How to tell the difference between false alarms and the real thing.
In the final weeks of pregnancy, every twinge raises the same question: is this it? Distinguishing true labor from the practice contractions and false alarms that precede it is one of the most useful things you can learn before your due date. This guide — aligned with ACOG guidance and reviewed by our medical reviewer — covers the real signs of labor, how to tell them from false labor, the 5-1-1 rule, and the symptoms that mean call now.
The clearest tell is pattern and progression. True labor contractions come at regular intervals that get closer together, last longer, and grow stronger over time — and crucially, they keep going whether you rest, walk, hydrate, or change position. False labor (Braxton Hicks) is irregular, does not build, often centers in the front, and typically eases when you move or rest. If a glass of water, a position change, and an hour make the contractions fade, it was likely practice.
A widely used benchmark for heading to the hospital in a full-term, low-risk pregnancy is 5-1-1: contractions about five minutes apart, each lasting about one minute, sustained for at least one hour. It is a guide, not a law — your provider may tell you 4-1-1, or to come in earlier if this is not your first baby (labor can move faster) or if you live far from the hospital. Always follow your own provider’s instructions over a general rule.
Your water breaking can be a dramatic gush or a slow trickle. Note the time, color, and smell, then call your provider — even if contractions have not begun. Clear or pale fluid is normal; green or brown fluid (possible meconium), a foul odor, or heavy bleeding needs prompt attention. Most people begin labor within about 24 hours of membranes rupturing, and your provider will advise on next steps based on your specific situation.
Several signs hint that labor is approaching, sometimes days ahead: the "bloody show" or loss of the mucus plug (pink- or brown-tinged discharge as the cervix softens), lightening (the baby dropping lower, easing breathing but increasing pelvic pressure), persistent low back ache, loose stools, and a burst of nesting energy. These suggest progress but do not, on their own, mean active labor has started.
Some symptoms override any rule. Call right away for: signs of labor before 37 weeks (preterm labor), heavy or bright-red vaginal bleeding, your water breaking with green/brown or foul-smelling fluid, a noticeable decrease in your baby’s movements, severe or constant abdominal pain, or a severe headache, vision changes, or sudden swelling (possible preeclampsia). You will never be faulted for calling — triage lines exist precisely for these judgment calls.
Early labor — the cervix opening to roughly six centimeters — is usually the longest, most variable phase and is often best spent at home: rest while you can, eat lightly, hydrate, take a warm shower, and time contractions. Conserving energy here pays off later. As contractions reach your provider’s threshold and you can no longer talk through them, it is time to go in.
True labor builds and will not quit; false labor fades with rest. Use 5-1-1 as a starting guide but defer to your provider’s instructions, call right away if your water breaks or anything feels wrong, and trust that early labor is usually a "stay home and rest" phase. When in doubt, make the call.
Real (true) labor contractions come at regular intervals that get progressively closer, last longer, and feel stronger over time, and they continue regardless of whether you rest, walk, or change position. False labor (Braxton Hicks) is irregular, does not intensify, and usually eases when you move, hydrate, or rest.
A widely used guide for when to head to the hospital with a full-term, low-risk pregnancy: contractions about 5 minutes apart, each lasting around 1 minute, sustained for at least 1 hour. Always follow your own provider’s specific instructions, which may differ (for example, 4-1-1, or come in sooner for a second baby).
Note the time, color, and odor of the fluid and call your provider, even if contractions have not started. Clear or pale fluid is typical; green, brown, or foul-smelling fluid, or heavy bleeding, needs immediate attention. Most people go into labor within 24 hours of their water breaking.
Yes. Losing the mucus plug or seeing a "bloody show" (pink- or brown-tinged mucus) means the cervix is changing, but labor can still be hours or days away. It is a sign things are progressing, not a signal to rush in by itself.
Call immediately for signs of preterm labor before 37 weeks, heavy or bright-red bleeding, your water breaking with green or foul fluid, decreased fetal movement, severe constant abdominal pain, or severe headache/vision changes/sudden swelling (possible preeclampsia). When unsure, call — that is what the line is for.
Early labor (cervix dilating to about 6 cm) is the longest and most variable phase — often many hours, especially for a first baby. It is usually best spent at home resting, hydrating, and timing contractions until they reach your provider’s "come in" threshold.
