Tbf everyone shows differently. It depends on how big baby is, how shallow your hips are shaped, how your uterus tilts (if it tilts forward slightly you will show earlier) and how much water you carry. I show super early. Size ten and I just look like I have shoved a basket ball up my top from super early on. But then I have 9lb babies, carry extra water and have all of the above. By the time I'm full term i physically can't get behind the wheel of a car as in order to fit my bump in I can't reach the steering wheel. I had to be induced on my due date with my last. Like people keep saying everyone's different but then you do get the people who show super early as well as those who get to 35 weeks and just look like they've over indulged on a buffet lunch!
