Which signs may indicate that labor is approaching?

The signs that labor is approaching include an increase in Braxton Hicks contractions and the loss of the mucus plug. Braxton Hicks contractions, often referred to as "practice contractions," can become more frequent and noticeable as a woman's body prepares for labor. These contractions help to tone the uterine muscles and can be an indicator that labor is imminent.

The loss of the mucus plug, which serves to seal the cervical canal during pregnancy, can also signal that the body is preparing for labor. As the cervix begins to efface and dilate in anticipation of delivery, the mucus plug is expelled, indicating that the body is gearing up for the birthing process. This combination of signs is commonly noted by expectant mothers and can often be a clear indication that labor will start soon.

In contrast, while other options may present symptoms experienced during pregnancy, they do not specifically relate to the imminent onset of labor. Increased appetite, sleepiness, and heartburn are common in pregnancy but are not indicators of labor. Similarly, reduced energy, cravings, and swelling can occur at various stages of pregnancy and are not specific to labor. Heightened anxiety, back pain, and frequent urination could relate to the latter stages of pregnancy but do not directly signal that labor is
