My girl got a call from her doctor today after her pap-smear she had a couple of weeks ago and discovered she had chlamydia. We just had a baby boy and when she was tested before she had the baby the results were negative and now they came back positive for her six week check up. You know she can't have sex for six weeks after pregnancy. So my question is how did she get it? She is the only person I have had sex with and she told me I was the only one. It's very confusing. Any feedback would help.
