Odor "down there"

I have been having problems with vaginal odor and I don't know how to stop it. I got that special wash for down there and even got the freshening up wiped made for that area and spray deodorant. All Summer's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> products. I can't tell if it's just me or none of these products lasts that long and it is starting to bother me.

Is it supposed to have a slight odor naturally?
