I started feeling the odd kick at 20weeks but didn't start feeling more kicks till i was 24weeks but some people do not feel there babies till later it all depends on your size and where your placenta is x
O and it depends on where ur placenta is it can make it harder to feel the kicks.
Everyone is different with my second it was 22 now on my 3rd 19+4 is when I started feeling he. I don't remember my first because it was over 6 years ago would have to look it up. Give it a couple weeks and if nothing don't freak just mention it to the Dr. Good luck
