  • Recognize that Braxton Hicks contractions are irregular, painless, and disappear when you drink water or change positions.
  • Monitor contractions for timing - irregular contractions without pain that fade within 30 minutes are typically normal.
  • Contact your doctor if contractions persist longer than 30 minutes or occur frequently, as this may indicate preterm labor.
  • Rest in a comfortable position when experiencing mild uterine tightness, but avoid unnecessary bed rest as it's not an effective treatment.
  • Understand that your uterus is a pear-shaped muscle that naturally contracts throughout pregnancy as it prepares for labor.

The uterus is a pear-shaped muscle that contracts throughout pregnancy. Braxton Hicks contractions cause harmless tightening that fades within 30 minutes, while persistent or regular contractions may indicate preterm labor requiring medical attention.

The word “uterus” comes from the Latin word for womb. The uterus is a muscle, about the size and shape of an upside down pear. The cervix, or neck of the uterus, connects the uterus to the vagina. During pregnancy, a mucus plug accumulates in the cervix to protect the uterus and growing baby [1].

What is happening to the uterus when you feel contractions?

A contraction occurs when the muscles of the uterus tighten. When a woman experiences a contraction, her abdomen will feel tight and hardened. Between contractions, the muscles relax and the abdomen will become softer [1].

Are early contractions without blood and pain not harmful?

If the uterus contracts irregularly, then it is safe. Braxton Hicks, or training contractions, differ from labor contractions as they are not painful and go away when you drink water or shift positions.

However, if the tightening of the uterus persists for a long time, then doctors may be concerned about preterm labor. If you are concerned about contractions, talk to your doctor about your symptoms [2].

How long is too long to experience contractions?

If the contractions are irregular and are not accompanied by pain, and dissipate within 30 minutes, there is nothing to worry about [2].

Is bed rest necessary?

Bed rest is not used as a treatment [3]. If there are mild pains, a feeling of a tightness in the lower abdomen, you need to relax, take a comfortable position or lie down for half an hour. If the tightness doesn’t fade within half an hour or is often repeated, contact your gynecologist.
