Taking the valtrex is a bad idea.
One, you probably don't need it, and two, if you do have it, it could prevent you from getting an outbreak, thus alerting you that you do have it.
Your chances of getting herpes from this are so low, and I don't understand why you are freaking out.

Thank you for the calming words AJ I have been a mess for the past 4 days. You read a lot of stuff online about herpes being highly contagious. I am worried because she had symptoms a day or two later....maybe she is lying or she didn't know she had the symptoms the day we had sex. She was under a lot of stress the prior week and I know from my recent research, that that brings out the herpes. I am taking the Valtrex really to calm my nerves because if something shows up on me I am going to lose my mind!
Relax.
Your chances of getting herpes from a 1 time mostly protected encounter when your partner had no symptoms are very very low.
I wouldn't take the valtrex - you have no need to - and I would just stop worrying.
