me too... for my second pregnancy, my doctor didn't perform 陰道起聲波 (coz i switched to another doctor)... he just performed the ultrasound scan from my belly & we could still see things v. clearly...
Bebichhichi,
yes, for my 1st miscarriage, the doc use 用陰道超聲波 to scan when i was 5 weeks pregnant...
for my last pregnancy, my present doctor said there's nothing to see at week 5 (apart from seeing the sac)... there's no heartbeat yet... so, my doc asked me to go back at week 7 to scan 肚皮 to check for heartbeat...
