I tested positive for Group B Strep at my first midwife appointment (c.9 weeks) and subsequently developed the symptoms of it as common to most UTIs. My doctor put me on two different courses of antibiotics. Antibiotics have always worked for me before but this time neither course has helped me to shift the bug. I am now 12.5 weeks, I've had my dating scan, and the baby looks fine, but I am suffering with the UTI and my doctors don't know what to do with me. Has anybody else had a similar experience and/or some advice to share? I can't help worrying about how this might affect my unborn child. Many thanks.
