How do you get tested for herpes

I have an old obgyn doesn't know anything about zika virus or herpes besides" it's a cold sore on your lip" If you have never had that why do you think you have herpes and if you did you can't deliver vaginally.

I like her as an obgyn but I don't know what to do I think I could possibly have herpes because I feel tiny bumps might not be severe but I should take medicine? I'm very concerned I don't know what to do she said everything was normal but hasn't looked at me vaginally besides a swab for bacteria and that's it had a pap smear two years ago healthy. What test are available
