My kicks aren't really kicks

Anyone, anyone....
I felt two or three distinct kicks over the last few days but nothing really yesterday and nothing so far today. 
What I have felt is something more like "roll"... Kind of like something is curled up and rolling about getting comfortable. Does anyone else know what the hell in talking about? 
I just want to know I'm not crazy and imagining things/this is normal. I'm 19 weeks today, FTM after LOTS of MCs and hardships to get here.
