The hard, bulging belly of pregnancy is considered to be related to the appearance of contractions, which are categorized into true contractions and false contractions, and under normal circumstances, true contractions appear in the late stages of pregnancy before labor. False contractions may occur in the middle and late stages of pregnancy, especially when the pregnant woman is overworked and stimulated by coitus. False contractions are not regular, have long intervals, and do not cause dilatation of the internal cervical os, and the frequent occurrence of false contractions is likely to cause transient hypoxia of the fetus, affecting the normal development of the fetus. False contractions may also evolve into true contractions and initiate labor. Contractions during pregnancy should be handled on a case-by-case basis. If it is far away from the expected time of labor and the contractions are frequent, it is necessary to take drugs to inhibit contractions to control the contractions. Pregnant women should pay attention to rest, pay attention to a reasonable diet, don’t eat hawthorn and other foods that are easy to cause contractions, and take regular pregnancy checkups.
