What other sort of work up have they been doing during your pregnancy with all of this? Have they tested you for yeast and bacterial infections vaginally? Do they suggest anything other than herpes as a cause? Have you had any more ob's cultured to confirm that it's all just herpes going on?
You can always try switching to acyclovir 400mg 3x/day and see if you do better on that. Some folks just don't tolerate valtrex.

Well first off i had a baby 3 years ago and they told me that if there were ANY signs that i should not vaginally have my baby and do a C-section if you have any syptoms it can be passed to the baby, but i think even if symptoms are not present that baby can be at risk and get it anyways (thats what i think) Just because they state that you can pass the virus even if you have no symptoms or sores, i think it should be your choice, but i gave birth vaginally with no complications if you have lots of redness and other things going on maybe go to a walkin clinic and see what maybe a second opinion would say if they say the same as your dr then i would not worried if they say something diffrent then maybe just maybe you should request C-section, personally i would rather be cut open then taking the chance to pass this to my child expecially if transmitted from giving birth it could cause other problems as well, i was told anyways. Hope this helped a bit and good luck!
