Have the treated it with antibiotics? That usually clears it up. Although a lot of women have strep b that comes and goes and that's why there is no routine testing in the UK. I had it with my son, was told I would need antibiotics through labour but my labour was too fast so didn't get any. Although my son luckily had no complications. We just had to stay in hospital a few extra days to have him monitored. I imagine they will test you closer to your due date and if you still have it they will offer you iv antibiotics through your labour. It honestly isn't anything to stress about though, yes there are some horrible stories about it but it isn't common for it to be harmful to baby if it's treated.
