Baby moving questions.

I'm 17 weeks pregnant, and I've been feeling my baby move for about two weeks now. She doesn't move tons but enough that I notice her presence. She is still small enough that her kicks and movements aren't a massive impact and are still just sweet little jostles. My question is, is it normal not to feel her all the time? Or as often as I would like? Am I still early enough that it's totally fine? I tend to over worry.
