Thank-you to every one for your quick reply. It is so great to have some support and I really appreciate everyones help.
Dachloster, thanks for the link. I have now read through it twice and it was very helpful.

AustraJoey, I can relate to how you feel as I am worried that if I have a CS then I will regret not going for the natural birth. If the professionals are telling me to go for it, I probably should.

Mgm I will be sure to let you know how I go as it sounds like you are in a similar predicament, (just ten weeks after me). I am sorry if I have made you worry. Apparently the transmit ion rate is extremely low, so I probably shouldn't be so concerned about it, nor should I be making others worry. I just want to make the right decision.
The name of the drug that I have been taking is Famvir, and my doctor said that it has been trialed with no deformities/side effects to the babies whose mothers have been on this drug. There was another alternative but I can not remember the name of it, but it had a slighly lower safety rating for pregnant women.
Went to my midwife today. She said the my last swab showed no virus present. She said that because I have been on the anti viral medication, this has helped to keep the virus at bay, even though I have been unable to get rid of the lesions.
I will have another swab at 37 weeks and if this is all clear I think I will go for a natural birth. If the virus is present then I will request a cesarean.
From what I can gather, the baby will be checked at birth for any infection and treated immediately with the antiviral medication if there is any transmition. Apparently the more serious risks are for the babies of mothers that do not even realise that they have genital herpes and find that their babies are sleepy and unresponsive 2 or 3 weeks after birth. I think early detection is very important. (I will be doing a bit more research on this over the next few days).
I know the risks are very small, and really I probably shouldn't be worrying too much about it. Just making sure I give my baby a good start.
Thanks all. Any more info or input would be great.
