I was a GBS positive mom for my 1st pregnancy. Alhamdulillah, I went through a normal delivery. been given antibiotic drip during labor as well. My baby stayed in nursey. She did not need antibiotic drip as everything was okay, Alhamdulillah.
All I can say is consult and discuss your delivery plan with your doctor. Like what you are posting here now, you can ask for advice from your doctor too.
