are they movements?!?!

Hi

I'm 16+3 FTM and for the past few days I've been having some strange twinges in the left lower part of my abdo (over where baby's legs are - had scan yesterday confirming it)

They sort of feel a little sharp but not painful, almost like mini electric shocks from inside now and then, and not like the pain or feeling I can get if I sneeze/cough or move too quickly which I suspected are ligament pains..

so i was wondering if this could be baby kicking I'm feeling? however it seems early.. and not a flutter or popcorn sensation I was expecting...

Can anyone relate or have ideas?

Thank you
