The 5-1-1 Rule

Go to the hospital when contractions follow the 5-1-1 pattern: 5 minutes apart, lasting 1 minute each, for at least 1 hour. This pattern indicates active labor. Time contractions from the start of one to the start of the next. True labor contractions get progressively closer together, longer in duration, and stronger over time. Braxton Hicks (false labor) are irregular and do not follow a progressive pattern.

When to Call Your Provider Immediately

Regardless of contraction timing, call your provider or go to the hospital if: your water breaks (even without contractions), you have heavy bleeding (more than spotting), baby stops moving or moves much less, you are less than 37 weeks (preterm labor risk), or you feel something is wrong. Trust your instincts — it is always better to be checked and sent home than to wait too long.

Frequently asked questions
How do I know if contractions are real labor?
Real labor contractions follow a pattern: they get closer together, last longer, and feel stronger over time. They do not stop when you change position or drink water. Braxton Hicks contractions are irregular, do not intensify, and often stop with rest or hydration. If you are unsure, time them for an hour — a clear progressive pattern indicates real labor.
How far apart should contractions be before going to the hospital?
The standard guideline is 5 minutes apart (measured start-to-start), lasting 60 seconds each, for at least 1 hour. This is called the 5-1-1 rule. First-time mothers can often wait a bit longer since labor tends to be longer. If this is not your first baby, consider going when contractions are 7-8 minutes apart, as labor often progresses faster.
