first baby jitters

Toya

This is my first pregnancy and I am scared. Of course I'm scared of labor and delivery pains but my main source of freaking out is lack of movement. I'm 5 months and 3 weeks with a boy but I rarely feel him moving about. I thought I felt him last night after eating then he just went away again. My question is how often do you feel your baby moving about? I have an appointment next week but I'm nervous.
