Have you felt movement?

I'm 15 weeks 1 day and haven't felt anything... which is fine but I'm nervous now. My first baby I felt at 17 weeks my second I felt at 14 weeks and now my third baby I thought I would be feeling movement by now but I don't. I'm obviously probably freaking out over nothing but I can't help it. I thought by the third baby I'd be a pro and not worry but it seems I worry more and more each pregnancy. I saw the baby at 8 1/2 weeks, 12 weeks, and 13 weeks. Each time everything looked or measured great. Anyone else feeling the baby yet or is anyone else as nervous as I am???
