💡 Understanding Contractions & the 5-1-1 Rule

True Labour vs Braxton Hicks

True labour contractions come at regular intervals, get closer together over time, increase in intensity, and continue regardless of movement or position. They typically start in the lower back and radiate to the front.

Braxton Hicks contractions (practice contractions) are irregular, don't get closer together, and often stop when you change position or walk. They are usually felt in the front of the abdomen only.

The 5-1-1 Rule

This is a common guideline for when to go to the hospital: contractions are at least 5 minutes apart, each lasting at least 1 minute, for at least 1 hour. When you meet all three criteria, it's likely active labour has begun.

When to Call Your Provider

If your water breaks (clear or pink-tinged fluid), if contractions are consistently 5 minutes apart for an hour, if you have heavy bleeding, or if you feel decreased fetal movement. Always follow your provider's specific instructions.

How It Works

This timer tracks two things for each contraction: duration (how long the contraction itself lasts) and frequency (the time from the start of one contraction to the start of the next). Both matter for figuring out what stage of labor you’re in.

A commonly used guideline is the 5-1-1 rule: contractions coming every 5 minutes, lasting 1 minute each, for at least 1 hour, is often used as a signal that active labor may be underway and it’s time to contact your provider or head to the hospital. Your provider may give you a different threshold based on your specific situation.

Early labor contractions are often irregular and further apart, while active labor contractions become more frequent, longer, and more intense over time. If you’re ever unsure or concerned, call your provider rather than waiting for a specific pattern to confirm it.

Frequently Asked Questions

When should I go to the hospital?

Most providers recommend going when contractions meet the 5-1-1 rule: 5 minutes apart, lasting 1 minute, for at least 1 hour. If your water breaks, if you have bleeding, or if you’re concerned about decreased movement, go in sooner. First-time labours average 12–18 hours, so early labour is often best spent at home.

Duration: Time from the beginning of one contraction to the end of the same contraction. Frequency: Time from the start of one contraction to the start of the next contraction. Start timing when a contraction begins, stop when it ends, and note when the next one starts.

Braxton Hicks: irregular, don’t increase in intensity, stop with movement or position change, felt only in the front. Real contractions: regular, increase in intensity, continue regardless of activity, often start in the back and wrap around to the front.

Rest as much as you can, stay hydrated, eat light snacks if you’re hungry, take a warm shower or bath, use a birthing ball, practice breathing and relaxation techniques, and try to rest between contractions. Early labour can last many hours, so conserve your energy.
