False labor, a feeling of the fetus descending, and redness of the eyes will occur before the start of labor. 1. False labor: Pregnant women will experience irregular uterine contractions, which usually appear at night and disappear during the day, with varying intervals and lasting no more than 30 seconds each time, and they will feel a slight backache and distension in the lower abdomen. 2. Fetal descent: As the fetal head descends into the pelvis, the uterine fundus will descend with it, and most pregnant women will feel more comfortable in the upper abdomen, increase in eating, and breathe well. 3. Seeing red: 1-2 days before labor, a small amount of bloody vaginal discharge will appear, known as seeing red, which is a precursor to labor. If the pregnant woman feels uncomfortable, she should go to the hospital in time.
