Help!!

When I was 7 weeks pregnant I found out I had chlamydia and was treated. A month later at 12weeks I was tested again and it also came back positive. So I was retreated. I'm now 17 weeks and still having the cramps I had before so I have a feeling that the chlamydia had not gone away even though we haven't had sex... I'm so nervous about the baby.. Has anyone else gone through this???
