"Most people who have chlamydia don’t notice any symptoms.
If you do get signs and symptoms, these usually appear between one and three weeks after having unprotected sex with an infected person. For some people the symptoms occur many months later, or not until the infection has spread."

The advice given on that site is clear: If you've got the slightest suspicion that you might have contracted chlamydia, GET A TEST!
