At the 12 week scan they only have to check a few things; heartbeat and the NT measurement. If bubs is in a good position, an experienced sonographer is able to get the measurements pretty quickly. The 20 week scan is more detailed and takes longer so you should be able to get better look then.
It is unusual to be that sore after a scan. I would bring that up with the dr or midwife if you haven't seen someone about it yet.
