Violent coughing will increase the pressure in the abdomen, leading to rupture of the uterine membranes causing water breakage. If there are symptoms of upper respiratory infections such as coughing and phlegm, proper medication should be administered under the direction of a doctor, and if necessary, fluids may be used to treat the infection. If it fails to prevent water breakage, the pregnant woman must go to the hospital for examination after signs of water breakage occur, and the doctor will determine the fetal heartbeat and monitor the fetal heartbeat. If a brown or green tarry substance is discharged from the vagina, it is necessary to tell the doctor in time, because it may mean that the fetus has extruded and may even be dangerous. Pregnant women must take care to exercise in their daily life, improve their immunity and avoid colds. If water breakage occurs, you need to consult a doctor promptly.
