True contractions: the patient will feel the pain is more obvious, the beginning may appear to fall, with the gradual strengthening of contractions, the pain is more and more obvious, and the pain has a regularity, the duration is getting longer and longer, the interval is getting shorter and shorter, at this time to do the gynecological internal diagnostic examination, you can find that the cervical canal is shortened progressively, and is accompanied by the mouth of the uterus is dilated. 2. False contractions: common in late pregnancy, usually appearing at night and disappearing during the day, the abdomen has a feeling of tightness, and even a slight sense of falling, but usually not accompanied by pain, there is no regularity, gynecological examination is usually not accompanied by the disappearance of the cervical canal and dilatation of the uterine opening. It is recommended that pregnant women who can’t tell the difference between true contractions and false contractions should go to the hospital for examination, because false contractions may become true contractions with the prolongation of time, so they should be treated separately according to the week of pregnancy, and false contractions need to be controlled if they are not full-term.
