Aiii jangan worry sangat, GBS positive is actually very common, a few of my mum friends had it too and everything turned out fine! The main thing is during labor you'll get antibiotics through the IV, and that really does protect baby from getting infected, so doctors know exactly how to manage it. I know it feels like one thing after another (GDM dah enough stress kan), but this is totally manageable, do chat with your gynae about your birth plan so you feel more prepared and less anxious about it. You'll do great, mama!
