For most pregnancies, the right time to head to the hospital is when your contractions are 5 minutes apart, each one lasts about 1 minute, and that pattern has held steady for at least 1 hour. This is known as the 5-1-1 rule, and it’s the standard guideline most providers give. But several situations call for going in sooner, and knowing the difference between “keep timing” and “go now” can save you unnecessary trips or dangerous delays.
The 5-1-1 Rule
The numbers are simple: contractions every 5 minutes, lasting 1 minute each, for 1 hour straight. When all three criteria are met, you’re likely in active labor and it’s time to go. Hospitals generally admit patients once they reach 4 to 6 centimeters of cervical dilation with regular, strong contractions. Arriving too early, while you’re still in the latent (early) phase, is associated with higher rates of medical intervention, so timing your arrival well is worth the effort.
To use the rule, start a timer at the beginning of one contraction and note when the next one starts. That gap is your frequency. Then time how long a single contraction lasts from start to finish. Write it down or use a contraction-timing app. You’re looking for a consistent, predictable rhythm that doesn’t fade when you change what you’re doing.
True Contractions vs. Braxton Hicks
Braxton Hicks contractions can fool you, especially in the final weeks. Three differences help you tell them apart. First, true labor contractions follow a regular pattern and get progressively stronger and closer together. Braxton Hicks stay irregular. Second, Braxton Hicks typically last less than 30 seconds and feel uncomfortable but rarely painful, while true contractions last 30 to 70 seconds and intensify over time. Third, true contractions keep going no matter what you do. If the tightening stops when you walk around, rest, or shift positions, it’s almost certainly false labor.
If you’re unsure, try drinking a large glass of water, lying on your side, and resting for 30 minutes. Braxton Hicks often fade with hydration and rest. Real labor won’t.
Go Immediately If Your Water Breaks
If you feel a gush or a steady trickle of fluid from your vagina, head to the hospital for evaluation even if you’re not having contractions yet. Ruptured membranes need to be confirmed because a delayed diagnosis raises the risk of infection. Once your water breaks at full term, 60% to 70% of women will go into spontaneous labor within 24 hours, and over 95% within 72 hours, but your provider needs to assess you before you wait it out at home.
Pay attention to the fluid itself. Normal amniotic fluid is clear or pale yellow and mostly odorless. Fluid that looks green or brown could contain meconium (the baby’s first stool), which signals the baby may be in distress. Fluid that smells foul could indicate infection. Either warrants urgent evaluation. One of the most significant risks after membranes rupture is infection inside the uterus, so noting the time your water broke, the volume, and the color helps your care team act quickly.
Bleeding: Normal vs. Dangerous
Late in pregnancy, losing your mucus plug or having a “bloody show” is a normal sign that your cervix is preparing for labor. This looks like a small amount of pink, brown, or blood-tinged mucus, usually no more than a tablespoon or two. It can appear days before labor starts or right as contractions begin.
What’s not normal is heavy bleeding. If you’re soaking through a pad, passing clots larger than an egg, or bleeding bright red like a period, that could point to a serious complication like placental abruption. Go to the hospital right away. If you’re unsure whether what you’re seeing is bloody show or something more concerning, or if you’re earlier than 37 weeks, call your provider rather than waiting to see what happens next.
Emergency Warning Signs
Some situations require an immediate trip to the hospital regardless of where you are in labor. These include:
- A noticeable change in your baby’s movement. There’s no magic number of kicks that counts as “normal,” but a clear decrease or stop in movement from what you’ve been feeling is what matters. If your baby seems unusually still, don’t wait.
- Severe headache that won’t go away. Combined with blurred vision, light sensitivity, or seeing spots, this can signal preeclampsia, a dangerous blood pressure condition.
- Vision changes. Temporary loss of vision, sudden blurriness, or light sensitivity during pregnancy are red flags.
- Severe belly pain. Persistent, intense abdominal pain that’s different from contractions could indicate placental problems or other complications.
- Severe shortness of breath. Mild breathlessness is common in late pregnancy, but struggling to breathe is not.
- Nausea or vomiting with headache or high blood pressure symptoms. This combination points toward preeclampsia rather than a stomach bug.
Any of these symptoms warrants going to the emergency room, not waiting for a callback from your provider’s office.
If You’re GBS Positive
About 1 in 4 pregnant women carry Group B Streptococcus bacteria, which is harmless to you but can cause serious infection in a newborn. If your test came back positive (usually screened around 36 weeks), you’ll receive IV antibiotics once labor starts. The antibiotics work best when given during labor with enough time before delivery, so let your provider know as soon as you think labor is beginning. Follow whatever specific timing instructions your provider gave you, which may mean heading in a bit earlier than the standard 5-1-1 guideline. If you’re allergic to penicillin, make sure your care team knows before you arrive.
Adjust for Your Travel Time and History
The 5-1-1 rule assumes you live a reasonable distance from the hospital. If you’re 45 minutes or more away, you’ll want to leave earlier in the process. Research shows that women who know they face a longer journey tend to adjust when they depart, and that’s smart. A contraction pattern of every 7 to 8 minutes that’s clearly intensifying may be your cue if you have a long drive ahead.
Your labor history matters too. First labors tend to be longer, often giving you more time at home. Second and subsequent labors frequently progress faster, sometimes dramatically so. If your previous labor moved quickly, plan to leave sooner this time. The same applies if you’ve been told you have any risk factors for rapid labor.
Have your hospital bag packed and your route planned by 37 weeks. Know which entrance to use after hours, where to park, and who’s on your emergency contact list for childcare or transportation. The less you have to figure out during contractions, the calmer your trip will be.
