Sayang, ini memang boleh jadi scary terutama dah ada history of miscarriage sebelum ni. Tapi jangan worry dulu, kantung baby size yang macam-macam is quite common, and dating scans boleh ada margin of error jugak. Yang penting sekarang is kamu follow up closely dengan doctor kamu, go for the next scan and ask dia specifically what this means for your pregnancy, okay? A few of my mum friends pun ada situasi similar and alhamdulillah semua turned out fine, tapi setiap case lain-lain. I know waiting is hardest part, especially after what happened before. Stay strong, and jangan rasa malu nak ask your doc semua soalan yang kamu ada, that's what they're there for!
