Baby moving??

Heidi.jowett • 24 years young pregnant with my first I'm pommie (English) been in Australia 6 years :)
Im 12 weeks day 3 today 
When I had my scan Monday dead on 12 weeks baby was moving so much on the screen like it waved and even kicked me but I didn't feel the kick at all it was actually an incredible moment 
But sometimes when I lay down I feel little flutters in my stomach it's not gas as if I have gas it just comes out (my poor boyfriend) it's weird to explain but is it possible  my friend said she felt movement with her first baby at 13 weeks ??
