in early pregnancy a hormone is released into the urine. chlamydia is present in the vagina ot if left untreated can infect the whole reproductive system, its not too dificult to understand with the proper knowledge, which you obviously dont have
chlamydia can be tested for via a urine test. It has been such a rife sexually transmitted disease they had to make something non intrusive and not scary to start clearing the masses of this infection. So if you have a chemists that can test for this, you need to hand in a urine sample. I am also under the impression that they will be able to give you erythromycin to clear it up there and then. Once you have finished the course you should return to make sure it is clear. They wont ask you to go out the back for a vaginal swab.
The ignorance of some is absolutely astounding. If you are sexually active you are duty bound in my opinion to actively seek out these facts and not close your mind to all possibilities.
Oh and fine,thanks just so you dont look like a smug fool when debating anything to do with Chlamydia with Ratter again (who I have never seen post anything he is unsure of) the urine test works bcause when you have chlamydia your body OBVIOUSLY trys to fight the infestion, releasing enzymes into your system, very much like when you are pregnant and your body produces HCG!
