Birth control odor help

Rebecca • Married to my high school sweetheart. Currently have 2 children Xavier Cole and Mariah Nicole.
Before I started birth control I never had a problem with vaginal odor. It has been about a month and a half since I had my first shot and no matter what I do or wash with it still smells bad. I know I do not have any infections or anything. It just smells bad. I don't know what else to try or do.
