Wa'alaikumassalam! GBS tu Group B Streptococcus kan, memang scary la when you first dengar, tapi many of us mums went through it and babies turned out fine. A few of my mum friends kena positive during pregnancy screening, and they just did IV antibiotics during labour je, everything went smoothly without any issues for baby. Better you discuss this with your gynae so dia boleh guide you properly on what the next steps are, they're really familiar with handling GBS cases. Mana tau your doctor ada specific protocol, so don't worry too much lagi until you get more info from them okay!
