Not flutters

I'm 16 weeks with my second. I remember pretty clearly what flutters felt like with my first, and so far I havent had actually "flutters" but a pressure sensation, like a rolling, pressure. It has happened more and more over the past two weeks, I can only assume it's the baby. Last night I pressed on my belly and then started feeling the pressure sensation... baby? Lol had anyone else experienced this instead of flutters? Is it just the baby doing par core in there or what? Lol
