ok i contracted chlamydia from my girlfriend who didnt kno she had it until i got it, i have been treated with 8 pills at once in my doctors office, four of the pills were white and the other four were a pinkish red, the nurse made me take them all rite their! i havent had sex
no it can't come back with out being reinfected.. With the amount you were treated with I would doubt that the treatment didn't work.
I would def. follow up with your doctor and get retested but I would also test for Trick and NGU. your GF and yourself should get a full STD work up to.
and one more thing my GF got a pep smer done when she went to get treated for the chlamydia so would the Doctor have found and treated her for Trick and NGU if she had it?
