when do braxton hicks contractions start
Braxton Hicks contractions, often called "practice contractions," typically begin in the second trimester of pregnancy, around or after week 20, though they may start as early as 6 weeks gestation but often go unnoticed until later.
Timing Breakdown
They become more frequent and noticeable from week 32 onward through the third trimester, ramping up as your body preps for real labor. First-time moms might not feel them as strongly early on compared to those who've been pregnant before, since the uterus is less sensitive.
- Earliest onset : Around 6 weeks (subtle, rarely felt).
- Common start : After 20 weeks (second trimester).
- Peak activity : Third trimester, especially nearing due date.
What Triggers Them?
Pregnancy hormones signal your uterine muscles to tighten sporadically, like a warm-up for delivery—your body's natural rehearsal without progressing to active labor. Dehydration, a full bladder, or baby movement can kick them off too.
Braxton Hicks vs. Real Labor
Spot the difference to ease worry—here's a quick guide based on medical insights:
Feature| Braxton Hicks 157| True Labor 57
---|---|---
Pattern| Irregular, random timing| Regular intervals, getting closer
together
Duration| 30 seconds to 2 minutes, unpredictable| 30-90 seconds,
lengthening over time
Pain Level| Uncomfortable tightening, no real pain; eases with movement|
Increasingly painful, doesn't stop with rest

Pro Tip : Time them—if irregular and relieved by walking, hydrating, or position changes, it's likely Braxton Hicks. Track details like frequency and feel, then chat with your provider.
