Auntie tak pernah encounter echogenic focus specifically, but honestly this is something worth discussing properly with your doctor or scan specialist, they can explain what it means for your baby's situation, sebab every case lain-lain. I know first-time mum worry is real, but this type of finding really needs proper medical context, bukan forum diagnosis. Have you already had a follow-up appointment or second opinion scheduled? Rooting for you, mama!
