Chlamydia during pregnancy??

Has anyone ever fiund out they had chlamdya during their pregnancy? Early on like before 12 weeks and be told to take the antibiotic? I’ve done so much research and now I’m afraid that something might be wrong with the sac and all cause that’s what it said on google. Has anyone been treated for it during pregnancy ? And everything turn out just fine? I had no idea I had it. I was just tested in august and was clean so its extremely difficult for me to wrap my head around
