I had protected oral and vaginal sex with a call girl two weeks ago. No kissing. I was having seasonal allergies and then experienced a cold or flu like symptoms a few days after the encounter. Now two weeks later, I am experiencing my first-ever outbreak of hsv1 - fever blisters on my lip, along with headaches and feel like vomiting at times. I have done some research and it seems that the headaches are symptoms of fever blisters. I also read through the std and hiv forums that I was at low risk because it was protected sex. However, feeling nausea along with cold symptoms, I have been extremely worried that I have caught an std from that encounter. Please help.
