My Vagina Smells Badly. No Infection, No Other Symptoms. No

My vagina smells badly. No infection, no other symptoms. No irritation no itching. Recent gyn visit was clear, but the odor was not happening then. Bathing twice per day and washing with spray to make sure I'm clean. I'm 59 years old and have not had a hysterectomy. My husband noticed it also. What could be going on?
