Your health matters just as much as your baby's. If you are dealing with premature rupture of membranes (prom/pprom), here is what you need to know.
The short answer
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.
Key takeaways
- 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.
- Usually normal when: At term (after 37 weeks), water breaking before contractions start is a normal variation of how labor can begin
- Call your doctor if: Any sudden gush or persistent trickle of fluid from the vagina before 37 weeks - go to the hospital immediately
- Varies by age — see the age-by-age breakdown below
“About 1 in 8 women experience symptoms of postpartum depression. If you have symptoms of depression that last longer than 2 weeks, tell your health care provider.”
Thousands of parents search for this exact thing. You are not alone.
What Parents Should Know
According to ACOG, NIH, March of Dimes guidelines, 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. At Second trimester, pPROM before 24 weeks (previable PPROM) is rare but serious. Treatment depends on gestational age and individual circumstances. Your medical team will discuss all options with you compassionately. If you notice fluid leaking at any point in the second trimester, go to the hospital immediately for evaluation. It is generally considered normal when at term (after 37 weeks), water breaking before contractions start is a normal variation of how labor can begin. However, you should contact your pediatrician promptly if any sudden gush or persistent trickle of fluid from the vagina before 37 weeks - go to the hospital immediately.
Normal vs. Concerning
By Age
What to expect by age
Second trimester
PPROM before 24 weeks (previable PPROM) is rare but serious. Treatment depends on gestational age and individual circumstances. Your medical team will discuss all options with you compassionately. If you notice fluid leaking at any point in the second trimester, go to the hospital immediately for evaluation.
Third trimester
PPROM between 24-37 weeks requires hospitalization. Management often includes antibiotics to prevent infection, corticosteroids to mature the baby's lungs, and close monitoring. The goal is to safely prolong pregnancy while balancing the risks of infection and prematurity. At or near 34 weeks, delivery may be recommended.
Labor & delivery
PROM at term (after 37 weeks) occurs in about 8% of pregnancies. If labor does not begin within 12-24 hours, induction is usually recommended to reduce infection risk. Your provider will monitor for signs of infection and fetal well-being. Most babies do well after term PROM.
What to Tell Your Pediatrician
- Describe when you first noticed premature rupture of membranes (prom/pprom) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if you think you may be leaking small amounts of fluid but are not sure.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- At term (after 37 weeks), water breaking before contractions start is a normal variation of how labor can begin
- You think you may be leaking small amounts of fluid but are not sure
- Any sudden gush or persistent trickle of fluid from the vagina before 37 weeks - go to the hospital immediately
- Fluid leaking with fever, foul-smelling discharge, or abdominal tenderness
- Water breaks and fluid is green, brown, or bloody
- You feel the umbilical cord at the vaginal opening - call 911, get on hands and knees
What You Can Do at Home
- Keep track of when you notice premature rupture of membranes (prom/pprom) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that at term (after 37 weeks), water breaking before contractions start is a normal variation of how labor can begin — this is generally within the range of normal.
- At Second trimester, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Prioritize your own rest and nutrition. Accept help when offered, and do not hesitate to reach out to your healthcare provider.
- While monitoring at home, seek immediate care if any sudden gush or persistent trickle of fluid from the vagina before 37 weeks - go to the hospital immediately.
Related Conditions
How to Know If Your Water Has Broken
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.
Preterm Labor Signs
Preterm labor is labor that begins before 37 weeks of pregnancy and affects about 10% of pregnancies. Recognizing the signs early is critical because treatment can often delay delivery, giving the baby more time to develop. Signs include regular contractions, lower back pain, pelvic pressure, vaginal discharge changes, and fluid leaking. Contact your provider immediately if you suspect preterm labor.

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.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
