I am about 32 weeks along. Since I know how the baby is positioned from the ultrasound I can usually distinguish knee from elbow, foot from hand. Her feet are still up closer to my ribs, about 2 or 3 inches above my belly button. Her head is nestled down low in my pelvis. I usually feel her arms and hands about half way between my belly button and vagina. These movements have a tendency to be sharper, sometimes even causing a pins and needles feeling, like getting a shot. Possibly from her fingernails?
When she moves her legs and feet it is more like a general pressure and stretching from the inside out, with the occasional good thump/kick. Normally the movements I feel are at the middle to surface of the uterus. Occasionally I will feel some punches deep within me, towards my back and bowels, but not very often. The movements are getting uncomfortable now that she is growing so fast. What hurts the most is when she scratches/punches my cervix. Ouch!
