Question: is it possible for you to have chlamydia but not your partner?
Answer: You can only be certain you have chlamydia if you have a test. Anyone can get chlamydia, including people who've only had one sexual partner in the last year. You're more likely to have it if you're under 25, have a new sexual partner, or more than one sexual partner in the last year, and if you haven't used condoms.
