I was diagnosed positive for Chlamydia in November of '14 due to a cheating boyfriend. I took 2 500 mg of Azithromycin December 8 and was retested the 27. The second came out negative. January 13 I had a Pap smear was was tested positive AGAIN with Chlamydia. I did not had sex since a week before my treatment back in December. Again, I took 2 500mg of Azithromycin. Two weeks later I was tested once more and it showed negative. Thank gosh right? Well, March 4 I went in for testing, a birth control renewal, and for a transvag ultrasound (I have PCOS). This test was positive! What the heck?! How are these staying positive if I have completely sustained from sexual contact?
