Movement at 34 Weeks?

I am so scared of a still birth and this is definitely not helping: I feel my baby move everyday, but not a lot. I don't know if maybe I'm not noticing it but I'm so worried that something is going to happen to her. I heard that babies should move 10 times in a hour, but mine doesn't, not that I notice anyways. I talked to my OBGYN about this & she told me don't worry, but I still feel concerned..& she was also very rude to me because of my age (I'm 15.) I just feel like something is wrong & I don't know what to do.
