hey y’all. this post is kind of embarrassing but i’ve been having an awful smell down there for a few weeks and i have no idea what it is. i’ve had no discharge whatsoever. the smell kinda smells sour but also like dirt. i plan on seeing a dr next week but was wondering if anyone knows what this could possibly be? thanks!
