It seems the doctor gave you the right test****
It really depends what test you took, HSV diagnosis are very confusing....but it sounds like the doctor gave you a if they've come back clean (negative) for herpes, its most likely so....but have you been blood tested (IgG) is the reliable test according to doctors,forums, CDC etc.....
I will add I have not have sex for atlest 6 months... the bumps appeared around a month and a half ago
