I realize this thread is very very old but I landed on t anyway so posting here for other moms to be. The comment about stomach muscles too thick sounds like an anterior placenta to me. I have that and I cannot feel the baby as much as most pregnant women say they do - even at 35 weeks. It also makes it harder for the heartbeat to be detected. I am not saying that women don't inherently feel the baby but yes there are cases when it is beyond what everyone else experiences and no one should feel shamed to want or have to get an ultrasound if it is determined to be necessary.
As for the reason I got to this page I am not sure if my question was answered. I don't feel any of the sensations described in this thread and am wondering if it is because I have AP. I will report on the position if I find out at my next visit.
After the initial post I went in for a check up and the nurse practitioner was able to feel the baby - who is head down. Here are the sensations I get - I will be very specific about my situation since the sensation may be specific to my body type.
I am very tall and as I mentioned before have Anterior Placenta.
1) The baby "dropped" over one weekend I suddenly started to feel a lot of pressure - even to the point of being painful - in the pelvic region.
So the head is pushing on the pelvic region. Note that it does not "feel like a head" or anything - just a lot of pressure. I know it is the head because the NP felt it
2) The movements I feel are either below my navel or on the side of my belly but in line with my navel. Never anything higher. I see some people have described as feeling it higher up but maybe their baby had not dropped or they are not as tall as I am. I am guessing those are limb movements based on the position.
3) Occasionally my whole tummy will jump around which I think may be hiccups
