What do y’all think?

Yesterday i was shopping around all day and kept feeling like pushing inside my stomach every so often, like the baby was pushing off me trying to turn or something like that but I’m on 16 weeks..? Too early to feel that baby that much? I could tell it was not gas and it was at very random times but it was happen maybe 3 times in a row then stop for a good couple hours and I wouldn’t notice it all the time but I just wondering what y’all think.. baby or too early?
