Contractions vs Baby Movement

Has anyone else been told you were having a contraction when you thought it was normal baby movement? Apparently what I thought was my breech baby moving is actually contractions and I've been experiencing them for quite some time unknowingly! I feel so dumb but they don't hurt, just kind of uncomfortable, really. 
I was hooked up to some machine to measure them and when asked "are you feeling that big contraction?" I looked at her and said "huh, no?" because I've always thought that feeling was my baby moving!
It makes me nervous that I don't recognize a contraction vs baby movement! 😥
