The phenomenon of running water in late pregnancy should be observed and distinguished, because urine leakage often occurs in late pregnancy. The enlarged uterus and the entry of the fetus into the pelvis will compress the bladder, resulting in a decrease in the volume of the bladder, which can easily lead to urine flow when there is a little pressure. This is not constant and should come in bursts, with water flowing out only when the abdominal pressure is increased. When coughing or sneezing, there may also be a burst of water flow when the uterus is contracting, but when lying down or resting there is no fluid flow, which is normal and does not require special treatment. However, if there is a premature rupture of the amniotic sac and there is an outflow of amniotic fluid, symptomatic treatment should be taken in a timely manner. The symptom of amniotic fluid outflow is that there is continuous fluid outflow all the time, no matter if you are standing or lying down. This is a dangerous situation and should be noted as it can easily lead to cord prolapse after water breakage.
