Hygiene Help!

I need some serious help, I'm 29 weeks and I started leaking now. Sometimes a little pee if I sneeze or laugh and a lot of discharge. Because of this I feel like I'm getting a yeast infection, I'm very itchy and in pain. Also I can't see down there very well but I think I'm very red. The area that is very itchy is the outside not the inside. Sorry if this is TMI!! So basically I need some recommendations on what I can use besides monostat and if using panty liners would help with the leaking and not bother me with more itchiness.
