As you enter your third trimester, your belly might surprise you by suddenly tightening into a hard ball, then relaxing again within a minute or two. No need to panic — this is most likely Braxton Hicks, your uterus "practicing" for the big day ahead.
How is it different from real labor?
The key difference is pattern and intensity. Braxton Hicks contractions are irregular, don't get stronger over time, and often disappear if you change position, drink water, or lie down to rest. Real labor contractions, by contrast, are regular, grow closer together, get progressively stronger, and don't ease up with a change in position.
- They tend to happen after physical exertion, dehydration, or intimacy.
- You'll feel more tightness than sharp pain.
- They're not accompanied by fluid leaking, bleeding, or ongoing lower back pain.
- They usually fade within an hour, or with rest and water.
Still, there are signs that warrant calling your doctor right away rather than waiting: contractions becoming regular and occurring every five to ten minutes, any fluid or blood, persistent severe lower back pain, or a noticeable drop in your baby's movements. Any of these, alone or together, deserve prompt medical evaluation even if your due date is still weeks away.
Dehydration is one of the most common triggers for these contractions, so make sure you're drinking enough water daily and taking regular breaks, especially if you're on your feet a lot. Remember — as uncomfortable as they are, these contractions are a healthy sign that your uterus is naturally gearing up for its big moment ahead.
