Braxton Hicks contractions

By trimester

Weeks 1–13

1st trimester

Braxton Hicks contractions are rare this early. Cramping in the first trimester usually comes from the uterus stretching or normal digestion, not practice contractions. Mention any cramping that feels sharp, one-sided, or does not ease up to your healthcare provider.

Weeks 14–27

2nd trimester

Many people notice their first Braxton Hicks tightening around now, often after a long day, a full bladder, exercise, or sex. It should stay occasional and mild at this stage. Call your healthcare provider the same day if it starts coming on a regular pattern or shows up with pelvic pressure, spotting, or fluid leakage, since it is still early for labor.

Weeks 28–birth

3rd trimester

Braxton Hicks tend to show up more often now as your body gets ready for labor. The real test is the pattern: they stay irregular and usually ease with rest or a position change, while true labor keeps getting closer together, longer, and stronger no matter what you do. Time your tightenings if you are unsure, and call your provider or the labor unit using the guidance in the FAQs below.

What does the evidence show for braxton hicks contractions?

• Braxton Hicks contractions are irregular and unpredictable: they skip around in timing and strength instead of settling into a steady pattern, and they usually stay mild or fade out rather than building. 1
• A simple check can help sort out what you're feeling: if walking around, switching position, or drinking a glass of water eases the tightening, or you can sleep right through it, that points to Braxton Hicks rather than true labor. 1
• Feeling occasional tightening throughout the day is normal, but six or more contractions in one hour, or contractions every 10 minutes or more often, is not, and that pace is worth a same-day call to your midwife or doctor. 2
• When the pattern is genuinely unclear, a quick cervical-length ultrasound check in the office or hospital can help your care team tell true labor from false labor with good accuracy, so getting checked is never a wasted trip. 3
• Combining a cervical-length measurement with one or two other simple checks gives clinicians an even more accurate read on whether contractions are early true labor or still false labor, which is why timing alone isn't the only tool your provider has. 4

When should I call my provider about braxton hicks contractions?

Call the same day if you count six or more contractions in an hour, if they settle into a pattern coming every 10 minutes or closer, or if they grow strong enough that you cannot walk or talk through them, since Braxton Hicks should stay milder than that. A low dull backache, pelvic pressure, or cramps that feel like a period alongside the tightening also point toward preterm labor rather than a normal practice contraction. Go in right away, regardless of timing, for any fluid leaking or vaginal bleeding. Whatever the pattern, any symptom that feels beyond your usual range is a reason to call: obstetric teams expect these questions and would rather hear early than late.
