I'm 10 weeks pregnant and went to see my GP with unusual discharge which I thought might be thrush. The GP did a swab which has come back as negative for thrush and bacterial vaginoses but positive for white blood cells. the GP told me this shows I have an infection and she suggested I get tested for chlamydia. I'm so shocked by this. I was last tested in 2005 and have been with DH since then. I've no reason at all to believe he's been unfaithful. I guess it's possible DH infected me at the start of our relationship, but would it be possible to have chlamydia for 8 years and have absolutely no symptoms until now? I've also had loads of infertility investigations which have shown nothing abnormal. DH has been tested too and has a low sperm count but nothing else. I really think it's unlikely to be chlamydia but if not what else could cuase this?
