Fluttering

I am around 12 weeks and 3 days. I get random fluttering feelings in my stomach in different places. Never the same. I am not gassy at all, no constipation or diarrhea anymore, still bit of nausea and fullness in my stomach. It is random. I work in child care and move around a lot and it's when I get a chance to sit down and then stand up again (to moving around) that I feel fluttering again. I know the baby is small, possibility of multiples could I be feeling them flutter around? Not kick per say but small movements?
