Brief Answer:
Depends on how sensitive the bacteria is.

Detailed Answer:
Was a urine culture and sensitivity done before starting antibiotic. If so, please upload the result. If the organism was sensitive to Bactrim missing one dose in a 7 days course may not matter much.
For now drink sufficient water and take urispas or Vesicare for symptomatic relief. If symptoms persist after 5 days , a urine culture is to be done to see if you have any infection or it is only a hyperactive urinary bladder.
