How to Know If Your Water Has Broken
The short answer
When your water breaks, the amniotic sac surrounding your baby ruptures, releasing amniotic fluid. This can be a dramatic gush or a slow, steady trickle. Amniotic fluid is typically clear, pale yellow, or slightly pink, and is odorless or mildly sweet-smelling (not like urine). If you think your water may have broken, contact your provider.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Your water usually breaks during or just before labor begins, typically at or near your due date. Only about 10-15% of labors begin with the water breaking before contractions start. Amniotic fluid differs from urine in that it is continuous (you cannot stop it by squeezing pelvic muscles), odorless, and clear. If you are unsure, wear a pad and note the color, amount, and smell, then call your provider.
Once your water breaks at term, labor usually begins within 12-24 hours if it has not already started. Your provider will want to know the time it broke, the color of the fluid (green or brown fluid could indicate meconium), and whether you feel the baby moving. Avoid baths or inserting anything into the vagina after your water breaks to reduce infection risk.
What Should You Do?
When to take action
- Clear or pale yellow fluid with no strong odor after 37 weeks
- Water breaks and contractions follow within hours
- Baby continues to move normally after water breaks
- You think your water may have broken but are not sure (slow trickle vs discharge)
- Your water breaks but contractions have not started yet
- You want guidance on when to go to the hospital
- Water breaks before 37 weeks (preterm premature rupture of membranes)
- Amniotic fluid is green, brown, or has a foul smell, suggesting meconium or infection
- Water breaks and you feel the umbilical cord in your vagina (cord prolapse - call 911)
- Baby is not moving normally after water breaks

Related Maternal Concerns
Premature Rupture of Membranes (PROM/PPROM)
Premature rupture of membranes (PROM) occurs when the amniotic sac breaks before labor begins. When this happens before 37 weeks, it is called preterm premature rupture of membranes (PPROM) and requires immediate medical attention. PPROM affects about 3% of pregnancies and is a leading cause of preterm birth.
Losing Mucus Plug and Bloody Show Before Labor
The mucus plug is a thick collection of mucus that seals the cervical opening during pregnancy to protect against infection. Losing the mucus plug (which may be accompanied by a bloody show - mucus tinged with pink or brown blood) is a sign that your cervix is beginning to dilate in preparation for labor. It can happen days to weeks before labor begins.
Braxton Hicks vs Real Contractions
Braxton Hicks contractions are irregular, usually painless "practice" contractions that help your uterus prepare for labor. Unlike real labor contractions, they do not increase in frequency, intensity, or duration over time, and they typically stop with rest, hydration, or a change in activity.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
