The main characteristics of pseudo-contractions and true contractions are short duration, irregularity and long intervals, which can be seen in any period of the pregnancy process. The pseudo-contractions are usually associated with trauma to the abdomen such as impact, excessive anxiety and tension, and can also be seen after strenuous exercise. If the pseudo contractions are not accompanied by abdominal pain and other uncomfortable symptoms, and the frequency of contractions is low, there is usually no need to seek immediate medical attention, and daily observation is sufficient; if frequent pseudo contractions are accompanied by vaginal bleeding, severe abdominal pain and other symptoms, it is necessary to seek medical attention and improve relevant examinations to determine whether there are abnormalities in the growth and development of the fetus; 2, true contractions: true contractions usually last longer, and have a certain regularity and symmetry, and appear at the end of labor. They appear before the delivery. If a pregnant woman in the prenatal period does not have true contractions, she can be reviewed regularly to closely observe the pregnancy. If true contractions do not appear even after the labor has started, medications can be applied under the guidance of a professional doctor to promote cervical maturation, such as misoprostol and diazepam, which can help strengthen contractions.
