Braxton Hicks Contractions at 12 Weeks Pregnant
Braxton Hicks contractions are irregular practice contractions that can start as early as the second trimester. They help your uterus prepare for labor but are not a sign that labor is starting.

Frequently Asked Questions
How do I tell Braxton Hicks from real labor?
Braxton Hicks are irregular, don't get closer together, usually stop with rest/water, and are felt in the front. Real contractions are regular, get progressively stronger and closer, and often start in the back.
Can Braxton Hicks start in the second trimester?
Yes! Many women feel them starting around 20 weeks, though they're usually mild and infrequent. First-time moms may not notice them until the third trimester.
Are Braxton Hicks painful?
They're usually uncomfortable but not painful — more of a tightening sensation. If they become painful, regular, or you can't talk through them, they may be real contractions.
