Phantom kicks: fact or fake?

Have ever had no reason to think you are pregnant, like regular periods, not late, no symptoms, and then you feel it...a futter, a flitter, a little butterfly inside you lol. And it stops you dead in your tracks, and you start frantically counting days in your head, then weeks bc well, movement! Then you whip out this handy lil app n see that your periods have been regular and on time the passed 5 months, sooooo now what? And then it happens again! You feel it again!!! Am I going crazy? Omg wth????
