31 weeks and...

so I have hsv (for 2-3 years) and rarely have outbreaks however I currently am having a small one. I am 31 weeks pregnant and my doctor knows with plans to start me on meds at 36 weeks. with my daughter I had her at 37 weeks which my doctor knows.. my baby should be ok right with the meds? also it can't be transmitted through the placenta right? im just reading every thing and getting worried. also hoping they don't talk about it while I'm in labor as not a lot of people know and I'd like to keep it that way. I'm so nervous.
