You’ll take antibiotics for 3 to 7 days or as your doctor recommends. If your infection makes you feel uncomfortable, your doctor will probably start your treatment before you get your urine test results.
Your symptoms should go away in 3 days. Take all of your medication on schedule anyway. Don’t stop it early, even if your symptoms fade.
Many common antibiotics — amoxicillin, erythromycin, and penicillin, for example — are considered safe for pregnant women. Your doctor wouldn’t prescribe others, such as ciprofloxacin (Cipro), sulfamethoxazole, tetracycline, or trimethoprim (Primsol, Proloprim, Trimpex), that can affect your baby’s development.
