I went into my 20 wk anatomy scan/ultrasound convinced I hadn't felt anything and even while watching our first LO move around on the screen, I still couldn't feel him move. I asked the tech and later the OB if it was "okay" if I hadn't felt him move yet and she said that it can be "normal". I ended up feeling him kick shortly after, maybe a week or so later?
Although, after I felt him move the first couple of times I realized that I probably felt him move numerous times before but always passed it off as little gas bubbles or something. Hoping that you will feel your LO soon and I agree with the PPs, try asking in the 2nd trimester board and you will be more current experiences.
