Dehydration and feminine odor?

So TMI, but I've been struggling with a little bit of feminine odor, especially after work (I'm a waitress) so I figured it was just from sweating. But in order to be comfortable I've been showering like twice a day lately. I'm pretty dehydrated and my diet has just sucked lately. Could that have something, if not everything to do with my feminine odor? I don't think I have an infection because I'm not having any weird discharge. Thanks.
