Yes... I've heard about same day std testing, you can look for them
in google.... they can help you...
chlamydia testing can be done 5-7 days after exposure, the best way to test is a swab or urine- if urine make sure it is your first urine of the day and if that is not possible try to wait an hour to 2 after your last urine to test
