How the Contraction 5-1-1 Rule Checker works
The 5-1-1 rule is a common guide for when to contact your provider or head to the hospital: contractions about 5 minutes apart (measured from the start of one to the start of the next), each lasting about 1 minute, for at least 1 hour. Your provider may give different instructions, for example if you have had a fast labor or a complication. Call right away if your water breaks, you bleed, the baby moves less, or you are worried. Example: with Time between contractions, start to start 5 min, Length of each contraction 60 sec, and How long this pattern has lasted 1 h, the result is 5-1-1 rule check = Matches 5-1-1: call your provider; Contractions per hour = 12; Contractions during the period = 12.
