with a prostitute in Thailand on march 07. I was tested at 7 weeks after the event and it came back negative. My doctor said that it was 99% conclusive. Since then I have had no symptoms, I just got to thinking about it the other day because I hear something about a 3 month window period if it is a high risk incident. Anyone have any suggestions if I should be tested again. Other then that I have been in a completely monogamous relationship since then.
