Anatomy scan - tech pushing on stomach

I just had my anatomy scan yesterday.. My baby was super active and did not stop moving for a second so we have to come back in 3 weeks cause the utlrasound tech couldn't get all the shots she needed. When she tried to move the baby around she kept pushing like crazy on my stomach with the ultrasound wand .. And making my stomach bounce.. Has this happened to anyone else?? I'm kind of nervous I hope that this is common and she didn't affect the baby by doing that.. (the way she was pushing on my stomach)...   
Anyone experience the same thing? Is this normal protocol??
