Plus size and movement

Hey ladies. I'm 19w4d pregnant with my first. I think I'm feeling my little guy move. It feels like flutters or muscle twitches but it's low in my abdomen. I feel like the baby should be higher up, like closer to my belly button. Could this be baby or am I feeling something else?
