My boyfriend and I have been together for 4 years and we have 2 children together. When I found out I was pregnant with our first child I also found out I had Chlamydia. I got treated and so did he. Just last week I got my yearly check up and I have Chlamydia again! I have been completely faithful to my boyfriend and he said he has been completely faithful to me. I do believe him! Is it possible either my boyfriend or I was not fully treated three years ago? How could I have gotten infected again?
