It sounds like a bacterial infection, they usually come with odor and discharge.
My Vagina Is Red, Not Itchy, And It's Starting To Smell, Not Like Fish, But A Weird Smell. And I Just Had A Yeast Infection About 3 Months Ago, And I Don't Think I Have It Again Because It Doesn't Itch, But What Could It Be?
actually it could be another yeast infection, or other infection. Even possibly an allergic reaction to something you may have used. you will need to see the doctor again.
You need to be careful it could be a bacterial infection or if you are sexually active it could be a std like the clap. I would get checked out as soon as possible
