Empty sac at 8 week

For early stage they wont be able to point out the head etc but will check if there's an empty sac or a heartbeat. If they wish for you to comeback for another round of follow up they will let you know immediately.

Did you get the photos? Was it over the belly? I tried to ask about baby's head and all at 8 weeks too but they said too early to tell. If there is a reason to be concerned they will surely alert you.
