What Causes Vaginal Odor And How Can It Be Treated?

hello
i'd like to ask u about the smell at my vagina recently. i wonder how it's come from. this is the first time i have it in my life. 2weeks ago i had inflammation about my clitoris and i bought "eve" which is cleaning product especially for vagina and after i used it 4days has smell comes out in my vagina. do i need to go to see a doctor?
thank u
