Hi James,
Thanks for the response. Sorry I meant to say if she tests negative this week and hasnt had unprotected sex in the 3-6 months prior to this there is NO chance I have HIV, correct?
Yes. But in the end, only your test at the appropriate time matters
If she tests negative in this most recent test (she's expecting to) and claims she has not had unprotected sex prior to me, the likelihood of me having HIV is very slim, correct?
Is the likelihood of infection low; are the odds with me? How many people usually test positive in this case?
I wouldn't worry about the fact there was menstrual blood considering the fact you had a risk from unprotected sex. Take an antibody test 6-8 weeks after finalizing PEP then 3 months for a conclusive result.
