I just found out from my ex boyfriend (as of 3/31) that he has Clamydia. He's already seeing someone else but swears that he hasn't slept with her. His girlfriend before me is apparently clean according to him so he is saying it is from me. I started having abnormal discharge in about the middle of our relationship. But I hadn't with anyone else I had ever been with. I just assumed it was part of my period about to happen. It has went away but I slept with him the day he left for good and now I'm having it again. I'm going to go checked but I'm curious on how I could have gotten it or if it was really from me? In the midst of our relationship I caught him talking about doing things with a girl who was just treated for an STD about two weeks ago. But he swears he never actually did anything with her. They only talked about it. I caught them before they could. He says... Anyway, if I do have it, Should I tell the other partners I had before him that they should get checked if they haven't already even though I never had signs with them? I don't feel like it is from me but I don't know what to believe at this point.
