Chlamydia is one of the most common sexually transmitted diseases. The infection is often symptomless and is easily passed on during unprotected sex. If there is a chance you could have caught chlamydia, it is best to get tested regularly. Chlamydia is very easily treated with antibiotics, but if left untreated it can cause serious long-term complications, including infertility.
If you have recently had unprotected sex and are worried that you may have caught chlamydia, you should wait 14 days before taking the test, as it can take up to two weeks for the infection to show.
