It is completely normal to experience a hard belly during pregnancy, especially in the later stages. This hardness is often caused by the tightening of your uterus as it prepares for labor. These contractions, known as Braxton Hicks contractions, are usually painless and irregular. They are your body's way of practicing for labor and helping to improve blood flow to the placenta. However, if you experience frequent or painful contractions, leaking fluid, vaginal bleeding, or any other concerning symptoms along with the hard belly, it is important to contact your healthcare provider immediately as these could be signs of preterm labor or other complications. Otherwise, enjoy this phase of pregnancy and remember to take care of yourself and rest when needed.
