Contagious during incubation period?

i had protected vaginal sex but unprotected oral both ways. three days later i had unprotected sex with another partner. this partner has then suffered flu like symptoms and pain red bumps around her genitals but no blisters. She is going to the doctors today and i feel terrible i might have given her herpes. Does anyone know how likely viral shedding is within the incubation period to a possible exposure. I have not experienced any symptoms.
