Depo shot and Vaginal smell?

So I know tmi, but ever since I got the depo shot about 3 weeks ago, I've been having really bad discharge -is milky and very stinky- it's over now but I have a funky vaginal smell? Is it because of the shot messing with my hormones? Help? What can I do to not have a foul odor? I wash my body everyday and it's still lingering...
