Hi Tiffany -
Like so many others have written, you can relax. Focus on preparing for the birth of your child, vaginally. A vaginal birth is enough to prepare for; I encourage you to put worries about herpes out of your mind and focus your mind on how you want the birth of your baby to be. Fear and worry are sooo natural when we're pregnant.
Your dr's know how to take care of you, an elective c-section is not a good idea, and you can do so much now to help yourself live with herpes that doesn't involve daily medication. Do more research online, you'll find information and help, and can pick what works best for you.
I have genital herpes, and had my first child last year. My dr's said we were all clear for a vaginal birth, my having herpes was a almost a non-issue, but we had a c due to other reasons. What happens at delivery time may depend on when you contracted herpes - if you've had it for a couple years or more, the chance of having an outbreak then is much less.
During my pregnancy, I did everything I could to prevent an outbreak, and didn't have one. You can take lysine, which is an amino acid, not 'medication', although there are some things to think about with that. See http://tinyurl.com/qsep43 - ###-###-#### mg a day has always worked well for me, even stopped outbreaks in the past when I felt that familiar tingle and swelling.
Avoid foods that trigger outbreaks, and eat ones that may be preventative. See http://tinyurl.com/o52v33 You've probably already improved your diet for your preganacy, so you've likely incorporated some of this guidance into your diet now.
Hope this helps,
C. S.
