My ex girlfriend told me she had chlamydia a day after i had sex with someone else. so I got the azitromycin, and got one for the person i had sex with, she apparently didn't take it until 3 days later, and we just had sex on her 6th day after taking the medicine. My questions are: did she contract chlamydia strong enough (after 3 days) to not be cured by azitromycin in 6 days? and also, can i re-infect her with her version of the bacteria (assuming she re-infected me with it)?
