Those who have HSV - pregnancy question

I had my first outbreak 7 years ago and since then have only had 2 more. The last one being almost 2 years ago now. I’m about to enter my third trimester of pregnancy and have been to awkward to speak about this to my doctor. I know I shouldn’t be embarrassed, but for some reason I just haven’t been able to bring it up. I’m hoping someone on here can give me some guidance. Is valtrex before birth absolutely necessary? Does it interact with any sort of medication that may be given during birth or with anything that would be given to me if I needed emergency c-section?

Has anyone not taken valtrex before birth (I think they usually recommend you start taking it as of week 36?) and everything went okay?
