For the past year I've had a onion Smell down there. I have no clue what's causing it. I don't use any soaps to clean that area, and I wear cotton underwear. It's so embarrassing, because I can sometimes smell myself through my clothes. The only time I don't have the smell is while on my period and a few days after. I've been to the Dr this summer during my annual pap smear and they checked for yeast, BV, and STD. Everything was good. Has anyone else had this? Should I go back to the Dr?
