i never got a proper scan from the tech team at 16 weeks but i did get a mini one from the widewife as they had a portable trolley scanner so they found that the easy way to check each heartbeat. i got proper scans from the tech team at 12, 20, 24, and will get at 28, 32, 36. every hospital is different but this is our UK one xx i had to push for the 24 week one under the NICE guidelines recently updated.
