Yes he know I just don't want to get an outbreak...
How about STOP HAVING SEX if you don't want to infect anyone?! Your meds aren't herpes cryptonite. There's a chance your partner will eventually become infected even if you are continuing the meds.
Does he know you think you may have herpes? It not, you should tell him.
I am sexually active I am afraid to stop taking my meds I don't want to infect anyone after 18 weeks even with the meds shouldn't it show up by now?
I'd say 4 weeks to be absolutely sure.
I am going to have to blood retaken again this week should be 18 weeks Friday.. How long should I stop taking the meds before I have blood work redone?
I would say it was conclusive but for added peace of mind, cease the Valtrex immediately, there was no reason for you to start it in the first place, and retest at 16 weeks and take that answer as fact.
