The pain in your stomach will become more and more severe when you are in labor. After entering labor, the contractions will last longer and the intervals will be shorter, along with the shortening of the cervical canal, the opening of the uterus and the gradual descent of the fetal head, which is the normal progress of labor. If the fetal head descends slowly or stops during the progress of labor or if the opening of the uterus does not open up with the regular contractions, it is an abnormality of the labor process, and the change of fetal heartbeat should be closely observed during the labor process. A professional doctor or midwife should deal with abnormal problems in time when they are found in the progress of labor. After entering labor, pregnant women should relax and listen to music to divert their attention, which can reduce pain and promote the progress of labor.
