Help with smell concerns!!

Emma
So I have always been very cleanly downstairs if you know what I mean, but lately I have been having some issues keeping it Fresh. 
I am currently on the 24 day challenge and I don't know if it's just because I am cleansing my body so I am releasing toxins but I can't help but feel dirty downstairs all the time. 
Everything I do seems to get me nowhere my, from cleansing pads to just taking ph balanced cleanser, I don't know what to do!
Any advice?
