Running out of room?

Natallia • 24 yrs married 14/1/17, been waiting 2 years and finally have our little boy 💙🥰

Is it possible for baby to run out of room in there? I’ve been told that he has very long legs! And I can always feel him right up under my boobs, (very painful). Also when he moves it hurts! He’s definitely able to kick me in the ribs and squash my bladder at the same time! But I don’t think my belly is that big compared to others at my gestation! I have a growth scan a week tomorrow and they should tell me if I need to have a c-section depending on how big he is, I just don’t know if I should be concerned that he might not have enough room?
