welcome to the board
If you call and get the results of your blood testing to post here, I can much better help you see if you need additional confirmatory testing done or not. All you need to post are the actual numeric results - e.g. hsv1 igg 8.98 and hsv2 igg 2.2 or whatever they are.
Also make sure your wife was definitely tested for herpes when she was pregnant. it's not a part of routine pregnancy testing so she might not have been.
So if you really do have herpes ( you didn't mention in your post if it was hsv1, hsv2 or both you tested + for ), why isn't your wife positive too? Really herpes isn't as contagious as folks think it is.
Once we confirm your status I will gladly give you more info on precautions for pregnancy.
