valtrex in third trimester

Norma
Ok so this is embarrassing but has anyone had any prior experience with this or currently having to take this suppressive medicine as a precaution (like me)? My doctor has assured me it won't affect my little one but honestly I'm stressing it now that I have the prescription in hand to begin taking for the remainder of my pregnancy! I've abstained from even taking Tylenol, except maybe once or twice. I'm 32 weeks pregnant today.
