Has anyone ever experienced this......

After my yearly physical which I forgot includes a standard check for Chlamydia, my doctor called me and shocked the hell out of me with a positive test result....... I had back together with my current BF for a year now, we had a short break and up until that break he was the only guy I had been with. Period. 5 years of monogamy. But during our break we each had 1 new partner, so it was technically possible....... the man is a saint and handled the news well, he got tested negativeand was confident his "girl" was clean from our break. And I contacted my "guy" and he, and his new fling were both clean. . Only conclusion is that I had a false positive. After a year of no symptoms for either of us.. anyone ever get false reading?
