23 weeks and no movement ever

I read on here a lot and google a lot and most moms say they have felt movement way earlier and that 20 weeks is average.

I’m 23 weeks. I don’t have these “bubbles pop” ever (my bubbles ARE gas lol), I have no movement, no kicks, nothing.

I have a doppler and hear the heartbeat is always pretty low (below the belly pooch.. like 3” below belly button, but above pelvic area) and on my US he was fine... just laying on his belly lol.

I have a small belly, but I still lay on my belly I still have no problem with anything. No cravings.

Nothing.

I have an appointment on the 18th when my doctor is back in town and I’ll be 24+ weeks then so I’ll for sure mention the lack of movement — but I’m really concerned.
