So, I got  chlamydia from my ex... and I went to go get tested after he called me and told me he had it. My results came back positive... so I told my current boyfriend to go and get checked. He did but his results came back negative?!?! And we hardly ever use condoms. I don't know if his doctors miss tested it or he just lucked out. Can someone explain it a bit more to me lol. Also, I got treated and it was already a week/ two weeks I believe? Before I had sex with my boyfriend after treatment and he got treated to just in case he had it and just say that the doctor did miss test it... him and I used a condom anyways to make sure because we had sex a day/ two after he got treated.. we both got the single dose of it. How long does it normally say for it to go away with a single dose?
