I have been tested 5 times for herpes, Never has it been positive. My girlfriend just had her baby and within the last nine months im the only one she has had sex with. She had an outbreak this morning at 3 and went to the doctor at 830. she was tested many times because of her pregnancy. Is it possible that I carry the herpes virus and it not show up in my blood test?? I have never had an outbreak ever? I sound like a liar to my girlfriend and i need answers fast.
