So the first one happened to confirm the pregnancy and to check if its in uterus itself. Second one to check heartbeat as it starts to show up post 5th week.

It deoends upon the necessity dear else normally 6 to 7 I guess including the anamoly scan..any specific reason why you went for two sonography by 7 weeks ?? Hope the pole and sac both visible by now ..TC n best wishes.;

There is no hard and fast rule for sonography every doc have their own way but gernally they do just one till 7. You can ask doc reason for sonography.
