I got dignosed with Trichomoniasis but i dont under stand because me and my husband have been together for 2 & 1/2 years i havent slept with anyone else and neither has he. He is the only person i have had sex with that we dont use a condom. I have had 3 previous pelvic exams and none of them saw this but how did this Dr find it? She said she has told a lot of people in the past month they have it so is it possible she is wrong?
