Anyone with trouble TTC after STD?

Hello, I am shamed to admit that about 5 years ago I was told I had chlamydia. My partner and I were both treated for it and continued having unprotected sex after the treatment time. I never went back for a follow up because I guess I was nervous. I have a ten year old son and have been trying for abut 6-7 months with my fiancé without success. I am SOO worried that the std damaged my internal sex organs and am wondering if anyone else has a story like mine with a happy ending?!
