It is normal to have a certain odor in the vaginal area, which can vary depending on your menstrual cycle or physical activities. Maintaining good intimate hygiene can help minimize these odors. It is recommended to wash the vulva daily with mild, unscented soap, avoid using irritating and scented intimate cleansers, wear cotton underwear, and avoid tight clothing. If you notice an unusual or strong odor, resembling fish with other symptoms like abnormal vaginal discharge, it may indicate an infection and it is important to consult a healthcare professional.
