when should I be worried?

There's days I don't feel our baby girl move much during the day, she'll wiggle a tiny bit and I only feel it a little.
And than there's days I feel her a lot.
But my question is, should I be as worried as if I were to not feel her at all?
As long as I feel atleast a couple movements in the day I should be okay or?
