Worried mom

I'm pregnant with my 4th baby. I'm worried about my baby. I'm almost 14 weeks and I haven't felt any movement. With my third pregnancy I have video of him moving on the outside when I was just 15weeks. I've only heard my baby's heart 1 time during my 1st ultrasound. I was 11 weeks at the time. It was strong at 171 but the baby didn't move then either. The tech even commented on how still baby was. I know this probably is contributing to why I haven't felt the baby but it has me worried. I've never gone this long without feeling at least flutters even with my first pregnancy I felt movement by now. Anyone with similar experience
