Sayang, this really needs doctor's eyes, okay? Heart things kena take seriously, jangan delay the echo follow-up, that's important to make sure baby's okay. A few of my mum friends went through similar scares, and honestly the waiting was the hardest part, but the echo results usually put minds at ease. Just go do it as scheduled, and try not to stress too much in the meantime, murmurs in newborns are actually not uncommon, and doctors know what they're looking for. Kuat semangat! Let me know how it goes kalau you need to chat.
