Depends on technique: Transabdominal scans (see pic) with a low frequency probe and an heavy pt. with a tilted back uterus might not show a heartbeat (HB) at 9 wks, esp. if dates are a little off (irregular periods). BUT, a resonable trans vaginal U/S (probe in the vagina) would be expected to show a HB at 9+ wks. Maybe this will be done along & blood tests.
