after yeast and uti, i have an unusual odor?

Hi,
Welcome to ehealthforum,
Altered smell of vaginal discharge could suggest possibility of infection. Do not ignore your symptoms. The reappearance of symptoms and persistence of symptoms could suggest possibility of yeast or any other opportunistic infection that could have started due to prior antibiotic use (since antibiotics eliminate the infective bacteria as well as natural ones leading to opportunistic infections). Go ahead with visiting your doctor/gynecologist at the earliest for examination and vaginal swab/smear test done on the discharge to help identify causative agent and get you started on appropriate treatment to help you control the symptoms. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. 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 and lifestyle. If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment. Consider requesting for prescription of a Probiotic (to be used after you finish with taking the other medications) to restore the normal vaginal flora to minimize re-infection/repeat infections.
Take care.
