Sayang, first thing, follow your doctor's antibiotic course exactly as prescribed, okay? That's the best thing you can do right now for baby. I understand la the worry is massive, especially after your previous loss, but GBS is very manageable with antibiotics, and your doctor caught it early which is good. A few mum friends of mine kena the same during pregnancy and their babies turned out perfectly fine, the antibiotics work. Tapi please don't rely on tips; your doctor knows your full situation best, so any concerns or "what-ifs" outside what they've explained, check back with them directly, okay? They can reassure you properly. Try to rest and take care of yourself in the meantime. Sending you strength!
