Isn't it interesting how a fetus can fit in a small baby bump?

I'm 33 weeks pregnant by now but my baby bump isn't that large. It's actually smaller but according to my Doppler ultrasound today, both my baby's size and weight are above average. His weight is 2.400 kilos and size is estimated to be about 48 cm long. I'm told his limbs are very long.

I've gained weight at a very slow pace and even so, my facial and other features are still thin. This has me intrigued, how a fetus can fit in a small space. Not sure if this is common; a small baby bump but big baby. This explains the pressure I've been lately feeling. I feel as if I'm carrying a heavy bowling bowl at times, so tight and compressed.

I'm wondering if my baby must feel a bit uncomfortable in such a small space.

I was sent to have the Doppler ultrasounds because initially they were worred my baby was small for his size but it's the opposite. My belly is smaller for 7 months but my baby is bigger than average.
