There are not usually 5 signs that are clearly defined as necessarily being present before labor. Contractions, vaginal bleeding, water breakage and pain in the lower abdomen usually occur before labor. 1. Contractions: Before labor, a pregnant woman will experience regular contractions, which will gradually increase in intensity and shorten in interval. Generally speaking, if contractions occur every 3 minutes or so, it means labor is imminent. 2. Vaginal bleeding: If there is a small amount of vaginal bleeding in late pregnancy, especially in women who are already in full-term labor, it may be a sign that labor is imminent. 3. Water breakage: Water breakage refers to the rupture of the membranes of the fetus and the outflow of amniotic fluid, which is also a typical sign of labor. 4. Lower abdominal pain: If the labor is imminent, accompanied by uterine contractions pregnant women, there will usually be lower abdominal pain, and gradually strengthen the regularity. As each person’s physical condition and pregnancy are different, the signs before giving birth to a child will also be different, but if there is any abnormality, you should consult a doctor in time to check.
