Aww mama, I can feel your worry through the screen lah, tapi alhamdulillah the doctor sudah identify the BV infection dan you're on antibiotics already, that's the main thing! Spotting with BV is actually quite common, especially at 30 weeks, and a few of my mum friends had similar scares during pregnancy tapi everything turned out okay after the antibiotics kicked in. The fact that baby looks good on the scan is really reassuring, that's what matters most. Since you also have GDM, it's good you're already closely monitored, so definitely stick with your follow-up appointments and don't hesitate to rush to the hospital kalau ada heavier bleeding or other concerns, tapi from what you described, the progression from clot to brownish spotting sounds like it's settling down. Fingers crossed the 5-day course clears things up for you, you've got this, mama!
