I have a boyfriend of 1.5 years (February 2015 through now). I have been regularly checked for STDs for years and never diagnosed with one. In August 2015 and January 2016 I was tested for both chlamydia and trichomonas (among other STDs) and was negative. I'm not sure why I was tested at those times, but it was either a standard test or maybe because I was complaining about symptoms because I have been dealing with dryness and pain during sex for some time now which I assumed was caused by menopause. Last week I tested positive for both chlamydia and trichomonas. I was so shocked and did not believe the test result because I am in a committed relationship and we both had talked about STDs prior to starting our relationship and we tested negative at the outset. I went to a walk in clinic to get re-tested (prior to taking any antibiotics) but I haven't received the results from the second test. I am taking the prescribed antibiotics and so is my boyfriend. My boyfriend says he has not had sexual contact of any kind with any other person since we started dating and I know that I have not. My doctor suggested that I am naive, that this must be a recent exposure since January. I tried to ask the doctor about the possibility that the diseases could be dormant and he dismissed that theory. I feel like I'm insane. What the doctor said sounds logical, but when I listen to my boyfriend I believe him. My next medical appointment will be with a mental health counselor to try to deal with this. If anyone has any information that could explain how it is possible - or not possible - to test positive for these two STDs AFTER a minimum of 1.5 years of repeated exposure, please let me know. I should add that my boyfriend and I have almost always had unprotected sex from the very beginning. I am getting a full panel of tests for all STDs because I'm completely freaked out that if I have these two things I could have something else.
