Not feeling movement...

So I'm 21-ish weeks pregnant and my ultrasound tech yesterday made me feel like it's impossible that I'm not feeling any movement but I haven't felt anything. I have a very active little girl who is always kicking and moving her arms and doing flips and moving all over during my ultrasounds but I don't feel any of it. There has been no mention of any placenta issues that could prevent me from feeling movement. I'm also petite and have never had a big belly in my life so it's not that. I feel like there is something wrong with me. 😢
