Contractions are a phenomenon that occurs when a pregnant woman is close to giving birth, but of course there are real contractions and pseudo contractions. Therefore, when a pregnant woman in late pregnancy has frequent contractions, she should pay attention to the specific manifestations of the contractions to distinguish whether they are real or pseudo contractions, so as to do the relevant protection work. This condition can sometimes be a precursor to labor, and labor can occur after a few nights of frequent contractions. For contractions in labor, they can change from painless to painful, and the pain can last for more than ten seconds once every five or six minutes, and the pain can become more and more severe. If the contractions are like this, you should consult a doctor for examination. The diagnosis of labor can be made when the cervical canal becomes progressively shortened and dilated, and labor will usually take place more than 10 hours after labor. Of course, frequent contractions at night in late pregnancy are not necessarily a sign of labor, sometimes they may be pseudo contractions, and pseudo contractions are a one-time phenomenon, after a few nights of contractions, the contractions will disappear, and then the real labor will occur only after a week or two. If the pregnant woman is early in her pregnancy and not yet full term, she should consult a hospital promptly to rule out preterm labor and give birth control treatment if necessary.
