Hey hun, you should be fine I think. How hard did he shake it??? I know at my doctors appt the baby wouldn't turn a certain way that the doctor needed it to turn, so the doctor shook my belly with the sonogram machine just so he can get the baby to turn and change position. It does shake the baby (like i saw on the screen), but the baby also moved. I was scared that the doctor did that because i was seeing the baby shaking, but im sure the doctor wouldn't have done it if it was bad. the baby did move and he got to see what he wanted. i think u should be okay.
