I just found out a week ago that my boyfriend's ex found out that she had chlamydia so I went and got tested a few days later. I got my results back and I am positive for Chlamydia. My boyfriend and I have been together for 5 months so that means that I have had it the whole time. Could I possibly be infertile? Does anyone know how long it takes for Chlamydia to cause infertility?
