I think I may have BV

Okay, so I have been having this "fishy" odor down there but I haven't had sex in over a year! I don't know if my pH balance became unbalanced because of soap? But I need to get it checked out ASAP! The only problem is that the certain hospitals that I am suppose to go to are all booked out until the end of August & I'm going on vacation after the 12th of August, so I honestly don't know what to do! This smell is bothering me bad. The hospitals that I have to go to, have an Express Care clinic and they treat UTIs, and other things, should I just walk in and go there?
