When you are about to give birth, there will be regular contractions, redness, a feeling of the fetus descending, and other manifestations such as frequent urination. 1. Regular contractions: Pregnant women will experience regular contractions before labor, the frequency of contractions will gradually increase, and the time between contractions will gradually shorten. The time of contraction will be reduced from 0.5~1 hour to 2~3 minutes, and the cervix will be dilated and the head of the fetus will be lowered. 2. Redness: Generally, 48 hours or 1~2 weeks before delivery, there are bloody leukorrhea and other manifestations, which may be caused by dilatation of the cervical canal due to contractions in late pregnancy, and the mucus plug in the cervical canal is dislodged into the vagina. 3. Fetal descent: some pregnant women will feel comfortable in the upper abdomen when they are about to give birth, which is due to the descent of the fetal head. 4. Other: pregnant women will also have frequent urination, lumbar and abdominal pain, increased frequency of bowel movements, abdominal relaxation and so on. It is recommended that pregnant women who experience redness or regular abdominal pain in the late stages of pregnancy need to be alert to the signs of impending labor. Pregnant women need to seek timely medical examination and follow the doctor’s advice to wait for labor.
