I took a urine chlamydia test i've received a message today to tell me they are referring me to pregnancy with chlamydia, i do not no if i am pregnant so how do they? would the chlamydia test detect pregnancy?

Hmmm....: Maybe they do urine pregnancy tests on all women getting screened for STD's. Maybe all women screening positive for chlamydia go to the same clinic, labeled the "Pregnant with Chlamydia" clinic. Maybe they're just clairvoyant, or maybe it's a mistake. A chlamydia test by itself does not test for pregnancy. Perhaps the best thing to do is just to call them and ask.
