The pre-labor labor pains are intermittent sharp pains that accompany the uterine contractions that occur when a pregnant woman is about to go into labor. The pre-labor pains are intermittent, with the pain getting stronger and longer, and the intervals getting shorter. At the beginning, the uterine contractions are weak, with a shorter duration of about 30 seconds and a longer interval of about 5-6 minutes. As labor progresses, the contractions increase in strength and duration, and the intervals shorten. When the mouth of the uterus is fully opened, the duration of contractions can be as long as 1 minute, with intervals of only 1-2 minutes. Therefore, the contractions are progressively stronger, the pain increases and the rhythm becomes faster and faster. Then there will be dilatation of the uterine opening, descent of the fetal prenatal dew and rupture of the fetal membranes, etc. Pregnant women do not need to panic, and seize the time between contractions to rest and conserve enough energy. Before labor, women should take a small amount of food and drink to ensure that they have enough energy and that the anesthesia is safe for emergency caesarean section. If the contractions are not strong and the membranes are not broken, the mother can move around indoors appropriately.
