I was in a relationship where I found out the male was an addict. I was exposed to him through sex and was tested 11 months after we last were together and had a negative result. This was a year ago. It is just about time for my next annual appointment where I will request another test, and I was told by a friend last night that he has tested positive and is sick. Is it possible the negative test was wrong, or was I just lucky? Should it have shown up in 11 months?
