Coughing during pregnancy is mainly considered to be caused by a respiratory infection. Since the body’s resistance is weaker during pregnancy, if you do not pay attention to diet and rest, you will easily suffer from upper respiratory tract infections, which will cause coughing and phlegm, and fever and other symptoms. If the symptoms are not very serious, you can generally pay attention to rest and diet first, and do not use medication first, most of them will also improve, mainly because oral medication at this time will affect the normal growth and development of the fetus. If the symptoms are more serious, you need to go to the hospital first for examination, generally need to draw blood tests, routine blood tests, also need to do sputum testing, drug sensitivity test. For bacterial infections, penicillin or cephalosporin antibacterial drugs can be preferred. These drugs do not have a great impact on the pregnant woman and the fetus, but also need to be treated with cough and phlegm relief drugs and other drugs under the guidance of a doctor.
