It's not always easy to know. If your water breaks, it could be a gush or a slow trickle of amniotic fluid. Rupture of membranes is the medical term for your water breaking. Let your doctor know the time your water breaks and any color or odor. Also, call your doctor if you think your water broke, but are not sure. An easy test can tell your doctor if the leaking fluid is urine (many pregnant women leak urine) or amniotic fluid. Often a woman will go into labor soon after her water breaks. When this doesn't happen, her doctor may want to induce (bring about) labor. This is because once your water breaks, your risk of getting an infection goes up as labor is delayed.
