I think some women do have a bit of burning/irritation. The thing is, most doctors swab discharge and LOOK at it under a microscope. It's fairly easy to determine if it is BV ad if they treated you with antibiotics, they most likely did this. It takes a minute to look at it and determine. They don't send it out but look right there in the office and in my case, in the exam room I was in. Have you completed your antibiotic? BV can be difficult to get rid of entirely and it can take more than one course of therapy and sometimes a partner has to also be treated as they can pass it back to you if they have it. Good luck
