What Are Labor Contractions?
Contractions are rhythmic tightening and releasing of uterine muscles that help move baby through labor.
Braxton Hicks vs. Real Labor Contractions
Braxton Hicks contractions — practice contractions are usually irregular and may stop with rest, hydration, or position changes.
True labor contractions become closer, longer, and stronger over time and usually do not stop with rest.
What Is the 5-1-1 Rule?
The 5-1-1 rule is a common guideline for deciding when to call your doctor or go to the hospital.
Contractions are 5 minutes apart
Measured from the start of one contraction to the start of the next.
Each lasts at least 1 minute
Short contractions are less likely to indicate active labor.
This pattern has continued for 1 hour
Sustained patterns are more reliable indicators of active labor.
It is guidance, not a rigid rule. Follow your provider's specific instructions.
When to Call Your Doctor
Beyond the 5-1-1 pattern, contact your provider immediately if any of the following occur:
- !Your water breaks (even without contractions)
- !Heavy vaginal bleeding
- !Baby movements significantly decrease or stop
- !You have a high-risk pregnancy or special instructions
- !You feel something is wrong — trust your instincts
