Smelly downstairs.

I need help ladies. I'm 31 weeks. I'm a very hygienic person, but for the past few weeks I can seriously smell myself all the time and I feel like I'm constantly soaked down there and it's starting to drive me nuts. Anyone else have this problem? 
Update. I'm sure it's not a yeast infection or anything like that, is a bacterial infection the same thing? I assumed it was normal in pregnancy I was just hoping to get some advice and tips.
