Alhamdulillah syukur sangat dengar jantung baby sihat! Memang scary gila masa doc cakap tu first, I understand exactly how you felt, a few of my mum friends went through similar scares, one said her baby was hiding behind rahim je so nampak gelap kat first scan. Rest well la and follow doc's advice about avoiding heavy work since you've had bleeding before, your body needs that break to let baby settle in properly.
