Generally speaking, if the symptoms of cold and flu occur after pregnancy, most of them can be cured by drinking more water and paying more attention to rest. As long as the patient explains to the doctor that she is pregnant, the doctor’s medication is generally more prudent, and seldom adopts the medication that has an effect on the fetus for treatment. If the patient’s cold is more serious, it is necessary to go to the hospital in time, through the routine blood test, if the test result suggests that there is a bacterial infection, then it is necessary to use antibiotics for anti-infection treatment.
