The determination of<unk>  is dependent on the history and physical assessment of the pregnant woman's abdomen, as there are no specific imaging tests for diagnosis. The key is to differentiate<unk>  from true labor<unk>  (see Table 1 above). Most commonly,<unk>  are weak and feel like mild cramping that occurs in a localized area in the front abdomen at an infrequent and irregular rhythm (usually every 10-20 minutes), with each<unk> lasting up to 2 minutes. They may be associated with certain triggers and can disappear and reappear; they do not get more frequent, longer, or stronger over the course of the<unk> . However, as the end of a pregnancy approaches,<unk>  tend to become more frequent and more intense. On a physical exam, some uterine muscle tightening may be palpable, but there should be no palpable<unk> in the uterine fundus and no cervical changes or cervical dilation.<unk>  do not lead to birth. More concerning symptoms that may require assessment by a healthcare professional include: * Any bleeding or fluid leakage from the vagina *<unk>  that are strong, frequent (every 5 minutes), and persisting for an hour * Changes or significant decreases in fetal movement
