When the contraction reaches 4 minutes once and is regular, the labor can be delivered within 24 hours, but the specific time of delivery varies from person to person and needs to be judged according to the specific conditions of the fetus and the pregnant woman. If the contractions are regular and gradually increase in intensity, at the same time, the fetus is smaller, fetal position is more appropriate, the cervix of the pregnant woman is in good condition, the pelvis is larger, these conditions are conducive to the birth of the baby, may be waiting for a shorter period of time, the general primigravida need about 10 hours, after the birth of the mother needs about 6 hours to be able to complete the delivery. If the contractions are shorter and weaker, or if the fetus is larger or the woman has a smaller pelvis, it will take longer. Since the delivery time is affected by the size of the fetus, the orientation of the fetus, the height of the prenatal dew, the condition of the cervix, the size of the pelvis, the duration of contractions, the strength of contractions, and many other factors, the time of delivery can be determined by the doctor’s comprehensive analysis. Pregnant women should pay attention to adjusting their breathing during contractions, relaxing appropriately, and eating some food that can increase energy, such as chocolate. You can also massage your lower back with the help of your family to relieve the discomfort of soreness in the lower back and abdomen. Prepare the necessary items for labor, such as nursing pads, etc. Appropriate exercise can speed up the labor process.
