What is the difference between contraction duration and frequency?
Contraction duration is how long one contraction lasts. Contraction frequency is how often contractions happen, usually measured from the start of one contraction to the start of the next.
What does contraction interval mean?
Contraction interval usually means the time from the start of one contraction to the start of the next. Some people also talk about rest time, which is the break after one contraction ends before the next begins.
What is the 5-1-1 rule?
The 5-1-1 rule is a common timing guideline for contractions about 5 minutes apart, lasting about 1 minute each, for about 1 hour. Always follow your own doctor, midwife, or hospital instructions.
Can a contraction timer tell me if I am in labor?
No. A contraction timer can help you record timing patterns, but it cannot diagnose labor or replace guidance from your doctor, midwife, or hospital.
When should I call my doctor, midwife, or hospital?
Follow the instructions you were given. Call promptly if you are unsure, have bleeding, reduced baby movement, your water breaks, contractions start before 37 weeks, or something feels wrong.
