Haih mama, spotting masa GBS memang boleh jadi tapi scary kan? A few of my mum friends yang positive GBS juga ada spotting, so you're not alone, tapi since your doctor dah check and confirm it's related to the GBS, I'd say follow through dengan antibiotics habis habis and maybe go back if the spotting gets heavier or different colour. Sendiri pun jadi anxious time ni, so don't hesitate to call your clinic kalau rasa uneasy, better safe than sorry kan
