My ex has Chlamydia.....

I just found out my ex has Chlamydia... the last time I touched him was over 4 months ago, and apparently the girl he slept with after me said he gave it to her. Who knows if I even have all the info but I have never been tested because my doctor said there was no need to if I've never had any symptoms... now I'm freaking out and wondering if I have it or possibly had it this whole time? I'm getting tested next week and I'm just freaking
