Braxton Hicks contractions are harmless tightening sensations that help the uterus prepare for labor. They usually feel like mild cramps or a firming of the belly that comes and goes without a steady rhythm. Having them more often doesn’t mean labor is starting. It’s often the body’s way of signaling the need for rest or hydration.
These contractions may appear more frequently when the body is dehydrated, after exercise, sexual activity, or even when the bladder is full. Drinking water and changing positions often help them subside within minutes. Staying hydrated throughout the day can help reduce how often they occur.
As pregnancy advances, Braxton Hicks contractions tend to become more noticeable because the uterus is larger and more active. They can briefly affect blood flow to the placenta, which may be part of how the body naturally improves oxygen delivery to the baby.
However, contractions that become painful, regular, or come with vaginal bleeding or fluid loss should never be ignored. In these cases, it’s important to contact an obstetrician or midwife right away to rule out preterm labor. Resting, drinking fluids, and avoiding self-medication are simple ways to stay safe during pregnancy.
