Hi,
Welcome to ehealthforum,
The symptoms that you describe do suggest possibility of infection, but it is difficult to comment on the cause for it without examining you. You should consider visiting your doctor/gynecologist at the earliest for examination and vaginal swab/smear test done to identify the causative agent and get started on appropriate treatment. Drink plenty of water. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid tight fitting clothes. If you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection. Avoid having unprotected intercourse while both of you are on treatment course.
Take care.
