This pain can be constant, and it can be quiet or intensify from time to time. If a woman feels that there is a watery discharge from the vagina, then this most likely suggests that the uterus is intensively prepared for opening. During this period, a cork should go out — a bunch of mucus from the cervix. After the cork is released, amniotic fluid can move away, which is the last signal to the fact that the birth is about to begin, and very soon the woman in labor will need the help of specialists.
