weird feeling something is wrong.

I'm almost 29 weeks pregnant with a little girl. I had a miscarriage with my first pregnancy. I didnt even make it to the second trimester. This is my second pregnancy. I may just be paranoid. I keep feeling like something is going to be wrong with her. She moves regularly everyday but I feel like she does not move enough. She will kick a few times and adjust herself then she is still again for a while until she moves again later. Most days she will have a short period of time with a bunch of movement but I havent been able to pick up on a routine yet. I can usually nudge her or mess with my stomach and she will move. I just feel like she isn't active enough. What do you all think? How active are babies normally at 29 weeks? Am I being paranoid because of my last pregnancy?
