Hi,
Welcome to ehealthforum,
If the symptoms of UTI have persisted, it could suggest chances of resistant infection, re-infection or recurrence of infection, etc. Visit your doctor/gynecologist for urine analysis and culture test to identify the causative agent and get started on treatment as appropriate (based on examination findings and investigation results). If pregnancy chances are suspected, go ahead with getting thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously to prevent re-infection and avid having intercourse while being on the treatment course.
If you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet.
Take care.
