Dear Tara: Clear, odorless discharge is usually normal. The slight itching you have may be due to vaginal dryness associated with the hormonal changes during this age period. You need to consult your doctor for clinical examination and any infection, if diagnosed, then specific antibiotics may be required for treatment. Also taking antibiotics without proper diagnosis, may lead to development of antibiotic resistance and may also cause infection to flare up at times.
