At the time you were tested (2 months), 98-99% of people would have already tested positive for the virus. I think, however, because you are certain your partner is
HIV positive, it is best to do a confirmatory test at the 3 month mark following your last exposure. If you did a test at 2 months, it's EXTREMELY EXTREMELY unlikely your result will change, but just to be completley safe, I suggest you do one.
An HIV+ male and a negative woman can have children.
