Doctor's answer:

Hello, considering your situation, there may be a possibility of vaginitis. It is recommended that you get an early examination of vaginal secretions and a routine test for leukorrhea. This condition is generally caused by bacterial infection. First, it is necessary to identify what type of bacterial infection it is. Once the type of infection is confirmed, symptomatic treatment can be administered. It is important to maintain hygiene in the vaginal area to avoid infection. Pay attention to dietary nutrition and avoid eating raw, cold, spicy, or irritating foods.
