After pregnancy, there were symptoms of urethritis, that is, frequent urination, urgency and pain in urination. If the symptoms are mild, conservative treatment can be adopted, that is, drinking more water, urinating frequently, giving light diet, paying attention to rest, and improving their own immunity; If the symptoms are obvious and need to be treated with drugs, you can choose antibiotics that have little impact on the fetus, such as cephalosporins. The risk of drug use in the first three months of pregnancy is relatively high. After three months of use of cephalosporins, the risk of impact on the fetus is significantly reduced.
