yep, i too had this massive fear when i was pg with DD. i became totally clumsy around the 27 week mark onwards and ended up falling over a number of times. the biggest was when we were in italy and i fell forwards sprawling across cobblestones. i was so freaked out, so had it checked (great when you can barely speak the language LOL!) but like the others have said they tend to be pretty well protected in there. i, on the other hand was covered in bruises and scrapes.
