I wondered if anyone's ever heard of this. I had a swab taken last week to check for infection down there after some weird discharge. No infection was found but it showed that I have high levels of group b strep. I've done a lot of research into it the last few days. My doctor prescribed me some antibiotics as my levels were high and if it's very bad it can get through your cervix some how and cause stillbirth/premature labour. My midwife however said it's pointless treating it during pregnancy because even if it goes it can come back in a few weeks. She said she'd never heard of it causing any harm during pregnancy only during labour so I'd have to have antibiotics during labour through IV. They pretty much left it up to me what to do. I've decided to take the antibiotics this week to try and at least reduce the levels if there's the slightest risk of stillbirth or premature labour. I do feel a bit uneasy taking antibiotics when they might not even do anything though and after the midwife said there was no need though. I know this is quite complex but does anyone have any advice?
